H2A.Z histone pseudogene 1 (H2AZP1)

H2A.Z histone pseudogene 1 (H2AZP1) is classified as a **pseudogene** and not a protein-coding gene, nor is it a canonical therapeutic target such as a receptor, enzyme, transporter, or transcription factor. While the H2A.Z family (including H2A.Z.1 and H2A.Z.2) comprises canonical histone variants playing key roles in chromatin structure and gene regulation[1][2][3][4][5][6], "H2A.Z histone pseudogene 1" specifically refers to a genomic locus that is **noncoding and does not generate functional protein**. Therefore, H2AZP1 should not be considered a therapeutic target, and there are no known biological functions, disease roles, interacting drugs, mechanisms of drug action, biomarkers, or safety concerns associated with it. The confusion often arises due to the similarity in name with the functional H2A.Z variants, but H2AZP1 itself is not a functional histone or protein, and is not known to have any coding or regulatory biological activity. **Note:** H2A.Z functional variants (such as H2A.Z.1 and H2A.Z.2, encoded by the H2AFZ and H2AFV genes, respectively) are core histone proteins with important roles in gene expression, chromatin organization, and DNA repair[1][2][3][4][5][6]. However, H2AZP1 is explicitly annotated in genomic databases as a pseudogene and thus does not possess the functional properties associated with other H2A.Z proteins.
