ZNF133 antisense RNA 1 (ZNF133-AS1)

ZNF133 antisense RNA 1 (ZNF133-AS1) is a long noncoding RNA transcript antisense to ZNF133, a gene encoding zinc finger protein 133. Antisense RNAs such as ZNF133-AS1 typically function by regulating the expression of their corresponding sense genes through various mechanisms, including transcriptional interference, chromatin modification, or RNA-RNA interactions. While antisense RNAs play fundamental roles in gene regulation, imprinting, and epigenetic control, no disease, drug, or clinical application is currently linked specifically to ZNF133-AS1. The locus and function are curated in gene databases, and no significant curatorial or spelling errors are present at this time. Antisense RNAs are increasingly studied for their impact in cancer and gene expression regulation; however, ZNF133-AS1 has no documented clinical, pharmacological, or pathological role apart from its molecular function as a noncoding regulatory RNA. ZNF133 itself (the protein-coding gene) has tumor suppressor relevance in breast cancer, but ZNF133-AS1 is distinct, with no therapy or disease implication documented.
