Anti-NIP3 antibodies enable researchers to detect and measure the NIP3 antigen in biological samples. This target is a reported synonym of the BNIP3 gene, which encodes BCL2 interacting protein 3. This protein is known to function in autophagy pathways and brown fat cell differentiation, among other biological roles. The human version of NIP3 has a canonical amino acid length of 194 residues and a protein mass of 21.5 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include HABON and BCL2/adenovirus E1B 19 kDa protein-interacting protein 3.
