Augurin is alternatively named oesophageal cancer-related gene 4 protein. The function of this family of transmembrane proteins, is to induce the senescence of oligodendrocyte and neural precursor cells, characterized by G1 arrest, RB1 dephosphorylation and accelerated CCND1 and CCND3 proteasomal degradation. Augurin has been found to stimulate the release of ACTH via the release of hypothalamic CRF. This family of proteins is found in eukaryotes. Proteins in this family are typically 145 amino acids in length.
