Protein Information (annotations from UniProt)

Database IDHIV0008271
UniProt IDQ5SW96
Primary gene name(s)LDLRAP1
Synonym gene name(s)ARH
Protein nameLow density lipoprotein receptor adapter protein 1
Protein functionAdapter protein, clathrin-associated sorting protein, CLASP required for efficient endocytosis of the LDL receptor, LDLR in polarized cells such as hepatocytes and lymphocytes, but not in non-polarized cells, fibroblasts. May be required for LDL binding and internalization but not for receptor clustering in coated pits. May facilitate the endocytocis of LDLR and LDLR-LDL complexes from coated pits by stabilizing the interaction between the receptor and the structural components of the pits. May also be involved in the internalization of other LDLR family members. Binds to phosphoinositides, which regulate clathrin bud assembly at the cell surface. {ECO:0000269|PubMed:15728179}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:12451172}.
