SF3B6Splicing factor 3B subunit 6, is a protein encoded by SF3B6 gene in vertebrates.FunctionThis gene encodes a 14 kDa protein subunit of the splicing factor 3b complex. Splicing factor 3b associates with both the U2 and U11/U12 small nuclear ribonucleoprotein complexes of spliceosomes. This 14 kDa protein interacts directly with subunit 1 of the splicing factor 3b complex. This 14 kDa protein also interacts directly with the adenosine that carries out the first transesterification step of splicing at the pre-mRNA branch site.InteractionsSF3B14 has been shown to interact with SF3B1.
