Zinc finger protein 143 (ZNF143), also known as human homolog of Xenopus Staf, is a transcription factor encoded by the ZNF143 gene in humans. Structurally, it contains C2H2-type zinc finger motifs that enable sequence-specific DNA binding, along with nuclear localization signals directing its function in gene regulation. ZNF143 modulates the expression of target genes by binding to promoter or enhancer regions, often interacting with other transcriptional regulators and chromatin-modifying enzymes. It has been implicated in diverse cellular processes, including cell cycle progression, apoptosis, differentiation, and embryonic development.
Studies highlight its dual regulatory roles: ZNF143 activates genes involved in RNA processing, ribosome biogenesis, and mitochondrial function, while repressing others through epigenetic mechanisms. Its interaction with non-coding RNAs and participation in chromatin looping further underscore its complexity in 3D genome organization. Clinically, ZNF143 dysregulation is linked to cancers, where it may act as either an oncogene or tumor suppressor depending on cellular context. Elevated expression has been observed in hepatocellular carcinoma and colorectal cancer, correlating with metastasis and poor prognosis.
Recent research also explores its potential as a therapeutic target. Despite progress, its context-dependent mechanisms and tissue-specific functions remain under investigation, emphasizing its importance in both fundamental biology and disease pathology.
