Recruits HSPA8/HSC70 to clathrin-coated vesicles and promotes uncoating of clathrin-coated vesicles (PubMed:15502813). Plays a role in clathrin-mediated endocytosis in neurons (By similarity). H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate Interacts with HSPA8/HSC70. Interacts with clathrin heavy chains. Brain. The N-terminus is blocked. Target for coat-associated casein kinase II in vitro.
