NCBI Summary for AXIN1
This gene encodes a cytoplasmic protein which contains a regulation of G-protein signaling (RGS) domain and a dishevelled and axin (DIX) domain. The encoded protein interacts with adenomatosis polyposis coli, catenin beta-1, glycogen synthase kinase 3 beta, protein phosphate 2, and itself. This protein functions as a negative regulator of the wingless-type MMTV integration site family, member 1 (WNT) signaling pathway and can induce apoptosis. The crystal structure of a portion of this protein, alone and in a complex with other proteins, has been resolved. Mutations in this gene have been associated with hepatocellular carcinoma, hepatoblastomas, ovarian endometriod adenocarcinomas, and medullablastomas. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]
UniProt Comments for AXIN1
axin 1: is a negative regulator of the Wnt pathway, which is critical in stem cell signaling, morphogenesis, the mesenchymal-epithelial transition, and many cancers. Axin-1 functions as a tumor suppressor. Probably facilitates the phosphorylation of beta-catenin and APC by GSK3B, leading to their ubiquitination and subsequent proteolysis. Wild-type axin 1 can induce apoptosis in hepatocellular and colorectal cancer cells. Is downregulated during progression of esophageal squamous cell carcinoma. Mutation of the axin-1 gene is associated with hepatocellular carcinoma, anaplastic thyroid cancer, medulloblastoma and colorectal cancer. May have a role in oncogenesis in Hodgkin lymphoma. Axin1/2 mediate cross-talk between TGF-beta and Wnt signaling pathways.
