GPR61 Orphan Receptor Data Sheet

Orphan Receptor Name: GPR61

Description: GPCR (class A) (1)

Other names: Probable GPCR61 (2)

Molecular information: Human 451aa; chr. 1p13.3; Accession No. Q9BZJ8

Rat 451aa; chr. 2Q34: Accession No. Q8K4S5

Mouse 451aa; chr.3: Accession No. Q8R4N2 (3, 4, 5)

Structural information: (human) 7TMDs (1,4)

Homology with other receptors: 28-31% with certain histamine, adrenergic, serotonin,

and dopamine receptors (6)

Tissue location: Brain, particularly in hypothalamus and pituitary gland (5)

Putative ligand(s): No endogenous ligands (Orphan receptor) (5)

Agonists: none known

Antagonists: none known

Radioligands: none known

Principal transduction pathway: Gs-alpha/cAMP (6)

Physiological importance: Role in the regulation of appetite and body weight (1)

Pharmacological importance: Possible target for therapeutic interventions in metabolic

disorders such as obesity (1)

Mutations and Pathophysiology: None known (No specific mutations linked to human

diseases)

Comments: Inverse agonists for GPR61 have been identified and they act though a G-

protein dependent signaling pathway, thus providing concepts into their functional

modulation.

Abbreviations: GPCR- G-protein coupled receptor, aa - amino acid, chr – chromosome
