Gene: SF3B3 (splicing factor 3b subunit 3) Homo sapiens
Symbol: SF3B3
Name: splicing factor 3b subunit 3
Description: Predicted to have nucleic acid binding activity. Involved in mRNA splicing, via spliceosome and negative regulation of protein catabolic process. Localizes to nuclear lumen and spliceosomal complex.
Type: protein-coding
RefSeq Status: REVIEWED
