    Summary
    Predicted to enable Hsp70 protein binding activity and Hsp90 protein binding activity. Involved in negative regulation of motor neuron apoptotic process and regulation of locomotor rhythm. Predicted to be located in cytoplasm. Is expressed in adult head. Orthologous to human RPAP3 (RNA polymerase II associated protein 3). [provided by Alliance of Genome Resources, Dec 2024]
