Enables promoter-specific chromatin binding activity. Involved in negative regulation of angiogenesis; negative regulation of blood vessel endothelial cell migration; and negative regulation of peptidyl-serine phosphorylation of STAT protein. Acts upstream of or within centrosome cycle; negative regulation of protein kinase activity; and regulation of cell cycle. Located in nucleus. Is expressed in several structures, including central nervous system; embryo mesenchyme; heart; sensory organ; and tibialis anterior. Used to study systemic lupus erythematosus. Orthologous to human GADD45A (growth arrest and DNA damage inducible alpha). [provided by Alliance of Genome Resources, Apr 2022]
