Summaries for SNRPA Gene

Entrez Gene Summary for SNRPA Gene

  • The protein encoded by this gene associates with stem loop II of the U1 small nuclear ribonucleoprotein, which binds the 5' splice site of precursor mRNAs and is required for splicing. The encoded protein autoregulates itself by polyadenylation inhibition of its own pre-mRNA via dimerization and has been implicated in the coupling of splicing and polyadenylation. [provided by RefSeq, Oct 2010]

GeneCards Summary for SNRPA Gene

SNRPA (Small Nuclear Ribonucleoprotein Polypeptide A) is a Protein Coding gene. Diseases associated with SNRPA include Connective Tissue Disease and Suppression Amblyopia. Among its related pathways are mRNA Splicing - Major Pathway and Gene Expression. GO annotations related to this gene include nucleic acid binding and RNA binding. An important paralog of this gene is SNRPB2.

UniProtKB/Swiss-Prot for SNRPA Gene

  • Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5 splice-site and the subsequent assembly of the spliceosome. U1 snRNP is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. SNRPA binds stem loop II of U1 snRNA. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. May bind preferentially to the 5-UGCAC-3 motif on RNAs.
