Summary: Enables DNA-binding transcription factor activity, RNA polymerase II-specific and cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II; regulation of R7 cell differentiation; and regulation of compound eye cone cell fate specification. Located in nucleus. Is expressed in several structures, including embryonic supraesophageal neuromere; imaginal disc; neurogenic region; sense organ; and sensory nervous system primordium. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia; congenital hypothyroidism (multiple); focal segmental glomerulosclerosis 7; renal Wilms' tumor; and renal coloboma syndrome. Orthologous to human PAX2 (paired box 2); PAX5 (paired box 5); and PAX8 (paired box 8). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Loss of Bar from the undifferentiated retinal precursor cells leads to ectopic expression of Prospero and dPax2, two transcription factors essential for cone cell specification, resulting in excess cone cell differentiation.
Title: Bar represses dPax2 and decapentaplegic to regulate cell fate and morphogenetic cell death in Drosophila eye.
Data demonstrate that early activation of D-Pax2 in the sensory organ lineage and its maintenance in the trichogen and thecogen cells are governed by separate enhancers.
Title: Discrete regulatory regions control early and late expression of D-Pax2 during external sensory organ development.
examine in detail the structure and function of sparkling, a Notch- and EGFR/MAPK-regulated, cone cell-specific enhancer of the Pax2 gene, in vivo
Title: Structural rules and complex regulatory circuitry constrain expression of a Notch- and EGFR-regulated eye enhancer.
Data show that D-Pax2 plays a significant role in lens development through regulation of the Crystallin gene and because Crystallin is also expressed in D-Pax2(+) cells in the external sensory organs.
Title: The transcription factor D-Pax2 regulates crystallin production during eye development in Drosophila melanogaster.
The ectopic cell death evident in D-Pax2 mutants appears to arise from the cell fate transformation of cone cells into secondary pigment cells, either autonomously or as a result of defective signalling.
Title: Mutations in lozenge and D-Pax2 invoke ectopic patterned cell death in the developing Drosophila eye using distinct mechanisms.
Mutational inactivation of otd/Otx2 and unpg/Gbx2 result in the loss or misplacement of the brain-specific expression domains of Pax2/5/8 and Hox genes.
