Splicing factor, arginine/serine-rich 3, also known as SRSF3, is a protein that in humans is encoded by the SFRS3 gene. The protein encoded by this gene is a member of the serine/ arginine (SR)-rich family of pre-mRNA splicing factors, which constitute part of the spliceosome. Each of these factors contains an RNA recognition motif (RRM) for binding RNA and an RS domain for binding other proteins. The RS domain is rich in serine and arginine residues and facilitates interaction between different SR splicing factors. In addition to being critical for mRNA splicing, the SR proteins have also been shown to be involved in mRNA export from the nucleus and in translation. Two transcript variants, one protein-coding and the other non-coding, have been found for this gene.

Optimal dilution of the SFRS3 antibody should be determined by the researcher.

Amino acids MHRDSCPLDCKVYVGNLGNNGNKTELERA of human SFRS3 were used as the immunogen for the SFRS3 antibody.

After reconstitution, the SFRS3 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
