Automated description from the Alliance of Genome Resources
Predicted to contribute to first spliceosomal transesterification activity. Predicted to be involved in generation of catalytic spliceosome for second transesterification step and mRNA 3'-splice site recognition. Predicted to localize to the Prp19 complex and spliceosomal complex. Orthologous to several human genes including ISY1-RAB43 (ISY1-RAB43 readthrough).
