Anti-NPD001 antibodies are used in antigen-specific immunodetection in biological samples. The target NPD001 is a known alias name of the protein myocardin related transcription factor B, encoded by the MRTFB gene in humans. This 1088-amino acid residue protein is known to act as a transcriptional coactivator of serum response factor (SRF). It is localized to the nucleus of the cell and features O-glycosylated post-translational modifications. It is reported to be widely expressed in many tissue types.
