ZC3HAV1 (Zinc Finger CCCH-Type Antiviral Protein 1), also known as ZAP or PARP13. is a human protein encoded by the ZC3HAV1 gene. It belongs to the poly(ADP-ribose) polymerase (PARP) family but lacks catalytic activity typical of other PARPs due to evolutionary mutations in its PARP domain. Structurally, it contains four N-terminal CCCH-type zinc finger motifs critical for RNA binding and a C-terminal PARP-like domain involved in protein interactions.
ZC3HAV1 is a key innate antiviral factor that restricts a broad spectrum of viruses, including retroviruses, alphaviruses, and filoviruses. It selectively binds to viral RNAs containing CpG-rich regions, triggering their degradation via recruitment of exosome components and suppressing translation through interactions with translation machinery. This activity is enhanced by its splice variants, particularly the shorter ZAP-S isoform.
Recombinant ZC3HAV1 protein is produced using expression systems like E. coli or mammalian cells, often fused with tags (e.g., His-tag) for purification via affinity chromatography. Its recombinant form enables studies on host-virus interactions, antiviral mechanisms, and therapeutic development. Beyond virology, ZC3HAV1 is studied in cancer research due to its reported tumor-suppressive effects, potentially linked to apoptosis regulation and inhibition of oncogenic viral replication. Its dual roles in antiviral defense and cellular homeostasis make it a multifunctional protein of significant biomedical interest.
