Anti-BCL9-2 antibodies enable researchers to detect and measure the BCL9-2 antigen in biological samples. This target is a reported synonym of the BCL9L gene, which encodes BCL9 like. This protein is known to function in the Wnt signaling pathway and myoblast differentiation, among other biological roles. The human version of BCL9-2 has a canonical amino acid length of 1499 residues and a protein mass of 157.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells. BCL9-2 is a member of the BCL9 protein family.
