Anti-SRp30a antibodies enable researchers to detect and measure the SRp30a antigen in biological samples. This target is a reported synonym of the SRSF1 gene, which encodes serine and arginine rich splicing factor 1. This protein is known to function in mRNA processing and RNA splicing, among other biological roles. The human version of SRp30a has a canonical amino acid length of 248 residues and a protein mass of 27.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include ASF, SF2, and SF2p33.
