Description
LDLRAP1 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. This adapter protein is 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. This protein 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, and may also be involved in the internalization of other LDLR family members. Mutations in the LDLRAP1 gene lead to LDL receptor malfunction and cause the disorder autosomal recessive hypercholesterolaemia.

Descripción
Low-Density Lipoprotein Receptor Adapter Protein 1 (LDLRAP1), also known as ARH (autosomal recessive hypercholesterolemia protein), is a crucial adaptor protein that plays a pivotal role in the trafficking and internalization of low-density lipoprotein (LDL) receptors. It is predominantly expressed in hepatocytes and other tissues involved in cholesterol homeostasis. LDLRAP1 functions by linking the cytoplasmic tail of LDL receptors to clathrin-coated pits, facilitating receptor-mediated endocytosis of LDL particles. Mutations in the LDLRAP1 gene are associated with autosomal recessive hypercholesterolemia (ARH), a rare genetic disorder characterized by elevated plasma LDL cholesterol levels due to impaired clearance of LDL from circulation. This protein's interaction with other cellular components, such as AP-2 and clathrin, highlights its essential role in lipid metabolism and receptor recycling. As a significant contributor to cholesterol regulation, LDLRAP1 has been a subject of intense research, particularly for developing therapeutic strategies targeting cholesterol-related disorders.
