What is the importance of Oct4?
Oct4 mainly functions through the activation of pluripotency-associated and self-renewal-associated genes, while simultaneously repressing genes that promote differentiation, in coordination with other pluripotency factors and coregulators.
Is Oct4 an oncogene?
Octamer-binding transcription factor 4 (OCT4) is a key regulatory gene that maintains the pluripotency and self-renewal properties of embryonic stem cells. Although there is emerging evidence that it can function as oncogene in several cancers, the role in mediating cervical cancer remains unexplored.
What does Oct4 bind to?
OCT4 binds distal regulatory sites in mouse embryonic stems cells to shape chromatin accessibility. During somatic cell reprogramming, exogenous OCT4 is proposed to function as a pioneer transcription factor that can bind to its sequence motifs in inaccessible regions of chromatin.
Is Oct4 a gene?
The Oct4 protein, encoded by the Pou5f1 gene was the very first master gene, discovered 25 years ago, to be absolutely required for the stemness properties of murine and primate embryonic stem cells.
What is the function of Oct-4?
Oct-4 is a homeodomain transcription factor of the POU family. It is critically involved in the self-renewal of undifferentiated embryonic stem cells. As such, it is frequently used as a marker for undifferentiated cells.
What stains Sox2?
Sox2 is known to play an important role in maintaining the totipotency and self-renewal of embryonic stem cells. Indirect immunofluorescent staining of Sox2-overexpressing cells showed strong nuclear and diffuse cytoplasmic immunoreactivity for Sox2 in the antichicken Sox2 antibody-staining cells.
Is Oct 4 gene constitutively expressed?
Oct-4 (octamer-binding transcription factor 4), also known as POU5F1 (POU domain, class 5, transcription factor 1), is a protein that in humans is encoded by the POU5F1 gene. Oct-4 is a homeodomain transcription factor of the POU family….Oct-4.

What kind of gene is Sox2?
SOX2 (SRY-Box Transcription Factor 2) is a Protein Coding gene. Diseases associated with SOX2 include Microphthalmia, Syndromic 3 and Septooptic Dysplasia. Among its related pathways are Oct4 in Mammalian ESC Pluripotency and Cytokine Signaling in Immune system.
What does the Oct 4 Gene do?
Is Sox2 a gene?
The SOX2 gene provides instructions for making a protein that plays a critical role in the formation of many different tissues and organs during embryonic development. The SOX2 protein is especially important for the development of the eyes.
