Family relationships


This family consists of several eukaryotic splicing factor 3B subunit 5 (SF3b5) proteins. SF3b5 is a 10kDa subunit of the splicing factor SF3b. SF3b associates with the splicing factor SF3a and a 12S RNA unit to form the U2 small nuclear ribonucleoproteins complex. SF3b5 and SF3b14b are also thought to facilitate the interaction of U2 with the branch site [PMID: 12234937]. Also included in this entry is RDS3 complex subunit 10, another protein involved in mRNA splicing [PMID: 15565172].
