General annotation (Comments)

Function	Receptor for medium-chain free fatty acid (FFA) with carbon chain lengths of C9 to C14. Capric acid (C10:0), undecanoic acid (C11:0) and lauric acid (C12:0) are the most potent agonists. Not activated by short-chain and long-chain saturated and unsaturated FFAs. Activation by medium-chain free fatty acid is coupled to a pertussis toxin sensitive G(i/o) protein pathway. May have important roles in processes from fatty acid metabolism to regulation of the immune system. Ref.5
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Expressed predominantly in hematopoietic tissues. High levels detected in the bone marrow and lower levels in the peipheral leukocytes and lung. Also expressed in brain, heart, muscle, colon, thymus, spleen, kidney, liver, placenta and intestine. Within the leukocyte population expression is higher in neutrophils and eosinophils relative to T- or B-lymphocytes. Ref.5 Ref.1 Ref.2
Induction	By lipopolysaccharide in the monocytic leukaemia cell line THP-1. Ref.5
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
