Zc3Hav1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Official Symbol: ZC3HAV1 [1]
Official Full Name: Zinc Finger CCCH-Type Antiviral Protein 1 [2]
Location: Chromosome 7q34 [3]
Gene ID: 92075
Zinc Finger CCCH-Type Antiviral Protein 1 (ZC3HAV1), also known as ZAP, is a host restriction factor that inhibits viral replication by degrading viral mRNAs and blocking viral gene expression. It plays an important role in the innate immune response to retroviruses, flaviviruses, and other viruses.
The ZC3HAV1 gene spans approximately 48 kb and consists of 8 exons. It encodes a protein of 707 amino acids with multiple zinc finger domains.
ZC3HAV1 contains:
ZC3HAV1 is an antiviral protein that specifically targets viral mRNAs for degradation:
