cathepsin X/O [Suberites domuncula]

Protein Classification

C1 family peptidase( domain architecture ID 10119592)

C1 family peptidase (also called papain family protein) may be an endopeptidase or an exopeptidase, and catalyzes the hydrolysis of peptide bonds in substrates using a catalytic dyad of Cys and His residues; similar to Homo sapiens cathepsin Z

Cathepsin X; the only papain-like lysosomal cysteine peptidase exhibiting carboxymonopeptidase activity. It can also act as a carboxydipeptidase, like cathepsin B, but has been shown to preferentially cleave substrates through a monopeptidyl carboxypeptidase pathway. The propeptide region of cathepsin X, the shortest among papain-like peptidases, is covalently attached to the active site cysteine in the inactive form of the enzyme. Little is known about the biological function of cathepsin X. Some studies point to a role in early tumorigenesis. A more recent study indicates that cathepsin X expression is restricted to immune cells suggesting a role in phagocytosis and the regulation of the immune response.

56-289 1.46e-54

Peptidase C1A subfamily (MEROPS database nomenclature); composed of cysteine peptidases (CPs) similar to papain, including the mammalian CPs (cathepsins B, C, F, H, L, K, O, S, V, X and W). Papain is an endopeptidase with specific substrate preferences, primarily for bulky hydrophobic or aromatic residues at the S2 subsite, a hydrophobic pocket in papain that accommodates the P2 sidechain of the substrate (the second residue away from the scissile bond). Most members of the papain subfamily are endopeptidases. Some exceptions to this rule can be explained by specific details of the catalytic domains like the occluding loop in cathepsin B which confers an additional carboxydipeptidyl activity and the mini-chain of cathepsin H resulting in an N-terminal exopeptidase activity. Papain-like CPs have different functions in various organisms. Plant CPs are used to mobilize storage proteins in seeds. Parasitic CPs act extracellularly to help invade tissues and cells, to hatch or to evade the host immune system. Mammalian CPs are primarily lysosomal enzymes with the exception of cathepsin W, which is retained in the endoplasmic reticulum. They are responsible for protein degradation in the lysosome. Papain-like CPs are synthesized as inactive proenzymes with N-terminal propeptide regions, which are removed upon activation. In addition to its inhibitory role, the propeptide is required for proper folding of the newly synthesized enzyme and its stabilization in denaturing pH conditions. Residues within the propeptide region also play a role in the transport of the proenzyme to lysosomes or acidified vesicles. Also included in this subfamily are proteins classified as non-peptidase homologs, which lack peptidase activity or have missing active site residues.

56-287 2.06e-47

Cathepsin C; also known as Dipeptidyl Peptidase I (DPPI), an atypical papain-like cysteine peptidase with chloride dependency and dipeptidyl aminopeptidase activity, resulting from its tetrameric structure which limits substrate access. Each subunit of the tetramer is composed of three peptides: the heavy and light chains, which together adopts the papain fold and forms the catalytic domain; and the residual propeptide region, which forms a beta barrel and points towards the substrate's N-terminus. The subunit composition is the result of the unique characteristic of procathepsin C maturation involving the cleavage of the catalytic domain and the non-autocatalytic excision of an activation peptide within its propeptide region. By removing N-terminal dipeptide extensions, cathepsin C activates granule serine peptidases (granzymes) involved in cell-mediated apoptosis, inflammation and tissue remodelling. Loss-of-function mutations in cathepsin C are associated with Papillon-Lefevre and Haim-Munk syndromes, rare diseases characterized by hyperkeratosis and early-onset periodontitis. Cathepsin C is widely expressed in many tissues with high levels in lung, kidney and placenta. It is also highly expressed in cytotoxic lymphocytes and mature myeloid cells.

56-288 3.62e-42

Cathepsin B group; composed of cathepsin B and similar proteins, including tubulointerstitial nephritis antigen (TIN-Ag). Cathepsin B is a lysosomal papain-like cysteine peptidase which is expressed in all tissues and functions primarily as an exopeptidase through its carboxydipeptidyl activity. Together with other cathepsins, it is involved in the degradation of proteins, proenzyme activation, Ag processing, metabolism and apoptosis. Cathepsin B has been implicated in a number of human diseases such as cancer, rheumatoid arthritis, osteoporosis and Alzheimer's disease. The unique carboxydipeptidyl activity of cathepsin B is attributed to the presence of an occluding loop in its active site which favors the binding of the C-termini of substrate proteins. Some members of this group do not possess the occluding loop. TIN-Ag is an extracellular matrix basement protein which was originally identified as a target Ag involved in anti-tubular basement membrane antibody-mediated interstitial nephritis. It plays a role in renal tubulogenesis and is defective in hereditary tubulointerstitial disorders. TIN-Ag is exclusively expressed in kidney tissues.

58-277 1.69e-28

C1 Peptidase family (MEROPS database nomenclature), also referred to as the papain family; composed of two subfamilies of cysteine peptidases (CPs), C1A (papain) and C1B (bleomycin hydrolase). Papain-like enzymes are mostly endopeptidases with some exceptions like cathepsins B, C, H and X, which are exopeptidases. Papain-like CPs have different functions in various organisms. Plant CPs are used to mobilize storage proteins in seeds while mammalian CPs are primarily lysosomal enzymes responsible for protein degradation in the lysosome. Papain-like CPs are synthesized as inactive proenzymes with N-terminal propeptide regions, which are removed upon activation. Bleomycin hydrolase (BH) is a CP that detoxifies bleomycin by hydrolysis of an amide group. It acts as a carboxypeptidase on its C-terminus to convert itself into an aminopeptidase and peptide ligase. BH is found in all tissues in mammals as well as in many other eukaryotes. It forms a hexameric ring barrel structure with the active sites imbedded in the central channel. Some members of the C1 family are proteins classified as non-peptidase homologs which lack peptidase activity or have missing active site residues.
