Hoxb9 - homeobox B9

Contributes to RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including embryonic skeletal system development; mammary gland development; and positive regulation of transcription by RNA polymerase II. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including early embryo; embryo mesenchyme; genitourinary system; gut; and nervous system. Orthologous to human HOXB9 (homeobox B9). [provided by Alliance of Genome Resources, Apr 2022]
