Zinc finger protein 271 (ZNF271), a member of the Krüppel-associated box zinc finger protein (KRAB-ZFP) family, is a human transcription factor implicated in gene regulation. Structurally, it contains multiple C2H2-type zinc finger motifs at its C-terminus, which enable sequence-specific DNA binding, and a KRAB domain at the N-terminus, known for recruiting chromatin-modifying complexes to mediate transcriptional repression. The KRAB-ZFP family, including ZNF271. is involved in silencing transposable elements and maintaining genome stability during evolution.
Recombinant ZNF271 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains its functional domains and is widely used to study DNA-protein interactions, epigenetic regulation, and gene silencing mechanisms. Studies suggest its potential role in cell differentiation, proliferation, and tumorigenesis, though its precise biological targets remain under investigation.
Research challenges include elucidating its binding specificity across diverse genomic loci and understanding how its regulatory networks intersect with diseases. Recombinant ZNF271 serves as a critical tool for *in vitro* assays, structural studies, and high-throughput screening to decode its molecular functions. Advances in protein engineering and CRISPR-based technologies have further enabled functional studies, though the protein’s complex domain architecture necessitates careful optimization in experimental design. Overall, ZNF271 exemplifies the intricate interplay between zinc finger proteins and epigenetic regulation in human biology.
