ZCCHC11. also known as human terminal nucleotidyltransferase 1 (TENT1), is a RNA-binding protein belonging to the CCCH-type zinc finger protein family. It contains a characteristic CCHC zinc finger motif involved in nucleic acid interactions and a non-canonical poly(A) polymerase (PAP) domain. This protein plays dual roles in RNA metabolism: as a cytoplasmic poly(A) polymerase, it selectively extends poly(A) tails of specific mRNAs to enhance their stability and translation efficiency, while also functioning as a deadenylase to remove poly(A) sequences from other RNA targets. Notably, ZCCHC11 has been implicated in post-transcriptional regulation of antiviral immune response genes and retrotransposon elements.
Recombinant human ZCCHC11 protein is typically produced through heterologous expression systems (e.g., E. coli or mammalian cells) for functional studies. Its biochemical characterization has revealed moonlighting enzymatic activities modulated by interacting partners like Roquin-1. Current research focuses on its involvement in immune regulation, cancer biology (particularly in hepatocellular carcinoma), and viral-host interactions, with emerging evidence suggesting roles in maintaining genome stability through LINE-1 retrotransposon silencing. Structural studies aim to decipher how its dual enzymatic activities are coordinated, offering potential therapeutic targets for immune-related disorders and cancer.
