ZRF1 (Zuotin-Related Factor 1), also known as DNAJC2 or MPP11. is a molecular chaperone protein belonging to the HSP40/DNAJ family. It was initially identified through its interaction with the ribosome-associated complex (RAC) and its homology to zuotin, a yeast protein involved in chromatin remodeling and stress response. ZRF1 plays dual roles in cellular processes, functioning as both a co-chaperone and an epigenetic regulator. Structurally, it contains a conserved J-domain that mediates interactions with heat shock protein 70 (HSP70) to facilitate protein folding, alongside zinc finger motifs and a SANT domain that enable chromatin binding.
In stem cell biology, ZRF1 is critical for maintaining pluripotency by repressing Polycomb-repressed genes during differentiation. It achieves this by displacing Polycomb repressive complex 1 (PRC1) from chromatin, acting as a "catalytic" factor in transcriptional reprogramming. Paradoxically, ZRF1 also exhibits oncogenic properties in certain cancers, where it stabilizes oncoproteins like MYC and promotes tumor cell survival through proteostasis regulation. Recombinant ZRF1 protein is commonly produced in Escherichia coli or mammalian expression systems for functional studies. Its applications span investigating protein folding mechanisms, stem cell differentiation pathways, and cancer biology. Recent research highlights its potential as a therapeutic target, particularly in malignancies reliant on MYC signaling or epigenetic dysregulation. The protein's bifunctional nature—bridging protein quality control and epigenetic regulation—makes it a unique subject in both basic molecular research and translational medicine.
