Phospho-OCT4(S236) antibody is a specialized tool used to detect the phosphorylated form of OCT4 at serine residue 236 (S236). OCT4 (encoded by *POU5F1*) is a transcription factor critical for maintaining pluripotency in embryonic stem cells (ESCs) and primordial germ cells. Post-translational modifications, including phosphorylation, regulate OCT4's stability, subcellular localization, and interactions with co-factors. Phosphorylation at S236 has been implicated in modulating OCT4’s transcriptional activity and its role in self-renewal versus differentiation. Studies suggest that S236 phosphorylation may promote pluripotency by stabilizing OCT4 or enhancing its nuclear retention, though its precise mechanistic role remains under investigation.
This antibody is widely employed in stem cell research, cancer biology, and regenerative medicine to study OCT4 dynamics in cellular reprogramming, tumorigenesis, and differentiation. It is validated for techniques like Western blotting, immunofluorescence, and immunohistochemistry, often in models such as induced pluripotent stem cells (iPSCs) or germ cell tumors. Dysregulation of phosphorylated OCT4 has been linked to cancers, including testicular germ cell tumors, where its aberrant expression may drive malignancy. Researchers also use this antibody to explore signaling pathways (e.g., Akt/PKB kinase) that regulate OCT4 phosphorylation, offering insights into therapeutic targeting of stem-like cancer cells or improving reprogramming efficiency. Specificity validation via knockout controls or phosphatase treatment is recommended to confirm signal accuracy.
