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 nervous system development; regulation of respiratory gaseous exchange by nervous system process; and respiratory gaseous exchange by respiratory system. Located in nucleus. Is expressed in several structures, including branchial arch; central nervous system; ganglia; genitourinary system; and sensory organ. Used to study congenital central hypoventilation syndrome. Orthologous to human TLX3 (T cell leukemia homeobox 3). [provided by Alliance of Genome Resources, Dec 2024]

Tlx3 controls the development of C-low threshold mechanoreceptors.
Title: Tlx3 controls the development of C-low threshold mechanoreceptors.
Ectopic expression of TLX3 alone caused partially penetrant leukemia. TLX3 expression and loss of PHF6 combined caused fully penetrant early-onset leukemia.
Title: PHF6 regulates hematopoietic stem and progenitor cells and its loss synergizes with expression of TLX3 to cause leukemia.
These results demonstrate a novel role for Tlx3 and indicate that Pax6-Tlx3 expression and interaction is part of a region specific regulatory network in cerebellum and its deregulation during development could possibly lead to Autistic spectral disorders (ASD).
Title: Regulation of Tlx3 by Pax6 is required for the restricted expression of Chrnα3 in Cerebellar Granule Neuron progenitors during development.
Tlx3 promotes glutamatergic neuronal subtype specification through direct interactions with the chromatin modifier CBP.
Title: Tlx3 promotes glutamatergic neuronal subtype specification through direct interactions with the chromatin modifier CBP.
Tlx3 uses distinct mechanisms to tightly modulate Prrxl1 activity, either by controlling its transcriptional levels or by increasing Prrxl1 phosphorylation state.

The tlx2 knockout mice failed to exhibit escape response evoked by dynamic mechanical stimuli but retained the ability to sense innocuous cooling and/or warm and development of a subset of excitatory neurons located in laminae I and II was impaired.

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.
