General description

POU domain class 5 transcription factor 1 (POU5F1) is also termed as OCT4. It is a transcription factor. OCT4 codes for three isoforms, such as OCT4A, OCT4B and OCT4B1. These isoforms are produced by alternative splicing. The OCT4 gene consists of 7 exons. This gene is located on human chromosome 6. OCT4A and OCT4B are located in the nucleus and cytoplasm respectively.

Immunogen

synthetic peptide corresponding to an internal sequence of human Oct 3/4. This sequence is 84% identical in mouse and 94% identical in rat.

Application

Anti-Oct 3/4 antibody produced in rabbit has been used in immunocytochemistry and immunofluorescence staining.

Biochem/physiol Actions

Oct 3/4 maintains developmental potency and governs distinct fates of embryonic stem cells. A moderate increase in expression causes differentiation into primitive endoderm and mesoderm. In contrast, repression of Oct 3/4 stimulates loss of pluripotency and dedifferentiation to trophectoderm. POU domain class 5 transcription factor 1 (POU5F1) serves as a master regulator of pluripotency in embryonic stem cells. It is one of the reprogramming factors, that is highly essential for generating induced pluripotent stem cells.

Physical form

solution in phosphate buffered saline, containing 0.02% sodium azide.
