Anti-phospho-UVRAG (Ser498)

UV radiation resistance-associated gene protein (UniProt: Q9P2Y5; also known as p63) is encoded by the UVRAG gene (Gene ID: 7405) in human. UVRAG is a key autophagic tumor suppressor that is mutated in several common human cancers. It contains four functional domains, a proline-rich domain, a lipid-binding C2 domain, a Beclin1-binding coiled-coil domain (CCD) and a C-terminal domain. It is a critical regulator of intracellular membrane trafficking, autophagy, and chromosomal stability. UVRAG is also involved in regulation of the COPI-dependent retrograde transport from Golgi and the endoplasmic reticulum by associating with the NRZ complex. Its function is dependent on its binding to phosphatidylinositol 3-phosphate (PtdIns3P). During autophagy UVRAG acts as regulatory subunit of the alternative PI3K complex II (PI3KC3-C2) that mediates formation of phosphatidylinositol 3-phosphate and is believed to be involved in maturation of autophagosomes and endocytosis. It is involved in maturation of autophagosomes and degradative endocytic trafficking independently of Beclin-1, but depends on its association with a class C Vps complex. UVRAG is also shown to enhance class C Vps complex association with a SNARE complex and promote fusogenic SNARE complex formation during late endocytic membrane fusion. UVRAG is also reported to promote DNA double-strand break repair by association with DNA-dependent protein kinase complex DNA-PK and activating it in non-homologous end joining. Disruption of UVRAG is shown to increase genetic instability and sensitivity of cells to irradiation. (Ref: Zhao, Z et al. (2012). Dev. Cell 22(5): 1001-1016).
