Predicted to enable RNA transmembrane transporter activity and mRNA binding activity. Predicted to be involved in mRNA transport. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in several cellular components, including neuron projection; nucleoplasm; and ribonucleoprotein granule. Predicted to be part of catalytic step 2 spliceosome and messenger ribonucleoprotein complex. Is expressed in central nervous system and sensory organ. Orthologous to human HNRNPA3 (heterogeneous nuclear ribonucleoprotein A3). [provided by Alliance of Genome Resources, Apr 2022]
