PRDM4 (PR/SET domain 4) is a transcription factor localized to the nucleus through mechanisms involving zinc fingers 1, 2, 5, and 6 1, where it regulates gene expression through RNA polymerase II-mediated transcription. The protein functions in cell differentiation and proliferation control across multiple tissues including brain, corneal endothelium, and adipose tissue 2, 3. In cancer biology, PRDM4 exhibits context-dependent roles: it functions as a YAP co-activator to promote cell invasion by inducing leukocyte-specific integrin β2 (ITGB2) expression in metastatic prostate cancer 4, yet acts as a tumor suppressor in cervical carcinoma by transactivating PTEN expression to inactivate the PI3K/AKT proliferation pathway, inducing G0/G1 cell cycle arrest 5. PRDM4 maps to chromosome 12-q24.1, a known tumor suppressor locus 6. The gene is expressed in neural stem cells during development 7 and can be therapeutically induced by small molecules like butein to promote white adipose tissue browning and thermogenesis 3. PRDM4 has been identified as a genetic marker associated with psychological endurance threshold 8, though this finding requires further validation.
