Predicted to enable mRNA binding activity. Predicted to be involved in regulation of mRNA splicing, via spliceosome and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleoplasm. Predicted to be part of spliceosomal complex. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in Raynaud disease. Orthologous to human HNRNPK (heterogeneous nuclear ribonucleoprotein K).
