Facts about E3 ubiquitin-protein ligase MGRN1.
Impairs MC1R- and MC4R-signaling by competing GNAS-binding into MCRs and inhibiting agonist-induced cAMP production. Does not inhibit ADRB2-signaling.

Widely expressed, with highest levels in brain, heart, kidney and liver. In the CNS, especially prominent in the Purkinje cells of the cerebellum. In the skin, expressed in the basal layer of the epidermis and hair follicles, primarily in the outer root sheath. Isoforms 1, 3, 4 and 5 are equally expressed in the liver. Isoforms 1, 3 and 4 are most abundant in brain, kidney and heart, respectively.
