Anti-NIP45 antibodies enable researchers to detect and measure the NIP45 antigen in biological samples. This target is a reported synonym of the NFATC2IP gene, which encodes nuclear factor of activated T cells 2 interacting protein. This protein is known to function in the regulation of transcription, among other biological roles. The human version of NIP45 has a canonical amino acid length of 419 residues and a protein mass of 45.8 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells.
