This entry represents the GOLD domain from GPR180, which is associated with TGF-beta signaling, as it regulates the activity of the TGF-beta receptor complex through SMAD3 phosphorylation [1]. Furthermore, GPR180 is also required for the action of Collagen triple helix repeat containing 1 (CTHRC1) to regulate brown and beige adipocyte activity and glucose homeostasis [2]. GPR180 was first to be an orphan Rhodopsin-like GPCR given structural similarities to GPCR transmembrane region, however, it was then confirmed not to signal as a a GPCR [1,2]. GPR180 is homologous to TMEM145, TMEM181 and WLS, which have been described as GOST proteins (for GOLD domain seven-transmembrane helix proteins) together with TMEM87A/B, GPR107 and GPR108, given they share the same domain architecture consisting of a GOLD domain atop of a membrane-spanning seven-transmembrane helix domain [1].
