C1QTNF9B antisense RNA 1 (C1QTNF9B-AS1)

C1QTNF9B antisense RNA 1 (C1QTNF9B-AS1), also referred to as PCOTH or Prostate collagen triple helix protein, is a **long non-coding RNA (lncRNA)**. Multiple sources confirm its classification as an RNA gene, not a receptor, enzyme, or classic druggable protein target. It is expressed in various tissues, including the prostate and testis, and is predicted to have functions related to the extracellular matrix or as a structural RNA. Some studies suggest a link to prostate cancer cell growth and potential regulatory roles, but **there is little direct evidence that C1QTNF9B-AS1 functions as a therapeutic target, receptor, or enzyme**. It is not currently associated with known pharmacological modulators or established clinical biomarkers. Existing references conflate protein-coding genes (such as C1QTNF9B) and the lncRNA (C1QTNF9B-AS1), but the target described in your query matches the lncRNA, not a classic protein target[2][4][5][6][7]. Therefore, there is a conceptual error in treating "PCOTH" or "C1QTNF9B-AS1" as a classic target; it should be cataloged as a long non-coding RNA, not a protein or receptor.
