About LDLRAP1

Cytogenetic location: 1p36.11 Genomic coordinates (GRCh38): 1:25,543,606-25,590,400 (from NCBI)

This gene has 7 transcripts (splice variants), 285 orthologues, 11 paralogues and is associated with 3 phenotypes. Ubiquitous expression in spleen (RPKM 14.0), lymph node (RPKM 12.3) and 25 other tissues.

Summary

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. [provided by RefSeq, Jul 2008]
