splicing factor 3b subunit 1

This gene encodes subunit 1 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron's branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome. The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008].

Recapitulate disease phenotypes

Endogenous knock-in cell lines enable a clear understanding of a gene or mutation’s contribution to a phenotype including conditional knockouts to model human disease

Confirm your results

We provide truly isogenic cell line pairs. Each cell model comes with the parental cell line as an additional control

Knockout and knock-in models

Our knock in models have more complex genetic modifications such as:

  • insertions
  • base pair changes
  • deletions
  • truncations
  • FLAG-tagged proteins for purification
