PHD Finger Protein 8 (PHF8) Antibody

Background

PHF8 is a histone demethylase containing a PHD finger domain that recognizes H3K4me3 and demethylates repressive marks such as H3K9me2/1 to activate transcription. It plays a role in gene regulation during cell cycle progression, neuronal development, and DNA damage repair by promoting chromatin accessibility. PHF8 is expressed in neural tissues and contributes to neurogenesis, synaptic plasticity, and cognitive function. Mutations in PHF8 are associated with X-linked intellectual disability and cleft lip/palate syndromes, where impaired histone demethylation leads to defective gene expression during development. Dysregulation of PHF8 is also implicated in cancer, where it promotes tumor growth and proliferation through transcriptional activation of oncogenes. Knockdown studies demonstrate impaired DNA repair, cell cycle arrest, and defects in neuronal differentiation, highlighting its critical role in histone demethylation, chromatin regulation, and developmental processes.
