Predicted to enable RNA binding activity. Predicted to be involved in spliceosomal complex assembly. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleus. Predicted to be part of Prp19 complex; U2-type catalytic step 2 spliceosome; and post-mRNA release spliceosomal complex. Is expressed in brain; olfactory epithelium; and spinal cord. Human ortholog(s) of this gene implicated in basal cell carcinoma. Orthologous to human CRNKL1 (crooked neck pre-mRNA splicing factor 1).
