Summary: Enables several functions, including DNA-binding transcription factor activity; chromatin binding activity; and protein heterodimerization activity. Involved in nucleosome organization. Acts upstream of with a positive effect on cell dedifferentiation. Acts upstream of or within several processes, including brain development; embryonic morphogenesis; and regulation of gene expression. Predicted to be located in nucleus. Is expressed in several structures, including blastoderm; blastodisc; ectoderm; gonad; and hindbrain neural keel. Human ortholog(s) of this gene implicated in embryonal carcinoma and seminoma. Orthologous to human POU5F1 (POU class 5 homeobox 1); POU5F1B (POU class 5 homeobox 1B); and POU5F2 (POU domain class 5, transcription factor 2). [provided by Alliance of Genome Resources, Nov 2024]

During gastrulation, the expression of the Oct4-related PouV gene pou5f3 (also called pou2), which is widely observed at earlier stages, was rapidly localized to an array of isolated spotted domains, each of which coincided with individual proneural clusters. These results suggest that pou5f3 promotes early neurogenesis in proneural clusters, but negatively regulates later neurogenesis.
Title: Involvement of an Oct4-related PouV gene, pou5f3/pou2, in neurogenesis in the early neural plate of zebrafish embryos.
Results found that Oct4 is rapidly induced during zebrafish retina regeneration. It mediates a gene regulatory network during Muller glia (MG) reprogramming. The tudy reveals unique mechanistic involvement of Oct4, during MG reprogramming and cell cycle exit in zebrafish, which may also account for the inefficient retina regeneration in mammals.

Western blot analysis were conducted on developing hatchlings with Oct4 antibody and at 13.6 and 21.6mugL(-1)dose,it showed over expression elucidating stimulatory role of nanosilver. In silico analysis depicted a firm interaction of nanosilver with Oct4 revealing their key role in growth stimulation of developing embryos.

The authors show, at single-cell resolution in vivo, that Pou5f3 complexes with Nanog to pattern mesendoderm differentiation at the blastula stage.

Data suggest that, in developing gastrula, Znfl1 controls developmental gene expression of Hoxb1b in embryonic posterior neuroectoderm by acting upstream of Pou5f3 and Sall4; these proteins appear to be involved in neurogenesis. (Znfl1 = zinc finger-like gene 1; Hoxb1b = homeobox B1b protein; Pou5f3 = POU domain class 5 transcription factor 3; Sall4 = spalt-like transcription factor 4)

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.
