This gene belongs to the splicing factor SR family of genes. U2 auxiliary factor, comprising 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 small subunit which plays a critical role in both constitutive and enhancer-dependent RNA splicing by directly mediating interactions between the large subunit and proteins bound to the enhancers. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
GeneCards Summary for U2AF1 Gene
U2AF1 (U2 Small Nuclear RNA Auxiliary Factor 1) is a Protein Coding gene. Diseases associated with U2AF1 include ovarian mucinous neoplasm and myelofibrosis. Among its related pathways are Translational Control and Shigellosis. GO annotations related to this gene include nucleic acid binding and nucleotide binding. An important paralog of this gene is ZRSR1.
UniProtKB/Swiss-Prot for U2AF1 Gene
Plays a critical role in both constitutive and enhancer-dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron.
