GeneDescription It is a homeodomain transcription factor of the POU family. It is known to be inxolved in the self renewal of undifferentiated embryonic stem cells.
GeneFunction Parvin et al. (2008) found that the main regulatory element to which pou5f1 binds reside in the proximal upstream of the DNA sequence from -2.2 to -0.12 kb. They further performed the electrophoretic gel mobility shift assay which revealed that there are four functional octamer sequences that can associate with zebrafish pou5f1. They had also shown that the four octamer sequences operate in a co-operative manner to drive the expression of pou5f1 in the mid/hindbrain.They also identified the retinoic acid –responsive elements in this proximal region, which was required to repress transcription.

Lachnit et al. ( 2008) analyzed in detail the gastrulation defects present in the zebrafish pou5f1 deficient maternal and zygotic spiel ohne grenzen mutant embryos. These defects are manifested by a severe delay in epiboly progression. They found that all three embryonic lineages in mutant embryos behaved abnormally during epiboly. They found that the yolk cell forms an altered array of cortical microtubules and F-actin, the enveloping layer in delayed and the deep layer cells are non-autonomously affected in their mobility.

Reim et al. (2006) had shown that the embryos that are genetically depleted of pou2 function exhibited severe Dorsoventral patterning defects and an arrest in epiboly.

Reim et al. (2004) had reported that pou5f1 is involved in the formation of the endoderm. They had further shown that embryos that are devoid of the pou5f1 function lacked endodermal precursors. They had further shown that pou5f1 acts in early endodermal precursors.
