CC -!- FUNCTION: Transcriptional coactivator involved in neuroepithelial stem
CC cell differentiation and neurogenesis. Involved in particular in lens
CC epithelial cell gene regulation and stress responses. May play an
CC important role in lens epithelial to fiber cell terminal
CC differentiation. May play a protective role during stress-induced
CC apoptosis (By similarity). {ECO:0000250|UniProtKB:O75475}.
CC -!- SUBUNIT: Monomer (By similarity). Interacts with IFRD1/PC4 (By
CC similarity). Interacts (via IBD domain) with POGZ (via IBM motif) and
CC CDCA7L (via IBM motifs) (By similarity). Interacts (via IBD domain)
CC with KMT2A (via IBM motifs) with a moderate affinity whereas interacts
CC with the KMT2A-MEN1 complex with a greater affinity; MEN1 enhances
CC interaction of KMT2A with PSIP1 (By similarity). Interacts (via IBD
CC domain) with IWS1 (via IBM motif), MED1 (via IBM motif) and DBF4 (via
CC IBM motifs) (By similarity). {ECO:0000250|UniProtKB:O75475}.
CC -!- SUBUNIT: (Microbial infection) Interacts (via IBD domain) with feline
CC immunodeficiency virus (FIV) integrase (IN), determining its nuclear
CC localization, its tight association with chromatin and its protection
CC from the proteasome. {ECO:0000269|PubMed:15797927}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:O75475}.
CC -!- PTM: Citrullinated by PADI4. {ECO:0000250|UniProtKB:Q99JF8}.
CC -!- SIMILARITY: Belongs to the HDGF family. {ECO:0000305}.
