Anti-CYCB3 antibodies enable researchers to detect and measure the CYCB3 antigen in biological samples. This target is a reported synonym of the CCNB3 gene, which encodes cyclin B3. This protein is known to function in cell division, among other biological roles. The human version of CYCB3 has a canonical amino acid length of 1395 residues and a protein mass of 157.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells. CYCB3 is a member of the Cyclin protein family.
