ZNF346 is a zinc finger protein that functions as an RNA-binding protein with nucleic acid binding specificity. It binds with low affinity to double-stranded DNA and single-stranded RNA, but exhibits high affinity for double-stranded RNA with no detectable sequence specificity 1. ZNF346 may also bind to specific miRNA hairpins 2. The protein demonstrates preferential binding to DNA-RNA hybrids over other nucleic acid forms, making it useful for miRNA detection applications 3. In cancer contexts, ZNF346 appears to have oncogenic roles, being highly expressed and associated with poor prognosis in hepatocellular carcinoma 4. In neuroblastoma, ZNF346 is targeted by tumor suppressor miR-1247, and its downregulation inhibits cell proliferation and induces cell cycle arrest and apoptosis 5. ZNF346 has also been identified as a target for autoantibodies in colorectal cancer patients, suggesting potential diagnostic applications 6. Additionally, ZNF346 variants have been associated with premature menopause susceptibility 7 and uterine fibroid risk 8, indicating broader roles in reproductive health and disease.
