ZNF291. also known as ZNF469 or ZNFN1A1. is a human protein belonging to the zinc finger protein family characterized by conserved Cys2-His2 (C2H2) zinc finger motifs. This 731-amino-acid protein contains 18 consecutive zinc finger domains in its C-terminal region, suggesting DNA-binding properties potentially involved in transcriptional regulation. As a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein subfamily, ZNF291 is hypothesized to function as a transcription factor through KRAB-mediated recruitment of chromatin-modifying complexes.
Genomic studies locate the ZNF291 gene on chromosome 1p36.13. a region associated with developmental disorders and cancer. While its precise biological functions remain under investigation, emerging evidence implicates ZNF291 in multiple cellular processes. RNA-seq data indicate its expression across various tissues, with relative abundance in immune cells and reproductive organs. Experimental studies suggest potential roles in cell cycle regulation, differentiation, and tumorigenesis, with altered expression patterns observed in colorectal cancer and hematological malignancies.
Recombinant ZNF291 protein is typically produced using bacterial (E. coli) or mammalian expression systems, often fused with tags (e.g., His-tag) for purification and detection. Current research focuses on mapping its DNA-binding specificity through techniques like protein-binding microarrays and elucidating interactions with regulatory proteins. As an understudied protein in the large zinc finger family, ZNF291 represents a potential therapeutic target and tool for synthetic biology applications, warranting further characterization of its structural and functional properties.
