Summary

U2 auxiliary factor (U2AF), comprised of a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the U2AF large subunit which contains a sequence-specific RNA-binding region with 3 RNA recognition motifs and an Arg/Ser-rich domain necessary for splicing. The large subunit binds to the polypyrimidine tract of introns early during spliceosome assembly. Multiple transcript variants have been detected for this gene, but the full-length natures of only two have been determined to date. [provided by RefSeq, Jul 2008]

Forensic Context

A study in mice demonstrated that the protein U2af2 (U2 small nuclear RNA auxiliary factor 2) was identified as a potential target of the U2AF2 in primary cardiomyocytes, where its protein level was downregulated following transfection with a miR-483-3p mimic, though this effect was not statistically significant [Xue et al. DOI:10.1161/JAHA.122.026160].
