Zinc finger protein 343 (ZNF343), also known as Zfp343 in some species, is a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein family, characterized by its C2H2-type zinc finger motifs. These proteins typically function as transcription regulators by binding to specific DNA sequences. ZNF343 is evolutionarily conserved and plays a role in cellular processes such as proliferation, differentiation, and tumorigenesis. Studies suggest its involvement in modulating chromatin structure and gene expression through interactions with epigenetic modifiers or transcriptional machinery. Notably, ZNF343 has been implicated in cancer biology, where it may act as either an oncogene or tumor suppressor depending on cellular context, though its precise mechanisms remain under investigation.
Recombinant human ZNF343 protein is engineered for experimental studies, often produced in bacterial or mammalian expression systems with tags (e.g., His-tag) for purification and detection. It enables in vitro analyses of DNA-binding properties, protein-protein interactions, and functional assays to elucidate its regulatory roles. Researchers utilize this tool to explore ZNF343's participation in pathways like Wnt/β-catenin or p53 signaling, which are critical in development and disease. Dysregulation of ZNF343 has been observed in malignancies (e.g., glioblastoma, colorectal cancer) and neurological disorders, highlighting its therapeutic potential. Current challenges include clarifying its target genes, post-translational modifications, and tissue-specific functions, driving ongoing studies to map its biological significance in health and disease.
