Anti-SRY box 13 antibodies enable researchers to detect and measure the SRY box 13 antigen in biological samples. This target is a reported synonym of the SOX13 gene, which encodes SRY-box transcription factor 13. This protein is known to function in the morphogenesis of anatomical structure and gamma-delta T cell differentiation, among other biological roles. The human version of SRY box 13 has a canonical amino acid length of 622 residues and a protein mass of 69.2 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells.
