Anti-serine and arginine-rich splicing factor 10 antibodies are protein reagents that detect specific antigens. The serine and arginine-rich splicing factor 10 antigen is another term for the human protein serine and arginine rich splicing factor 10, encoded by the SRSF10 gene. The protein is reported to be a splicing factor that in its dephosphorylated form acts as a general repressor of pre-mRNA splicing. Canonically, it has an amino acid length of 262 residues and a mass of 31.3 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is widely expressed across many tissue types. The serine and arginine-rich splicing factor 10 protein is a member of the Splicing factor SR protein family.
