Component of clathrin-coated pits and vesicles, that may link the endocytic machinery to the actin cytoskeleton. Binds 3- phosphoinositides (via ENTH domain). May act through the ENTH domain to promote cell survival by stabilizing receptor tyrosine kinases following ligand-induced endocytosis. {ECO:0000269|PubMed:11889126, ECO:0000269|PubMed:14732715}. This is the function of HIP1R (huntingtin interacting protein 1 related, ENSG00000130787).
