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 mixed connective tissue disease, and yellow fever, and among its related super-pathways are mRNA Processing and Generic Transcription Pathway. GO annotations related to this gene include RNA binding and snRNA binding. An important paralog of this gene is SNRPB2.

UniProtKB/Swiss-Prot: SNRPA_HUMAN, P09012

Function: Binds stem loop II of U1 snRNA. It 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. In a snRNP-free form (SF-A) may be

involved in coupled pre-mRNA splicing and polyadenylation process. Binds preferentially to the 5'-UGCAC-3' motif

in vitro
