    Summary
    Predicted to contribute to first spliceosomal transesterification activity and second spliceosomal transesterification activity. Involved in generation of catalytic spliceosome for second transesterification step. Located in nucleus. Part of U2-type catalytic step 1 spliceosome; U2-type catalytic step 2 spliceosome; and post-mRNA release spliceosomal complex. Human ortholog(s) of this gene implicated in breast cancer and pancreatic cancer. Orthologous to human SNW1 (SNW domain containing 1). [provided by Alliance of Genome Resources, Dec 2024]
