    RTL8, a family of small UBQLN2 interacting proteins, promotes nuclear translocation of UBQLN2. (A) Alignment of the protein sequences for the human (hRTL8) and murine (mRTL8) RTL8 proteins, showing a high degree of sequence homology. Similar residues are boxed in yellow; the bold typeface indicates that these residues are found in the majority of RTL8 homologs. Identical residues are bolded in white font and boxed in red. (B) Immunoblots of in vitro pull-down of recombinant purified protein <t>GST-UBQLN2</t> and His-mRTL8A. α-UBQLN2 and α-RTL8 antibodies were used for immunoblotting. UBQLN2-mRTL8A interaction was confirmed by detection of mRTL8A in the eluate (E), flow-through (FT), and washes (W1–3) as shown. (C) Immunoprecipitated FLAG-UBQLN2 pull down of RTL8 from brain lysates of FLAG-tagged UBQLN2 transgenic mice. (D) Representative images showing mRTL8A-dependent nuclear translocation of UBQLN2 and co-localization into subnuclear puncta. HEK293 cells were co-transfected with FLAG-UBQLN2 ( green ) and control HA-empty vector or HA-mRTL8A (left panel and right series, respectively). DAPI ( blue ) stained nuclei. White outlines in the merged image mark nuclei. (Scale bar = 20 μm). (E) Representative images showing mRTL8A-mediated nuclear translocation of endogenous (endog) UBQLN2. HEK293 cells were transfected with HA-mRTL8A and stained for endogenous UBQLN2 ( green ) and HA-mRTL8A ( red ). Merged images include DAPI to highlight nuclei ( blue ). Arrows highlight cells demonstrating localization of endogenous UBQLN2 to nuclear puncta containing HA-mRTL8A. Arrowheads identify cells not expressing HA-mRTL8A in which UBQLN2 is diffusely cytoplasmic (Scale bar = 10 μm). (F) Representative images showing fluorescence recovery after photobleaching (FRAP) of UBQLN2-mRTL8A puncta, demonstrating their dynamic nature. HEK293 cells were transfected with iRFP-UBQLN2 ( pink ), mFAP10-mRTL8A ( green ) and mApple ( red ). mApple serves as a morphology marker. (Scale bar = 5 μm). ( right ) iRFP fluorescence recovery following bleach was plotted as a percentage of the average fluorescence intensity of the puncta over time. Data are shown as mean ± SD. N=17 puncta.
