Predicted to enable mRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome and production of miRNAs involved in gene silencing by miRNA. Predicted to act upstream of or within I-kappaB kinase/NF-kappaB signaling and regulation of transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of U2-type precatalytic spliceosome. Predicted to be active in nucleus. Orthologous to human SNIP1 (Smad nuclear interacting protein 1).
