Alternative splicing of pre-mRNA SRSF3 controls viral early to late switch by regulation of gene expression of bovine papillomavirus type 1 and human papillomavirus through interaction with A/C-rich RNA elements (Jia et al., 2009). SRSF3 promotes the inclusion of exon 4 of its own mRNA and reduces the expression of full length SRSF3 protein (Juma and Nielsen, 1997). SRSF3 activates the inclusion of exon 10 of PK-M gene to promote the expression of oncogenic M2 isoform (Wang et al., 2012). SRSF3 inhibits the inclusion of a fibronectin cassette exon in the mature mRNA by interacting with RNA polymerase II C-terminal domain (de la Mata and Kornblihtt, 2006).
Termination of transcription SRSF3 plays a role in termination of transcription by binding to RNA downstream of the cleavage site, facilitating its degradation, and the release of Pol II from template DNA (Cui et al., 2008).
Alternative polyadenylation The 3-terminal exon 4 of calcitonin pre-mRNA contains an alternative polyadenylation site. SRSF3 affects the inclusion of exon 4 and alternative polyadenylation by the interaction with CstF (Lou et al., 1998).
RNA export SRSF3 associates with TAP promoting the export of intronless mRNA of histone H2a gene by interacting with a 22-nt RNA element (Huang et al., 2003; Huang and Steitz, 2001).
Protein translation SRSF3 is required for poliovirus translation initiation. SRSF3 binds to internal ribosome entry site (IRES) of a viral RNA by interaction with PCBP2 (Bedard et al., 2007).
