Fatty acid binding protein 5 pseudogene 9 (FABP5P9)

Fatty acid binding protein 5 pseudogene 9 (FABP5P9) is a human pseudogene related to the gene fatty acid binding protein 5 (FABP5). Unlike functional genes that encode active proteins, pseudogenes are generally regarded as non-functional copies or remnants of genes that have lost their protein-coding capability due to mutations. FABP5P9 does not encode a protein and does not have a documented role as a therapeutic target, biological function, or disease association. It should be distinguished from FABP5, which is a well-studied fatty acid-binding protein involved in lipid metabolism, signaling, and several diseases, but FABP5P9 itself is not a valid drug target nor a receptor, enzyme, or therapeutic marker[1]. Important note: FABP5P9 is sometimes confused with or referenced alongside FABP5 due to the shared gene family, but the pseudogene (FABP5P9) has no known functional role or therapeutic relevance. For literature and target information related to drug discovery or disease roles, consult entries for fatty acid binding protein 5 (FABP5), not its pseudogenes[2][3][4]. Summary of issues: - FABP5P9 is a pseudogene, not a functional protein or drug target. - No biological functions, disease associations, drugs, or mechanisms of action are documented for FABP5P9. - It may occasionally be listed in genomic or gene databases for completeness, but it does not encode a targetable product[1].
