Gene Snapshot
araucan (ara) encodes a homeodomain-containing protein of the TALE subfamily and one of the three components of the Iroquois gene complex. ara product acts as a transcriptional regulator to control territorial and cell fate specification, cell sorting behaviour and pattern formation. It also plays a transcription independent cell-autonomous role in cell proliferation control. [Date last reviewed: 2018-09-20]

Gene Group Membership
TALE HOMEOBOX TRANSCRIPTION FACTORS -
TALE homeobox transcription factors are sequence-specific DNA binding proteins that regulate transcription. These proteins are characterized by an atypical homeodomain that possesses a three amino acid insertion in the first loop. (Adapted from FBrf0232555 and PMID:18797923).
UniProt Contributed Function Data
Controls proneural and vein forming genes. Positive transcriptional controler of AC-SC (achaete-scute). May act as an activator that interacts with the transcriptional complex assembled on the AC and SC promoters and participates in transcription initiation.

      The acquisition of lateral transverse muscle fate requires the repression mediated by ara/caup of other muscle identity genes (such as slou and vg).
      RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
      Iroquois complex genes (ara, caup and mirr) are required for the specification of dorsal head structures.
      The localised expression of the three genes of the iroquois complex - IRO-C (ara, caup and mirr) specifies the identity of dorsal cells in the eye. Juxtaposition of IRO-C-expressing and non-expressing cells forms a straight border that promotes growth and serves as a pattern-organising centre in the eye disc.
      The genes of the Iroquois complex (ara, caup and mirr) are necessary for notum specification. The Iro-C genes establish a signalling system that appears to organize development in the notum and dorsal wing hinge (tegula and sclerite) territories.
      When the Iroquois complex is absent, notum cells are transformed into hinge (tegula and sclerite) cells.
      A member of the IRO-C (Iroquois complex).
      The genes of the IRO-C are coordinately regulated and implicated in similar developmental processes. They are regulated in the eye by the Pc-group and trx-group genes, but not by classical modifiers of position effect variegation. Ventral silencing of the whole IRO-C in the eye occurs at the level of chromatin structure in a manner similar to that of the homeotic gene complexes, perhaps by local compaction of the region into a heterochromatin-like structure involving Pc-group products.
      The ara gene maps to the Iroquois complex and contributes to the prepattern that regulates expression of ac-sc complex genes and rho. ara is a positive, direct regulator of the ac-sc genes.
      Gene titration method has been used to search for genes involved in the determination of sense organs. A mutation of ara and caup (formerly iro) demonstrates an interaction with Df(4)M101-62f, a chromosome known to alter the development of the PNS.
      In mutants for the Iroquois gene complex, two lateral bands of the notum are completely devoid of sense organs.
      Origin and Etymology
      Discoverer
      Etymology
      The "ara" gene is named after the Araucanian American-Indian tribe.
      The 'Iroquois' gene complex is named after the native American Iroquois tribe, also called Mohawks, which shaved all but a medial stripe of hairs on the head.
      "Iroquois" is the name given to the gene complex by analogy with the American tribe that have a haircut ascribed to the Mohawk nation.
