Summary: Enables HMG box domain binding activity and sequence-specific DNA binding activity. Involved in several processes, including metanephric nephron epithelium development; negative regulation of apoptotic process; and regulation of DNA-templated transcription. Acts upstream of or within several processes, including forebrain development; positive regulation of transcription by RNA polymerase II; and urea transmembrane transport. Located in nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; phalanx; and sensory organ. Orthologous to human POU3F3 (POU class 3 homeobox 3).

The results of the present study confirm the important function of POU3F3 in nephron patterning, especially in development of the the Thick Ascending Limb of the Loop of Henle. Missense Mutation of POU Domain Class 3 Transcription Factor 3 in Pou3f3L423P Mice Causes Reduced Nephron Number and Impaired Development of the Thick Ascending Limb of the Loop of Henle.

results suggest that a mutually repressive mechanism exists between Brn1/2 and Rorb expression and that the established expression of Brn1/2 and Rorb further specifies those neurons into L2/3 and L4, respectively, during UCP maturation

Brn1 predominantly forms homomdimers on MORE cis elements in NS5 mouse neural stem cells
Title: Selective influence of Sox2 on POU transcription factor binding in embryonic and neural stem cells.
Onset of Pou3f3 expression occurs in ventricular zone progenitors, and that Pou3f3 subsequently label neural progeny switching from deep-layer Ctip2+ identity to Satb2+ upper-layer fate as they migrate to proper superficial positions.
Title: POU-III transcription factors (Brn1, Brn2, and Oct6) influence neurogenesis, molecular identity, and migratory destination of upper-layer cells of the cerebral cortex.
Data show that Oct-6 normally represses Wnt1 expression in the early diencephalon and replacement by Brn-1 as a weaker inhibitor is no longer sufficient to maintain the necessary level of repression in the mouse mutant.
Title: Replacement of related POU transcription factors leads to severe defects in mouse forebrain development.
Sox2 and SF1 may mediate basal nestin expression in undifferentiated cells, whereas Sox2, Brn1, and Brn2 bind to the enhancer in neural progenitor cells.
Title: Different transcription factors regulate nestin gene expression during P19 cell neural differentiation and central nervous system development.
These results suggest that Brn1 is essential for both the development and function of the nephron in the kidney.

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.
