Anti-SRrp86 antibodies enable researchers to detect and measure the SRrp86 antigen in biological samples. This target is a reported synonym of the SREK1 gene, which encodes splicing regulatory glutamic acid and lysine rich protein 1. This protein is known to function in mRNA processing and RNA splicing, among other biological roles. The human version of SRrp86 has a canonical amino acid length of 508 residues and a protein mass of 59.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. SRrp86 is a member of the Splicing factor SR protein family.
