Description

Exhibits cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including pharyngeal system development; regulation of bone mineralization; and sprouting angiogenesis. Human ortholog(s) of this gene implicated in Saethre-Chotzen syndrome; Sweeney-Cox syndrome; acrocephalosyndactylia; and craniosynostosis. Is expressed in several structures, including brain; cardiovascular system; cranial vault; mesoderm; and pharyngeal arch. Orthologous to human TWIST1 (twist family bHLH transcription factor 1).
