Predicted to enable RNA binding activity. Predicted to be involved in positive regulation of mitochondrial RNA catabolic process and regulation of RNA splicing. Predicted to act upstream of or within anterior/posterior pattern specification and morphogenesis of embryonic epithelium. Predicted to be located in mitochondrial nucleoid and ribonucleoprotein granule. Predicted to be part of ribonucleoprotein complex. Predicted to be active in nucleoplasm. Orthologous to human GRSF1 (G-rich RNA sequence binding factor 1). [provided by Alliance of Genome Resources, Apr 2022]
