Predicted to enable identical protein binding activity. Predicted to be involved in several processes, including positive regulation of apoptotic process; positive regulation of cold-induced thermogenesis; and positive regulation of stress-activated MAPK cascade. Predicted to act upstream of or within negative regulation of protein kinase activity and positive regulation of MAPK cascade. Predicted to be active in cytoplasm and nucleus. Biomarker of mesangial proliferative glomerulonephritis. Orthologous to human GADD45G (growth arrest and DNA damage inducible gamma). [provided by Alliance of Genome Resources, Apr 2022]
