Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including circulatory system development; endothelial cell differentiation; and reproductive structure development. Located in nucleus. Is expressed in several structures, including genitourinary system; intestine; limb; limb bud; and nervous system. Used to study hand-foot-genital syndrome. Human ortholog(s) of this gene implicated in Guttmacher syndrome and hand-foot-genital syndrome. Orthologous to human HOXA13 (homeobox A13). [provided by Alliance of Genome Resources, Apr 2022]
