Enables RNA binding activity. Predicted to be involved in mRNA splice site selection. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in cytoplasm and nucleoplasm. Predicted to be part of spliceosomal complex. Predicted to be active in nucleus. Orthologous to human KHDC4 (KH domain containing 4, pre-mRNA splicing factor). [provided by Alliance of Genome Resources, Apr 2022]
