SRSF5 encodes the human gene, Serine/arginine-rich splicing factor 5. It may also be known as: Pre-mRNA-splicing factor SRP40; Splicing factor, arginine/serine-rich 5; Delayed-early protein HRS; SR splicing factor 5; SFRS5; SRP40. The encoded protein has an amino acid length of 272 and a mass of 31.3 kDa. Other isoforms may exist. SRSF5 is a member of the Splicing factor SR family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
