Biology:Iroquois homeobox factor

From HandWiki
Short description: Protein family

Iroquois homeobox factors are a family of homeodomain transcription factors that play a role in many developmental processes.[1][2] The loci were named for the flies carrying mutations in one of these genes, which are devoid of all bristles in the lateral part of the notum, leaving only a median stripe of bristles, similar to the Iroquois tribes which shaved all but a medial stripe of hairs on the head.[3]

Human genes that encode Iroquois homeobox factors include:[2]

  • IrxA sub-group: IRX1, IRX2, IRX4
  • IrxB sub-group: IRX3, IRX5, IRX6
  • Iroquois-like gene: MKX
