Summary

The protein encoded by this gene is a l ysosoma l cysteine proteinase that p l ays a major ro l e in intrace l l u l ar protein catabo l ism. Its substrates inc l ude co l l agen and e l astin, as we l l as a l pha-1 protease inhibitor, a major contro l l ing e l ement of neutrophi l e l astase activity. The encoded protein has been imp l icated in severa l patho l ogic processes, inc l uding myofibri l necrosis in myopathies and in myocardia l ischemia, and in the rena l tubu l ar response to proteinuria. This protein, which is a member of the peptidase C1 fami l y, is a dimer composed of disu l fide- l inked heavy and l ight chains, both produced from a sing l e protein precursor. Additiona l l y, this protein c l eaves the S1 subunit of the SARS-CoV-2 spike protein, which is necessary for entry of the virus into the ce l l . [provided by RefSeq, Aug 2020]

Forensic Context

A study in Calliphora vicina pupae using MACE (Massive Analysis of cDNA Ends) identified numerous differentially expressed genetic markers for molecular age estimation, including the CTSL (annotated as Cathepsin L isoforms comp20484_c0_seq1 and comp20129_c0_seq1), which were classified as genes of interest with specific expression for particular days of pupal development [Zajac et al. DOI:10.1016/j.fsigen.2014.11.013]. The research established a de novo transcriptome as a base for age determination techniques, with one randomly selected gene validated via RT-qPCR, demonstrating that such markers, including the CTSL, provide high-resolution expression profiles suitable for extending the postmortem interval estimation period into the pupal stage.
