Function

SPG2_STRSG SRSF3_HUMAN Splicing factor, which binds the consensus motif 5'-C[ACU][AU]C[ACU][AC]C-3' within pre-mRNA and promotes specific exons inclusion during alternative splicing (PubMed:17036044, PubMed:26876937, PubMed:32440474). Interaction with YTHDC1, a RNA-binding protein that recognizes and binds N6-methyladenosine (m6A)-containing RNAs, promotes recruitment of SRSF3 to its mRNA-binding elements adjacent to m6A sites within exons (PubMed:26876937). Also functions as an adapter involved in mRNA nuclear export (PubMed:11336712, PubMed:18364396, PubMed:28984244). Binds mRNA which is thought to be transferred to the NXF1-NXT1 heterodimer for export (TAP/NXF1 pathway); enhances NXF1-NXT1 RNA-binding activity (PubMed:11336712, PubMed:18364396). Involved in nuclear export of m6A-containing mRNAs via interaction with YTHDC1: interaction with YTHDC1 facilitates m6A-containing mRNA-binding to both SRSF3 and NXF1, promoting mRNA nuclear export (PubMed:28984244).^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

The sequence-specific RNA-binding proteins SRp20 and 9G8 are the smallest members of the serine- and arginine-rich (SR) protein family, well known for their role in splicing. They also play a role in mRNA export, in particular of histone mRNAs. We present the solution structures of the free 9G8 and SRp20 RNA recognition motifs (RRMs) and of SRp20 RRM in complex with the RNA sequence 5'CAUC3'. The SRp20-RNA structure reveals that although all 4 nt are contacted by the RRM, only the 5' cytosine is primarily recognized in a specific way. This might explain the numerous consensus sequences found by SELEX (systematic evolution of ligands by exponential enrichment) for the RRM of 9G8 and SRp20. Furthermore, we identify a short arginine-rich peptide adjacent to the SRp20 and 9G8 RRMs, which does not contact RNA but is necessary and sufficient for interaction with the export factor Tip-associated protein (TAP). Together, these results provide a molecular description for mRNA and TAP recognition by SRp20 and 9G8.

Molecular basis of RNA recognition and TAP binding by the SR proteins SRp20 and 9G8.,Hargous Y, Hautbergue GM, Tintaru AM, Skrisovska L, Golovanov AP, Stevenin J, Lian LY, Wilson SA, Allain FH EMBO J. 2006 Nov 1;25(21):5126-37. Epub 2006 Oct 12. PMID:17036044^[7]
