Predicted to enable RNA binding activity; protein homodimerization activity; and transcription coactivator activity. Predicted to be involved in positive regulation of SMAD protein signal transduction; positive regulation of pathway-restricted SMAD protein phosphorylation; and response to oxidative stress. Predicted to be located in cytoplasmic stress granule; cytosol; and nucleoplasm. Is expressed in several structures, including central nervous system; gut; heart; retina; and urinary system. Orthologous to human RBPMS (RNA binding protein, mRNA processing factor). [provided by Alliance of Genome Resources, Apr 2022]
