Cathepsin L pseudogene

Cathepsin L pseudogene (ENSG00000234460) is a genomic DNA sequence resembling the cathepsin L gene but is classified as a pseudogene, meaning it is transcriptionally inactive and does not encode a functional protein product. Cathepsin L itself is an important cysteine protease involved in lysosomal protein degradation, antigen presentation, and other cellular processes, and dysregulated cathepsin L activity has been implicated in diseases including cancer and viral entry. However, the pseudogene variant contains disabling mutations or lacks regulatory features essential for functional expression. There is no evidence that this pseudogene is a therapeutic target or has direct biological or clinical relevance. Additional Context: - Functional cathepsin L (CTSL) is a classical cysteine protease in the endopeptidase family, but the pseudogene does not function in this capacity. - Pseudogenes, such as "cathepsin L pseudogene," often arise from gene duplication or retrotransposition events and generally do not have functional protein products, though in rare cases some may regulate related genes via non-coding RNA roles—no such functions are established for ENSG00000234460. - Drug discovery efforts focus on the protein-coding "cathepsin L" (gene symbol CTSL or CTSL1 in humans), not on pseudogenes. If structured information is required for a true therapeutic target, refer to the functional protein "cathepsin L" or "cathepsin L1" (gene: CTSL, Ensembl: ENSG00000135047), not the pseudogene.
