The protein encoded by this gene is a cytosolic protein which contains a phosphotyrosine binding (PTB) domain. The PTB 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.^[5]
