Anti-NYD-SP27 antibodies are used in antigen-specific immunodetection in biological samples. The target NYD-SP27 is a known alias name of the protein phospholipase C zeta 1, encoded by the PLCZ1 gene in humans. This 608-amino acid residue protein is known to be involved in the transport of ions and intracellular signal transduction, among other biological processes. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue expression, it is notably expressed in the testis and sperm.
