Anti-NYDSP5 antibodies enable researchers to detect and measure the NYDSP5 antigen in biological samples. This target is a reported synonym of the IQCH gene, which encodes IQ motif containing H. This protein is believed to play a regulatory role in spermatogenesis. The human version of NYDSP5 has a canonical amino acid length of 1027 residues and a protein mass of 117.3 kilodaltons, although 5 isoforms have been identified.
