Anti-C12orf22 antibodies enable researchers to detect and measure the C12orf22 antigen in biological samples. This target is a reported synonym of the CSRNP2 gene, which encodes cysteine and serine rich nuclear protein 2. This protein is known to function in the apoptotic pathway and the regulation of transcription, among other biological roles. The human version of C12orf22 has a canonical amino acid length of 543 residues and a protein mass of 59.6 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. C12orf22 is a member of the AXUD1 protein family.
