Figure Lengend Snippet: Sumoylation of FOXP1. ( A ) Representative immunoblotting of Foxp1 in the mouse neocortex during development. ( Right panel) Quantification of SUMO–Foxp1 immunoblotting. Immunoblots were first normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) at each time point and then subsequently normalized to nonsumoylated Foxp1 levels at embryonic day 15.5 (E15.5). Data are represented as means (±SEM). n = 3 per condition. ( B ) Endogenous coimmunoprecipitation of Foxp1 and SUMO-1 in the mouse neocortex at P0. ( C ) Schematic of FOXP1 protein showing the location of K636. (PolyQ) Polyglutamine motif; (ZF) zinc finger; (LZ) leucine zipper. ( D ) K636 is conserved across species. ( E ) Immunoblotting for Flag-tagged FOXP1 in 293T cells. Lysates were treated with 1 mM H 2 O 2 for 1 h ( left panel) or 100 µM ginkgolic acid for 6 h ( right panel) in the presence or absence of NEM. (FOXP1 WT) Flag-tagged wild-type FOXP1. The asterisk indicates a nonspecific band of the SUMO-1 antibody. ( F ) Immunoblot of immunoprecipitated wild-type Flag-tagged FOXP1 or Flag-tagged FOXP1 KR.
