This entry represents the GOLD domain from wntless (WLS) proteins. WLS membrane trafficking and secretion chaperones for lipidated Wnt signaling proteins. They are homologous to GPR180, TMEM145, and TMEM181, which have been described as GOST proteins (for GOLD domain seven-transmembrane helix proteins) together with TMEM87A/B, GPR107, and GPR108, as they share the same domain architecture consisting of a GOLD domain atop of a membrane-spanning seven-transmembrane helix domain [1].

This entry represents the seven transmembrane domain of wntless (WLS) from Drosophila and its homologues, also known as MIG-14 in C.elegans which regulates endocytosis and secretion of the wnt ligand egl-20[1]. Newly synthesised EGL-20/Wnt binds to MIG-14 in the Golgi, targetting the Wnt to the cell membrane for secretion. AP-2-mediated endocytosis and retromer retrieval at the sorting endosome would recycle MIG-14 to the Golgi, where it can bind to EGL-20/Wnt for next cycle of secretion [1,3]. WLS is a membrane trafficking and secretion chaperone for lipidated Wnt signaling proteins [2]. It regulates Wnt proteins sorting and secretion in a feedback regulatory mechanism [2,4]. This entry also includes TMEM181, a cell surface protein associated with Escherichia coli CDT toxicity [2]. Members of this entry are homologous to GPR180 and TMEM145, and together with TMEM87A/B, GPR107 and GPR108, they have been described as GOLD domain seven-transmembrane helix (GOST) proteins given their domain architecture similarities. They all consist of a GOLD domain atop of a seven-transmembrane helix domain [2].	Domain
