Enables DNA-binding transcription factor activity and transcription cis-regulatory region binding activity. Involved in in utero embryonic development and negative regulation of transcription by RNA polymerase II. Acts upstream of or within cellular response to leukemia inhibitory factor; embryonic placenta development; and trophectodermal cell differentiation. Predicted to be located in chromatin. Predicted to be part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; peripheral nervous system; and sensory organ. Human ortholog(s) of this gene implicated in vitiligo. Orthologous to human FOXD3 (forkhead box D3). [provided by Alliance of Genome Resources, Apr 2022]
