Anti-U1A/SNRPA Antibody Picoband®

U1 small nuclear ribonucleoprotein A is a protein that in humans is encoded by the 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.
