Zinc finger protein 57 (ZNF57) is a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein family, characterized by tandem Cys₂His₂ zinc finger motifs that mediate sequence-specific DNA binding. These proteins are critical regulators of gene expression, often acting as transcription factors or epigenetic modifiers by recruiting chromatin-remodeling complexes. ZNF57. encoded by the ZNF57 gene on human chromosome 19q13.43. is notable for its preferential expression in testis, suggesting potential roles in germ cell development or spermatogenesis. The protein contains a KRAB domain at its N-terminus, which typically interacts with transcriptional co-repressors to suppress target gene activity, and multiple zinc finger repeats for DNA recognition.
Recombinant human ZNF57 protein is engineered using heterologous expression systems (e.g., E. coli, HEK293. or insect cells) to enable functional studies. Its production involves cloning the coding sequence into expression vectors, followed by purification via affinity tags (e.g., His-tag) and chromatography. Researchers utilize recombinant ZNF57 to investigate its DNA-binding specificity, interactions with partner proteins like TRIM28/KAP1. and roles in cellular processes such as differentiation or oncogenesis. Structural studies of this protein contribute to understanding zinc finger-mediated gene regulation mechanisms and potential therapeutic targeting. Current research also explores its possible involvement in diseases linked to zinc finger protein dysregulation, including cancers and developmental disorders.
