ZBTB37 is a zinc finger and BTB domain-containing transcription factor that functions as a sequence-specific DNA-binding transcription repressor of RNA polymerase II 1. The protein likely negatively regulates transcription and participates in chr1-associated regulatory processes, with potential roles in immune system regulation and cytokine production based on GO annotations. Mechanism: ZBTB37 contains domains characteristic of BTB/POZ-family transcriptional regulators, enabling sequence-specific double-stranded DNA binding and transcriptional repression activity at RNA polymerase II cis-regulatory regions. Disease Relevance: ZBTB37 expression changes have been implicated in severe hand, foot, and mouth disease (HFMD) caused by EV71 infection in children. A machine learning model incorporating ZBTB37 expression levels among five biomarkers achieved 91.3% ROC-AUC in predicting severe HFMD severity 2. Additionally, ZBTB37 was identified as a hub transcription factor in lung adenocarcinoma lncRNA-transcription factor networks with potential prognostic significance 1. Clinical Significance: ZBTB37 represents a potential biomarker for early HFMD severity prediction, enabling rapid patient stratification (2-3 hours) that could guide clinical management decisions 2. The gene's association with immune response suppression during severe viral infection and its regulatory role in transcriptional networks suggest therapeutic potential.
