Predicted to be involved in spliceosomal complex assembly. Predicted to be part of Prp19 complex; U2-type catalytic step 2 spliceosome; and post-mRNA release spliceosomal complex. Human ortholog(s) of this gene implicated in basal cell carcinoma. Is an ortholog of human CRNKL1 (crooked neck pre-mRNA splicing factor 1).
