Anti-nuclear factor of kappa light polypeptide gene enhancer in B-cells 2 antibodies enable researchers to detect and measure the nuclear factor of kappa light polypeptide gene enhancer in B-cells 2 antigen in biological samples. This target is a reported synonym of the NFKB2 gene, which encodes nuclear factor kappa B subunit 2. This protein is known to function in extracellular matrix organization and inflammatory response pathways, among other biological roles. The human version of nuclear factor of kappa light polypeptide gene enhancer in B-cells 2 has a canonical amino acid length of 900 residues and a protein mass of 96.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types.
