ZKSCAN1. a member of the zinc finger and SCAN domain-containing (ZKSCAN) protein family, functions as a transcription regulator involved in diverse cellular processes. Structurally, it contains an N-terminal SCAN domain, which mediates protein-protein interactions, and multiple C-terminal C2H2-type zinc finger motifs that enable sequence-specific DNA binding. Predominantly localized in the nucleus, ZKSCAN1 acts as a transcriptional repressor by binding to promoter regions of target genes, influencing chromatin remodeling and gene silencing. Studies suggest its role in modulating autophagy, cell proliferation, and apoptosis. For instance, ZKSCAN1 has been implicated in suppressing autophagosome formation by regulating autophagy-related gene expression, with altered activity observed in cancer and neurodegenerative diseases.
Recombinant human ZKSCAN1 protein is engineered using heterologous expression systems (e.g., Escherichia coli, mammalian cells) to study its molecular mechanisms and interactions. This purified protein serves as a tool for in vitro DNA-binding assays, chromatin immunoprecipitation, and functional studies exploring its regulatory networks. Research highlights its potential as a therapeutic target, particularly in cancers where dysregulated autophagy contributes to tumor survival. However, its full physiological context and downstream effectors remain under investigation, necessitating further studies to elucidate its role in health and disease.
