Serine/arginine-rich splicing factor 2

SC35, splicing factor SC35
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 encoding the same protein and one non-coding transcript variant have been found for this gene. In addition, a pseudogene of this gene has been found on chromosome 11.

Splicing factor mutations and cancer.
Review
Ogawa et al., Kyoto, Japan. In Wiley Interdiscip Rev Rna, 2014
These mutations were heterozygous and mainly affected U2AF1 (U2AF35), SRSF2 (SC35), SF3B1 (SF3B155 or SAP155), and ZRSR2 (URP), which are engaged in the initial steps of RNA splicing, including 3' splice-site recognition, and occur in a large mutually exclusive pattern, suggesting a common impact of these mutations on RNA splicing.
