TMEM52B (Transmembrane Protein 52B, also known as C12orf59) is a Protein Coding gene. The TMEM52B gene, located on 12p13.2, is conserved in chimpanzee, dog, cow, mouse, rat, chicken, and frog. 2 alternatively spliced human isoforms have been reported. The 183-amino acid protein has a reported mass of 20,002 daltons. The cellular localization is predicted to be membrane-associated. C12orf59 might act as a potential oncogenic protein in gastric cancer (GC). Researchers propose that the decreased C12orf59 expression status is a prognostic biomarker of ccRCC and cooperates with the loss of von Hippel-Lindau (VHL) all the while promoting renal carcinogenesis. 192 organisms have orthologs with human gene TMEM52B.
