SRp30b, also known as SC35, and Splicing factor, arginine/serine-rich 2 (SFRS2) is an essential splicing factor. This protein is encoded by the SFRS2 gene and is a member of the splicing factor SR family. SRp30b is involved in pre-mRNA splicing and is found in bodies in the nucleus that are highly enriched in poly(A) RNA. These nuclear bodies are referred to as speckles, SC 35 domains, or splicing factor compartments (SFCs). The purpose of these bodies is not completely characterized. Speckles correspond largely to, if not entirely to, ultra structures called inter-chromatin granule clusters (IGCs). SRp30b is required for pre-mRNA splicing events and is highly involved in spliceosomal interaction and assembly. This SR protein is necessary for assembly of the ATP-dependent splicing complex. It is also necessary for the ATP-dependent communication between pre-mRNA and U1 and U2 snRNPs.

Linear peptide corresponding to human SRp30b.
