caspase: (kas'pās), An enzyme implicated in apoptosis, which c leaves proteins after asp aratic acid. (Thus, c asp ase.). caspases: (kas'pās-ĕz), Proteolytic cleavage products of the protein's procaspases that are responsible for cleaving and activation of additional procaspases into more caspases, thus resulting in a cascade of proteolytic activity the final result of which is apoptosis of the cell. [ c ysteinyl a spartate s pecific proteinase].
Apoptosis, derived from the Greek word for the natural process of leaves falling from trees, is a distinct form of programmed cell death (Kerr et al., ; Kerr, ).Although such programmed deaths were described many decades ago, the significance of apoptosis was largely overlooked, in particular, its relevance to disease.

Caspases work as heterotetramers, that is, an assembly of four domains (Fig. ).Most mammalian caspases have two p20 domains and two p10 domains. The p20 domain has the enzyme active site; therefore, each active caspase can. Caspase-3 is a caspase protein that interacts with caspase-8 and caspaseIt is encoded by the CASP3 3 orthologs have been identified in numerous mammals for which complete genome data are available.
Unique orthologs are also present in Aliases: CASP3, CPP32, CPP32B, SCA-1, caspase 3. Caspase is the family of cysteine proteases that are Ced-3 homologues. Caspases book mammals, more than 10 caspases have been identified. Caspases are made as inactive proform. After being cleaved, they become active.
Among the caspases, caspase-3 has the highest homology to Ced The functions of caspase-2,and are less easily categorized. Caspases involved in apoptosis have been subclassified by their mechanism of action and are either initiator caspases (caspase-8 and -9) or executioner caspases (caspase-3, -6, and -7).

The intracellular machinery responsible for apoptosis seems to be similar in all animal cells. This machinery depends on a family of proteases that have a cysteine at their active site and cleave their target proteins at specific aspartic acids.
They are therefore called es are synthesized in the cell as inactive precursors, or procaspases, which are usually activated by Cited by: Caspase-9 is an enzyme that in humans is encoded by the CASP9 is an initiator caspase, critical to the apoptotic pathway found in many tissues.
Caspase-9 homologs have been identified in all mammals for which they are known to exist, such as Mus musculus and Pan troglodytes.
Caspase-9 belongs to a family of caspases, cysteine-aspartic proteases involved in apoptosis Aliases: CASP9, APAF-3, APAF3, ICE. Cell-Cycle Cross Talk with Caspases and Their Substrates Connolly, -Carpio, ger, A.
The Killer Pseudokinase Mixed Lineage Kinase Domain-Like Protein (MLKL). Inactive caspases contain a pro-domain, a large subunit and a small subunit. According to their pro-domain structure and function, caspases are divided into “inflammatory”, “initiator” and “effecter” caspases (Figure 2A) (Nicholson, ; Hengartner, ).
Caspases are normally present as inactive precursors in by: 1. Caspase-9 is an initiator caspase--one that begins the process of apoptosis. It receives the message to begin work, becomes activated, and then makes a cut in the effector caspases, such as caspase-3 shown at the bottom (PDB entry 1pau).
Caspase-3, along with other effector caspases, then begin the heavy work of disassembling the cell. The Caspase cascade is activated by two distinct routes: one from cell surface and the other from mitochondria (Ref.1).
The pathway leading to Caspase activation varies according to the apoptotic stimulus. Initiator Caspases (including 8, 9, 10 and 12) are closely coupled to pro-apototic signals.
Caspases-3, -6 and The shared structural characteristic of caspases-3, -6 and -7 is a short prodomain connected with a CASc. This property suggests that they are unable to form a complex with other molecules through their by: Caspases are a family of aspartate-specific, cysteine proteases that serve as the primary mediators of apoptosis.
Mammalian caspases can be subdivided into three functional groups, apoptotic initiator caspases (Caspase-2, -8, -9, ), apoptotic effector caspases (Caspase-3, -6, -7), and caspases involved in inflammatory cytokine processing.

Published on This 3D medical animation explains the functioning of the extrinsic and intrinsic apoptotic pathways. We start off by taking a look at the important role apoptosis plays. Read our article on Apoptosis Caspase Pathways. A group of intracellular proteases called caspases are responsible for the deliberate disassembly of the cell into apoptotic bodies during apoptosis.
1 Caspases are present as inactive pro-enzymes that are activated by proteolytic cleavage. Caspases 8, 9 and 3 are situated at pivotal junctions in apoptosis pathways. Apoptosis is a natural guard against disorders and diseases which is performed throughout programmed cell death.
The process of apoptosis involves a diversity of enzymatic mechanisms. described in this book chapter, apoptotic caspases are of primary focus due to the extensive structural database on the subclass of caspases (Enari et al., ). Caspases can activate one another: the prodomain is cleaved from the procaspase, and the small and large subunits of the two caspases form an active caspase – heterotetramer (Figure 2), which contains two active centres.
Caspases of the initiator (pro-apoptotic and pro-inflammatory) type contain a long prodomain made up of approximately Author: Tatyana O.
Volkova, Alexander N. Poltorak. Caspases, Paracaspases, and Metacaspacses: Methods and Protocols is a collection of laboratory protocols covering current methods that are employed to measure and detect activities of these proteases in diverse biological systems, ranging from unicellular organisms to mammals.
Broken into two parts, the first part focuses on methods to measure, detect, and inhibit. The volume offers insight into the key research topics that involve caspases. Leading experts from various areas of biology and medicine have compiled this volume so that both the novice and the professional will use this as the main reference for caspases for years to .caspase Any of various enzymes that cleave target proteins during programmed cell death (see apoptosis).
Caspases are formed from inactive precursors present in the cell in response to certain triggers, such as cell damage (e.g. bursting of mitochondria). They then initiate a cascade of cleavage events, possibly by liberating other ‘executioner’ enzymes, which chop up the.
