The LDLRAP1 Gene: What does it do?

LDLRAP1 Gene Description:

From MedlinePlus.gov

The LDLRAP1 gene (also known as ARH) provides instructions for making a protein that helps remove cholesterol from the bloodstream. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals. The function of the LDLRAP1 protein is particularly important in the liver, which is the organ responsible for clearing most excess cholesterol from the body.

The LDLRAP1 protein interacts with a protein called a low-density lipoprotein receptor. This type of receptor attaches (binds) to particles called low-density lipoproteins (LDLs), which are the primary carriers of cholesterol in the blood. The receptors sit on the outer surface of cells, where they pick up LDLs circulating in the bloodstream. The LDLRAP1 protein appears to play a critical role in moving these receptors, together with their attached LDLs, from the cell surface to the interior of the cell. Once inside the cell, LDLs are broken down to release cholesterol. The cholesterol is then used by the cell, stored, or removed from the body.
