Thioredoxin pseudogene 4 (TXNP4)

Thioredoxin pseudogene 4 (TXNP4) is annotated as a *pseudogene*, meaning it is a non-functional copy or derivative of a thioredoxin gene. Unlike functional thioredoxins, which act as central antioxidant enzymes involved in redox regulation and cellular signaling[1][3][5][7], TXNP4 does not encode an active protein and lacks recognized enzymatic function. Most pseudogenes, including TXNP4, are best regarded as *noncoding genetic elements* that occasionally may act at the RNA level to regulate their parent genes by serving as miRNA decoys or through antisense interaction, though no functional studies directly implicate TXNP4 in such mechanisms. Thus, it is not considered a therapeutic target, receptor, enzyme, or signaling molecule by current biomedical standards[4][6]. Additional context: - True thioredoxin proteins (encoded by TXN, TXN2) have important antioxidant, redox signaling, and cell survival functions and are considered therapeutic targets in cancer and oxidative stress, but TXNP4 is *not* one of these[1][3][7]. - Pseudogenes may occasionally acquire regulatory or pathological relevance (e.g., via ceRNA/miRNA sponge effects), though TXNP4 has not been characterized in this way in the literature[4][6]. Summary: TXNP4 is a non-protein-coding pseudogene and not a canonical therapeutic target. If a therapeutic function or disease role is required, refer to the canonical functional gene, *Thioredoxin* (TXN)[1][3][7].
