Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including embryonic skeletal joint development; nervous system development; and retina morphogenesis in camera-type eye. Predicted to be active in nucleus. Is expressed in several structures, including head; interhyal-hyosymplectic joint; nervous system; neural keel; and neural plate.

What's a GeneRIF?

These observations suggest a different regulatory mechanism on bhlhe22 expression by smarca4 and irx7.
Title: Irx7, a Smarca4-regulated gene for retinal differentiation, regulates other genes controlled by Smarca4 in zebrafish retinas.
The retinal lamination issue in the Irx7-deficient retinas is likely caused by the attenuation of the neurite outgrowth
Title: The expression of irx7 in the inner nuclear layer of zebrafish retina is essential for a proper retinal development and lamination.
Data show that Irx7 and Irx1b are required for the proper formation and specification of rhombomeres 1 to 4, and that Irx7 functionally interacts with Meis1.1 to activate the expression of anterior hindbrain markers, such as krox20.
Title: A functional interaction between Irx and Meis patterns the anterior hindbrain and activates krox20 expression in rhombomere 3.
iro7 has a dual function in the hindbrain of the zebrafish embryo: it is required for the proper positioning of the prospective r4/r5 boundary and it promotes neurogenesis in the anterior hindbrain
Title: The zebrafish Iroquois gene iro7 positions the r4/r5 boundary and controls neurogenesis in the rostral hindbrain.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
