GPR177, also known as Wntless (WLS) or Evi, is an evolutionarily conserved transmembrane protein necessary for Wnt protein secretion. GPR177 localizes to compartments of the secretory pathway, including the ER, Golgi apparatus, endosomes, and plasma membrane. GPR177 is overexpressed in several cancer types including glioma and gastric cancer. Several isoforms of GPR177 exist due to the alternative splicing, with predicted MW around 62 and 51 kDa, respectively. The sequence can be processed by removing the signal peptide, which generates a mature form of 45-46 kDa. In addition, slow migragrating band above 62 kDa can also be detected because GPR177 is modified by N-linked glycosylation (PMID: 20549736).
