ZCCHC13 (zinc finger CCHC-type containing 13) is a human protein encoded by the ZCCHC13 gene, belonging to the zinc finger protein family characterized by conserved CCHC motifs involved in nucleic acid binding. Structurally, it contains a tandem array of CCHC-type zinc finger domains, which typically mediate interactions with RNA or DNA. While its precise biological functions remain under investigation, emerging studies suggest its involvement in multiple cellular processes.
ZCCHC13 has been implicated in viral defense mechanisms, notably through its interaction with HIV-1 RNA to potentially restrict viral replication. It also associates with telomerase components (e.g., TERC RNA), hinting at a regulatory role in telomere maintenance and cellular senescence. Additionally, it may participate in innate immune signaling pathways, particularly in modulating interferon responses. Aberrant ZCCHC13 expression has been observed in certain cancers and age-related disorders, though its mechanistic contributions to disease pathogenesis require further validation.
Recombinant ZCCHC13 protein is commonly produced in bacterial or mammalian expression systems for functional studies. Its biochemical properties, such as RNA-binding specificity and interactions with viral or cellular partners, make it a subject of interest in antiviral research, aging biology, and oncology. Current challenges include elucidating its full interactome and resolving structural details of its zinc finger domains.
