Summary: Predicted to contribute to first spliceosomal transesterification activity and second spliceosomal transesterification activity. Involved in generation of catalytic spliceosome for first transesterification step. Located in cytosol and nucleus. Part of Prp19 complex and U2-type spliceosomal complex. Orthologous to human XAB2 (XPA binding protein 2). [provided by Alliance of Genome Resources, Apr 2022]

NP_010704.1

Member of the NineTeen Complex (NTC); that contains Prp19p and stabilizes U6 snRNA in catalytic forms of the spliceosome containing U2, U5, and U6 snRNAs; null mutant has splicing defect and arrests in G2/M; relocalizes to the cytosol in response to hypoxia; homologs in human and C. elegans
