Anti-SPIN2 antibodies enable researchers to detect and measure the SPIN2 antigen in biological samples. This target is a reported synonym of the SPIN2A gene, which encodes spindlin family member 2A. This protein is known to function in the cell cycle and the regulation of transcription, among other biological roles. The human version of SPIN2 has a canonical amino acid length of 258 residues and a protein mass of 29.2 kilodaltons. It is reported to be localized in the nucleus of cells. SPIN2 is a member of the SPIN/STSY protein family.
