UBR5（ubiquitin protein ligase E3 component n-recognin 5），癌症关联基因，基因ID：51366，该基因编码孕激素诱导蛋白，属于HECT（与E6-AP羧基末端同源）家族hect家族蛋白作为e3泛素蛋白连接酶发挥作用，靶向泛素介导的蛋白水解的特异性蛋白。该基因定位于染色体8q22，在多种癌症中被破坏。这个基因可能在细胞增殖或分化的调节中起作用[由RefSeq提供，2008年7月]This gene encodes a progestin-induced protein， which belongs to the HECT (homology to E6-AP carboxyl terminus) family. The HECT family proteins function as E3 ubiquitin-protein ligases， targeting specific proteins for ubiquitin-mediated proteolysis. This gene is localized to chromosome 8q22 which is disrupted in a variety of cancers. This gene potentially has a role in regulation of cell proliferation or differentiation.
