Summaries for HCAR1 Gene

Entrez Gene Summary for HCAR1 Gene

  • G protein-coupled receptors (GPCRs, or GPRs), such as GPR81, contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.[supplied by OMIM, Feb 2005]

GeneCards Summary for HCAR1 Gene

HCAR1 (Hydroxycarboxylic Acid Receptor 1) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and cAMP signaling pathway. GO annotations related to this gene include G-protein coupled receptor activity. An important paralog of this gene is HCAR3.

UniProtKB/Swiss-Prot for HCAR1 Gene

  • Acts as a receptor for L-lactate and mediates its anti-lipolytic effect through a G(i)-protein-mediated pathway.

Tocris Summary for HCAR1 Gene

  • Orphan 7-TM receptors (orphan GPCRs) are receptors for which there are no defined ligands. Traditionally, receptors are characterized by specific ligands and stimuli; the search for ligands of orphan receptors is therefore akin to reverse-engineering this process.
