LDLRAP1 Antibody - N-terminal region : Biotin (ARP55308_P050-Biotin)

LDLRAP1 is an adapter 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) . LDLRAP1 may be required for LDL binding and internalization but not for receptor clustering in coated pits. LDLRAP1 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. LDLRAP1 may also be involved in the internalization of other LDLR family members. LDLRAP1 binds to phosphoinositides, which regulate clathrin bud assembly at the cell surface.The protein encoded by this gene is a cytosolic protein which contains a phosphotyrosine binding (PTD) domain. The PTD domain has been found to interact with the cytoplasmic tail of the LDL receptor. Mutations in this gene lead to LDL receptor malfunction and cause the disorder autosomal recessive hypercholesterolaemia.

All conjugated antibodies should be stored in light-protected vials or covered with a light protecting material (i.e. aluminum foil) . Conjugated antibodies are stable for at least 12 months at 4C. If longer storage is desired (24 months), conjugates may be diluted with up to 50% glycerol and stored at -20C to -80C. Freezing and thawing conjugated antibodies will compromise enzyme activity as well as antibody binding.
