Brickell Biotech rabbit anti-stat5a polyclonal antibody
Upregulated HDAC2 phosphorylation is connected with downregulated ATP5O crotonylation in CS mice. (a, b) TMT-labeled phosphoproteomics showed that at the threshold of ≥1.2 or ≤ 0.833 , there are 117 downregulated and 60 upregulated phosphorylated proteins. (c) KEGG pathway showed that multiple pathways are lipid metabolism related. (d) We selected three deacetylases—HDAC2, KAT7, and CREBBP—to verify their relationship with ATP5O. Western blot showed that inhibition of HDAC2 phosphorylation at S424 with THP (CYGRKKRRQRRRSDSEDEGEGGRR) significantly decreased ATP5O, whereas inhibition of KAT7 phosphorylation at S102 with TKP (CYGRKKRRQRRRSSGSETEQVVDF) or CREBBP phosphorylation at S2361 and S2363 with TCP (CYGRKKRRQRRRQSQPPHSSPSPR) did not change ATP5O protein level at all. (e, f) We generated an ATP5O-S424 phosphorylation-specific antibody with a phosphorylated peptide SDS (phospho) EDEGEGGRR and verified the specificity through two ways. (e) Different amounts of non- and S424-phosphorylated HDAC2 peptide were loaded onto a dot blot PVDF membrane and detected by the HDAC2-S424 P antibody. Only phosphorylated HDAC2 peptide was detected in a dose-dependent manner. (f) When HDAC2-S424 P antibody was preblocked by the phosphorylated HDAC2 peptide, significantly less amount of endogenous ATP5O-K51 cr was detected. (g) Western blot showed that THP treatment significantly decreased HDAC2-S424 P (p-HDAC2) level and upregulated ATP5O-K51 cr (ATP5O cr ) level, whereas did not change KAT7-S102 P (p-KAT) level. Besides, THP treatment did not alter the level of HDAC1-S421 p at all, which shared the highest similarity with THP (Supp. Figure ). (h, i) By live imaging in Sf9 cells, when only ATP5O-WT-EGFP titer was added into sf9 culture media, as time progressed, green fluorescence rapidly increased; in contrast, when both ATP5O-EGFP and HDAC2-WT-TagRFP titers were added, as time went by, the red fluorescence (HDAC2) quickly increased, whereas the increment extent of green fluorescence (ATP5O) was significantly slowed down. (j) Coimmunoprecipitation and western blot showed that HDAC2 significantly interacted with ATP5O but rarely interacted with ATP5A1 or ATP5B. (k) GST-pulldown was carried out to verify the direct binding between ATP5O and HDAC2. GST-ATP5O and his-tagged HDAC2-TagRFP were cloned, expressed, and purified in E.coli (From left, the fourth and fifth lane, red asterisk-labeled) and sf9 cells (From left, the third lane, red asterisk-labeled), respectively. SDS-PAGE showed that GST-ATP5O could significantly pull down HDAC2-TagRFP (From left, the sixth lane, red asterisk-labeled). L-N. Western blot showed that when a fixed amount of ATP5O-WT and increasing amounts of HDAC2-WT were cotransfected into 293 T cells, ATP5O crotonylation level rapidly decreased (l, n); in contrast, when a fixed amount of ATP5O-WT and increasing amounts of HDAC2-S424A (a nonphosphorylable mutant) were cotransfected into 293 T cells, the decrement extent of ATP5O crotonylation level became much smaller (m, n). (o–s) When HDAC2-Flag and ATP5O-StrepII were cotransfected into 293 T cells at an increasing dosage, ATP5O crotonylation (o, p) and ATP levels both increased (q); accordingly, FAM126A and <t>STAT5A</t> levels also increased in a dose-dependent manner (r, s). (t–u) Western blot showed that compared with ATP5O-transfected 293 T cells, HDAC2 and ATP5O cotransfected cells had decreased ATP5O crotonylation, whereas inhibition of proteasome activity with MG132 significantly recovered ATP5O crotonylation level. (v, w) Western blot showed that in an in vitro ubiquitination assay with the ATP5O-E3 ubiquitin ligase complex immunoprecipitated from CS ovaries, the ATP5O ubiquitination level was significantly higher than the level in control ovaries. X. Model: ATP5O crotonylation is resistant to ubiquitination, whereas ATP5O-K51 cr decrotonylated by HDAC2 is susceptible to ubiquitination and protease degradation. Tubulin or actin was used as a loading control. * indicates p < 0.05 , *** indicates p < 0.001 , **** indicates p < 0.0001 .

Only phosphorylated HDAC2 peptide was detected in a dose-dependent manner. (f) When HDAC2-S424 P antibody was preblocked by the phosphorylated HDAC2 peptide, significantly less amount of endogenous ATP5O-K51 cr was detected.

