Putative Polycomb group protein ASXL1, Additional sex combs-like protein 1, ASXL1, KIAA0978,
Putative Polycomb group protein ASXL1 involved in transcriptional regulation mediated by ligand-bound nuclear hormone receptors, such as retinoic acid receptors (RARs) and peroxisome proliferator-activated receptor gamma (PPARG). It acts as coactivator of RARA and RXRA through association with NCOA1. ASXL1 also acts as corepressor through recruitment of KDM1A and CBX5 to target genes in a cell-type specific manner, the function seems to involve differential recruitment of methylated histone H3 to respective promoters.
