HCAR1 (Hydroxycarboxylic Acid Receptor 1) is a Protein Coding gene. Diseases associated with HCAR1 include Retinal Degeneration, Late-Onset, Autosomal Dominant. 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 HCAR2. Acts as a receptor for L-lactate and mediates its anti-lipolytic effect through a G(i)-protein-mediated pathway.