Article Title: ATP5O Hypo-crotonylation Caused by HDAC2 Hyper-Phosphorylation Is a Primary Detrimental Factor for Downregulated Phospholipid Metabolism under Chronic Stress

doi: 10.34133/2022/9834963

Figure Lengend Snippet: Upregulated HDAC2 phosphorylation is connected with downregulated ATP5O crotonylation in CS mice. (a, b) TMT-labeled phosphoproteomics showed that at the threshold of ≥1.2 or ≤ 0.833 , there are 117 downregulated and 60 upregulated phosphorylated proteins. (c) KEGG pathway showed that multiple pathways are lipid metabolism related. (d) We selected three deacetylases—HDAC2, KAT7, and CREBBP—to verify their relationship with ATP5O. Western blot showed that inhibition of HDAC2 phosphorylation at S424 with THP (CYGRKKRRQRRRSDSEDEGEGGRR) significantly decreased ATP5O, whereas inhibition of KAT7 phosphorylation at S102 with TKP (CYGRKKRRQRRRSSGSETEQVVDF) or CREBBP phosphorylation at S2361 and S2363 with TCP (CYGRKKRRQRRRQSQPPHSSPSPR) did not change ATP5O protein level at all. (e, f) We generated an ATP5O-S424 phosphorylation-specific antibody with a phosphorylated peptide SDS (phospho) EDEGEGGRR and verified the specificity through two ways. (e) Different amounts of non- and S424-phosphorylated HDAC2 peptide were loaded onto a dot blot PVDF membrane and detected by the HDAC2-S424 P antibody. Only phosphorylated HDAC2 peptide was detected in a dose-dependent manner. (f) When HDAC2-S424 P antibody was preblocked by the phosphorylated HDAC2 peptide, significantly less amount of endogenous ATP5O-K51 cr was detected. (g) Western blot showed that THP treatment significantly decreased HDAC2-S424 P (p-HDAC2) level and upregulated ATP5O-K51 cr (ATP5O cr ) level, whereas did not change KAT7-S102 P (p-KAT) level. Besides, THP treatment did not alter the level of HDAC1-S421 p at all, which shared the highest similarity with THP (Supp. Figure ). (h, i) By live imaging in Sf9 cells, when only ATP5O-WT-EGFP titer was added into sf9 culture media, as time progressed, green fluorescence rapidly increased; in contrast, when both ATP5O-EGFP and HDAC2-WT-TagRFP titers were added, as time went by, the red fluorescence (HDAC2) quickly increased, whereas the increment extent of green fluorescence (ATP5O) was significantly slowed down. (j) Coimmunoprecipitation and western blot showed that HDAC2 significantly interacted with ATP5O but rarely interacted with ATP5A1 or ATP5B. (k) GST-pulldown was carried out to verify the direct binding between ATP5O and HDAC2. GST-ATP5O and his-tagged HDAC2-TagRFP were cloned, expressed, and purified in E.coli (From left, the fourth and fifth lane, red asterisk-labeled) and sf9 cells (From left, the third lane, red asterisk-labeled), respectively. SDS-PAGE showed that GST-ATP5O could significantly pull down HDAC2-TagRFP (From left, the sixth lane, red asterisk-labeled). L-N. Western blot showed that when a fixed amount of ATP5O-WT and increasing amounts of HDAC2-WT were cotransfected into 293 T cells, ATP5O crotonylation level rapidly decreased (l, n); in contrast, when a fixed amount of ATP5O-WT and increasing amounts of HDAC2-S424A (a nonphosphorylable mutant) were cotransfected into 293 T cells, the decrement extent of ATP5O crotonylation level became much smaller (m, n). (o–s) When HDAC2-Flag and ATP5O-StrepII were cotransfected into 293 T cells at an increasing dosage, ATP5O crotonylation (o, p) and ATP levels both increased (q); accordingly, FAM126A and STAT5A levels also increased in a dose-dependent manner (r, s). (t–u) Western blot showed that compared with ATP5O-transfected 293 T cells, HDAC2 and ATP5O cotransfected cells had decreased ATP5O crotonylation, whereas inhibition of proteasome activity with MG132 significantly recovered ATP5O crotonylation level. (v, w) Western blot showed that in an in vitro ubiquitination assay with the ATP5O-E3 ubiquitin ligase complex immunoprecipitated from CS ovaries, the ATP5O ubiquitination level was significantly higher than the level in control ovaries. X. Model: ATP5O crotonylation is resistant to ubiquitination, whereas ATP5O-K51 cr decrotonylated by HDAC2 is susceptible to ubiquitination and protease degradation. Tubulin or actin was used as a loading control. * indicates p < 0.05 , *** indicates p < 0.001 , **** indicates p < 0.0001 .

Decreased ATP5O-K51 crotonylation conduced to reduced ATP5O stability and decreased lipid metabolism. (a–c) Transfection of ATP5O-WT or K51A (inactive mutant) plasmid (in pcDNA3.1) into 293 T cells and western blot by ATP5O-K51 cr antibody showed that ATP5O-K51A had significantly decreased crotonylation level (a, b), accordingly, ATP5O K51A-transfected 293 T cells had significantly lower cytoplasmic ATP level than ATP5O-WT-transfected 293 T cells. (d–g) Western blot showed that inhibition of ATP5O crotonylation with a competitive peptide TAC (CYGRKKRRQRRRATALYSAASKEKKL) significantly reduced ATP5O-K51 crotonylation (d, e) and gross ATP5O (f, g) levels, similar to CS treatment.
