NTERA-2 cl.D1 human embryoid carcinoma cells were fixed with 4% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for 10 minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2.5 µg/ml anti-human Oct4 (Oct3) (clone 3A2A20) Alexa Fluor® 594 (red) in blocking buffer overnight at 4°C and followed by Alexa Fluor® 488 Phalloidin (green) staining for 20 minutes at 4°C. Nuclei were counterstained with DAPI (blue). The image was captured with a 40X objective.

Description

Oct4 (Octamer binding transcription factor 4) is an important marker of the undifferentiated state and central regulator of pluripotency in ES cells. When embryonic stem cells are triggered to differentiate, Oct4 is downregulated, thus providing a model for the early events linked to somatic differentiation in the developing embryo. Oct4 is a nuclear protein, with a predicted molecular weight of 39 kD.

Antigen Details

Structure
Belongs to the POU transcription factor family, predicted molecular weight of 39 kD
Distribution

Nuclear protein, expressed in undifferentiated embryonal carcinoma (EC) cells, embryonic stem (ES) cells and embryonic germ (EG) cells

Function
Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Oct4 is a prime candidate for an early developmental control gene. It also is an important marker of the undifferentiated state and central regulator of pluripotency in ES cells.
Interaction
SOX2, SOX8, SOX10, androgen receptor, and ETS2
