Anti-serine and arginine-rich splicing factor 6 antibodies are protein reagents that detect specific antigens. The serine and arginine-rich splicing factor 6 antigen is another term for the human protein serine and arginine rich splicing factor 6, encoded by the SRSF6 gene. The protein is reported to play a role in constitutive splicing and modulates the selection of alternative splice sites. Canonically, it has an amino acid length of 344 residues and a mass of 39.6 kilodaltons. Its subcellular localization is in the nucleus and it is widely expressed in many tissue types. The serine and arginine-rich splicing factor 6 protein is a member of the Splicing factor SR protein family.
