ZC3H7A is a CCCH-type zinc finger protein implicated in RNA regulation and tumorigenesis. As a putative miRNA biogenesis regulator, ZC3H7A binds specific microRNA hairpins (MIR7-1, MIR16-2, MIR29A) through recognition of 3'-ATA(A/T)-5' motifs in apical loops, suggesting roles in post-transcriptional gene expression control. At the tissue level, ZC3H7A is enriched in macrophage-related organs (thymus, spleen, lung, intestine, adipose tissue) and shows coordinated expression changes during macrophage activation, positioning it within a functional module regulating immune cell responses 1. Clinically, ZC3H7A is notably associated with aggressive malignancies. It forms fusion proteins with BCOR in soft tissue sarcomas, particularly high-grade endometrial stromal sarcomas and malignant ossifying fibromyxoid tumors, characterized by poor prognosis with three of four patients dying of disease 2. Additionally, ZC3H7A::RET fusion represents a rare but recurring translocation in non-small-cell lung carcinoma 3. In pancreatic ductal adenocarcinoma, ZC3H7A mutations cluster with metastasis-driving genes (KRAS, TP53) in cancer networks and show functional impacts on cancer cell migration and proliferation 4, suggesting ZC3H7A dysfunction contributes to metastatic progression.
