Anti-nSR100 antibodies enable researchers to detect and measure the nSR100 antigen in biological samples. This target is a reported synonym of the SRRM4 gene, which encodes serine/arginine repetitive matrix 4. This protein is known to function in cell differentiation and mRNA processing, among other biological roles. The human version of nSR100 has a canonical amino acid length of 611 residues and a protein mass of 68.6 kilodaltons. It is reported to be localized in the nucleus of cells. nSR100 is a member of the NSR100 protein family.
