Protein functionPlays a role in clathrin-mediated endocytosis and trafficking, PubMed:11532990, PubMed:11577110, PubMed:11889126. Involved in regulating AMPA receptor trafficking in the central nervous system in an NMDA-dependent manner, By similarity. Regulates presynaptic nerve terminal activity, By similarity. Enhances androgen receptor, AR-mediated transcription, PubMed:16027218. May act as a proapoptotic protein that induces cell death by acting through the intrinsic apoptosis pathway, PubMed:11007801. Binds 3-phosphoinositides, via ENTH domain, PubMed:14732715. May act through the ENTH domain to promote cell survival by stabilizing receptor tyrosine kinases following ligand-induced endocytosis, PubMed:14732715. May play a functional role in the cell filament networks, PubMed:18790740. May be required for differentiation, proliferation, and/or survival of somatic and germline progenitors, PubMed:11007801, PubMed:12163454. {ECO:0000250|UniProtKB:Q8VD75, ECO:0000269|PubMed:11007801, ECO:0000269|PubMed:11532990, ECO:0000269|PubMed:11577110, ECO:0000269|PubMed:11889126, ECO:0000269|PubMed:12163454, ECO:0000269|PubMed:14732715, ECO:0000269|PubMed:16027218, ECO:0000269|PubMed:18790740, ECO:0000269|PubMed:9147654}.
