Background

  • Function

    Cathepsin L (CTSL) is a ubiquitously expressed lysosomal cysteine proteinase involved in lysosomal proteolysis, MHC class II antigen presentation, prohormone processing, and extracellular matrix remodeling[1]. Mechanistically, CTSL supports invariant chain degradation in cortical thymic epithelial cells and contributes to CD4+ T-cell selection in the thymus[2]. It also regulates positively selecting peptide ligands independently of invariant chain degradation, showing that CTSL affects thymic MHC class II presentation through more than one mechanism[3]. In skin models, CTSL deficiency causes periodic hair loss, epidermal hyperplasia, altered hair follicle morphogenesis, and disturbed hair follicle cycling[1]. Keratinocyte hyperproliferation in CTSL-knockout mice results from enhanced recycling of growth factors and receptors from endosomes to the plasma membrane[4]. Compared with related isoforms, human cathepsin V is highly homologous to cathepsin L, is expressed in human thymus and testis, and lacks a mouse orthologue[5]. In SARS-CoV-2 models, CTSL cleaves spike protein and enhances viral entry, while CTSL inhibition reduces pseudovirus infection in vitro and in vivo[6]. For experimental applications, small-molecule inhibitors and functional probes help define human CTSL mechanisms in specific cellular contexts[7].
