Enables chromatin binding activity and sequence-specific DNA binding activity. Involved in several processes, including Sertoli cell development; cellular response to cAMP; and cellular response to follicle-stimulating hormone stimulus. Located in nucleus. Biomarker of mental depression and polycythemia. Human ortholog(s) of this gene implicated in several diseases, including Down syndrome; X-linked recessive disease (multiple); bone marrow cancer (multiple); colon adenocarcinoma; and myeloid leukemia associated with Down Syndrome. Orthologous to human GATA1 (GATA binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
