Also known as ITR

Summary

GPR180 (G protein-coupled receptor 180, HGNC:28899) is a protein-coding gene on chromosome 13q32.1, encoding Integral membrane protein GPR180 (Q86V85).

This gene encodes a protein that is a member of the G protein-coupled receptor superfamily. This protein is produced predominantly in vascular smooth muscle cells and may play an important role in the regulation of vascular remodeling.

  • 22 SNPs were isolated from the ITR locus by systematically screening genomic DNA from 48 healthy Japanese individuals (PMID:12730718)
  • A null GPR180 mutation segregates over two generations with iridocorneal angle dysgenesis, consistent with the view that deletions of this gene are the cause of MCOR. (PMID:25772937)
  • Microcoria due to first duplication of 13q32.1 including the GPR180 gene and maternal mosaicism. (PMID:32200002)
  • GPR180 is a component of TGFbeta signalling that promotes thermogenic adipocyte function and mediates the metabolic effects of the adipocyte-secreted factor CTHRC1. (PMID:34880217)
  • Lack of GPR180 ameliorates hepatic lipid depot via downregulation of mTORC1 signaling. (PMID:36726016)

PubChem BioAssay actives

1 with measured affinity, of 2 total; 1 most potent distinct compounds. Largely complementary to BindingDB; screening values are coarse (µM, 4 dp), so sub-nM hits tie at the floor.
