Research area: Cell Signaling
Human cathepsin S (GenBank Accession No. NM_004079.3), CD33 signal peptide (amino acids 1-16) + cathepsin S (amino acids 17-331), with C-terminal HIS tag, MW = 37 kDa, expressed in FreeStyle 293-F cells. Cathepsin S belongs to the cysteine cathepsin protease family. It has limited tissue expression, being associated with antigen-presenting cells localized in lymph and spleen, as well as other immune cells like macrophages. Human cathepsin S is produced from its corresponding CTSS gene on chromosome 1q21 and is synthesized as a pre-proenzyme.[1]

アプリケーション
Active human cathepsin S has been used:
- to assess the pathogenesis of Alzheimer′s disease. [2]
- to investigate the optimization of selectivity of Azepanone-based inhibitors. [3]
- for the immunocytochemical detection of cathepsin-S in mouse samples.[4]
- for incubating mouse brain sections to test the impact of cathepsin-S on perineuronal nets (PNNs) integrity.[4]
生物化学的／生理学的作用
Cathepsin S, as a lysosomal protease, facilitates the breakdown of unwanted and damaged proteins in the endo-lysosomal pathway. Moreover, it plays specific roles, such as contributing to major histocompatibility complex (MHC) class II antigen presentation by aiding in the degradation of the invariant chain. Dysregulation of cathepsin S has been associated with various pathological conditions, such as cancer, arthritis, and cardiovascular disease.[1] Cathepsin S is useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. It is also used as a biomarker for atherosclerosis, diabetes, adiposity, and atherogenesis. Moreover, it acts as a promising target against brain-penetrating and for the treatment of multiple sclerosis and neuropathic pain.

We have expressed active human cathepsin S to 60 mg/L in Sf9 cells using a baculovirus system. Production of milligram quantities has facilitated crystallographic studies to determine the structure of this enzyme, which has unique properties among lysosomal cysteine proteinases.

Perineuronal nets (PNNs) are extracellular matrix (ECM) structures that envelop neurons and regulate synaptic functions. Long thought to be stable structures, PNNs have been recently shown to respond dynamically during learning, potentially regulating the formation of new synapses. We postulated

A series of azepanone inhibitors of cathepsin S is described. Selectivity over both cathepsin K and cathepsin L was achieved by varying the P2 substituent. Ultimately, a balanced potency and selectivity profile was achieved in compound 39 possessing a 1-methylcyclohexyl

Cathepsin S is a member of the cysteine cathepsin protease family. It is a lysosomal protease which can promote degradation of damaged or unwanted proteins in the endo-lysosomal pathway. Additionally, it has more specific roles such as MHC class II

β-site APP-cleaving enzyme (BACE1) cleaves the wild type (WT) β-site very slowly (k(cat)/K(m): 46.6 m(-1) s(-1)). Therefore we searched for additional β-secretases and identified three cathepsins that split the WT β-site much faster. Human cathepsin S cleaves the WT β-site
