Summaries for SRSF1 Gene

Entrez Gene Summary for SRSF1 Gene

  • This gene encodes a member of the arginine/serine-rich splicing factor protein family. The encoded protein can either activate or repress splicing, depending on its phosphorylation state and its interaction partners. Multiple transcript variants have been found for this gene. There is a pseudogene of this gene on chromosome 13. [provided by RefSeq, Jun 2014]

GeneCards Summary for SRSF1 Gene

SRSF1 (Serine And Arginine Rich Splicing Factor 1) is a Protein Coding gene. Diseases associated with SRSF1 include Afibrinogenemia and Spinocerebellar Ataxia 31. Among its related pathways are Transport of Mature Transcript to Cytoplasm and RNA Polymerase II Transcription Termination. GO annotations related to this gene include nucleic acid binding and RNA binding. An important paralog of this gene is SRSF9.

UniProtKB/Swiss-Prot for SRSF1 Gene

  • Plays a role in preventing exon skipping, ensuring the accuracy of splicing and regulating alternative splicing. Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5- and 3-splice site binding components, U1 snRNP and U2AF. Can stimulate binding of U1 snRNP to a 5-splice site-containing pre-mRNA. Binds to purine-rich RNA sequences, either the octamer, 5-RGAAGAAC-3 (r=A or G) or the decamers, AGGACAGAGC/AGGACGAAGC. Binds preferentially to the 5-CGAGGCG-3 motif in vitro. Three copies of the octamer constitute a powerful splicing enhancer in vitro, the ASF/SF2 splicing enhancer (ASE) which can specifically activate ASE-dependent splicing. Isoform ASF-2 and isoform ASF-3 act as splicing repressors. May function as export adapter involved in mRNA nuclear export through the TAP/NXF1 pathway.

Post-translational modifications for SRSF1 Gene

  • Asymmetrically dimethylated at arginines, probably by PRMT1, methylation promotes localization to nuclear speckles.
  • Phosphorylated by CLK1, CLK2, CLK3 and CLK4. Phosphorylated by SRPK1 at multiple serines in its RS domain via a directional (C-terminal to N-terminal) and a dual-track mechanism incorporating both processive phosphorylation (in which the kinase stays attached to the substrate after each round of phosphorylation) and distributive phosphorylation steps (in which the kinase and substrate dissociate after each phosphorylation event). The RS domain of SRSF1 binds to a docking groove in the large lobe of the kinase domain of SRPK1 and this induces certain structural changes in SRPK1 and/or RRM 2 domain of SRSF1, allowing RRM 2 to bind the kinase and initiate phosphorylation. The cycles continue for several phosphorylation steps in a processive manner (steps 1-8) until the last few phosphorylation steps (approximately steps 9-12). During that time, a mechanical stress induces the unfolding of the beta-4 motif in RRM 2, which then docks at the docking groove of SRPK1. This also signals RRM 2 to begin to dissociate, which facilitates SRSF1 dissociation after phosphorylation is completed.

Q07955

UniProtKB/Swiss-Prot:

SRSF1_HUMAN :
  • The RRM 2 domain plays an important role in governing both the binding mode and the phosphorylation mechanism of the RS domain by SRPK1. RS domain and RRM 2 are uniquely positioned to initiate a highly directional (C-terminus to N-terminus) phosphorylation reaction in which the RS domain slides through an extended electronegative channel separating the docking groove of SRPK1 and the active site. RRM 2 binds toward the periphery of the active site and guides the directional phosphorylation mechanism. Both the RS domain and an RRM domain are required for nucleocytoplasmic shuttling.
  • Belongs to the splicing factor SR family.
