Transcription factor. Binds optimally to the DNA consensus sequence 5'-YYTAATGRTTTTY-3'. May control the expression of neural adhesion molecules such as L1 or Ng-CAM during embryonic development of both the central and peripherical nervous system. May be involved in controlling adhesive processes in keratinizing epithelia (By similarity). Highly expressed in adult salivary gland and at much lower levels in mammary gland, kidney and placenta. Belongs to the BAR homeobox family. Truncated N-terminus. Truncated N-terminus.
