PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N terminal polyalanine tract
  • a nuclear localization signal (NLS) overlapping with the homeodomain (helix-turn-helix motif)
  • a highly conserved poline/serine/threonine domain, 3' of the homeo domain
    • HOMOLOGY
    interspecies ortholog to murine Barx1
    Homologene
    FAMILY
  • BAR homeobox family
    • CATEGORY transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus
    basic FUNCTION
  • transcriptional activator/repressor or both
  • as in the developing stomach, but distinct from the spleen, BARX1 control of thoracic foregut specification and tracheo-esophageal septation is tightly associated with down-regulation of adjacent Wnt pathway activity
  • changes in BARX1 function likely in early vertebrates were among the key innovations fostering the evolution of skeletal joints
    • CELLULAR PROCESS nucleotide, transcription, regulation

  • potent BARX1 functions in intestinal rotation and stomach myogenesis occur through ISL1, PITX1, SIX2 and PITX2, intermediary transcription factors
