일반 설명
Research area: Cell Signaling
Cathepsin L is a papain-like cysteine protease and belongs to the Clan A, Family C1. It is composed of L domain of α-helix and an R domain of β-sheet in the spatial structure.
Human cathepsin L (GenBank Accession No. NM_001912), amino acids 18-333, with C-terminal HIS tag, MW = 36 kDa, expressed in FreeStyle 293-F cells.

애플리케이션
Active human cathepsin L is useful for the activation of DPP1 (Cathepsin C). Active human cathepsin L has been used:
- to determine that N-acyl and N-sulfonyloxazolidine-2,4-diones are pseudo-irreversible inhibitors of serine proteases
- to investigate the role of cathepsin B and L activity in the serum during the human aging process.
- in inhibitory activity assay
- to study the role of CTSL in COVID-19 infection
생화학적/생리학적 작용
Cathepsin L is a cysteine protease, involved primarily in protein breakdown in the lysosome. Cathepsin L degrades nuclear transcription factors and may affect cell cycle regulation. Cathepsin L is also involved in the immune system, specifically in degrading the invariant chain during major histocompatibility complex (MHC) class II processing, a crucial step in antigen presentation. Its expression in the thymus has been demonstrated to be vital for the development of natural killer cells. Additionally, Cathepsin L contributes to recycling processes during axon outgrowth and synapse formation in the developing postnatal central nervous system. Proteases are associated with the development and progression of cancer. Therefore, cathepsin L may be a potential therapeutic target in cancer treatment.
