SNRPA, Official Symbol SNRPAprovided by HGNC Official Full Name small nuclear ribonucleoprotein polypeptide Aprovided by HGNC Primary source HGNC:HGNC:11151 See related Ensembl:ENSG00000077312 MIM:182285; AllianceGenome:HGNC:11151 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as U1A; Mud1; U1-A Summary 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.
