Anti-C2orf57 antibodies enable researchers to detect and measure the C2orf57 antigen in biological samples. This target is a reported synonym of the TEX44 gene, which encodes testis expressed 44. The human version of C2orf57 has a canonical amino acid length of 395 residues and a protein mass of 41.6 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the testis.
