Summary: Predicted to enable mRNA binding activity. Acts upstream of or within several processes, including hemopoiesis; melanocyte differentiation; and neural crest cell development. Predicted to be located in nucleus. Predicted to be part of U2 snRNP and spliceosomal complex. Is expressed in brain; neural tube; and trunk. Human ortholog(s) of this gene implicated in hepatocellular carcinoma and myelodysplastic syndrome. Orthologous to human SF3B1 (splicing factor 3b subunit 1).

What's a GeneRIF?

Data indicate that splicing factor 3b, subunit 1 (sf3b1) mutation causes aberrant splicing of sf3b1 resulting in functional and predicted non-functional transcripts and a 90% reduction in full-length Sf3b1 protein.
