Description:
Alpha-crystallins composed of alpha A (~20 kDa) and alpha B (~20 kDa) subunits, are major water-soluble proteins accounting for almost 50% of total protein in the mammalian transparent eye lens and they are also found in a variety of other tissues. The two other crystallin families, beta and gamma, are homologous to each other but not to the alpha family or the sHsp's. Alpha-crystallins are also referred to as small heat shock proteins, since they are induced by increased temperature in a variety of organisms. The alpha-crystallins have sequence homology as well as structural and functional similarities with the small Hsp's such as Hsp25/27. Most small heat shock proteins have four common structural and functional features: (i) molecular weight between 12 and 43kDa; (ii) the formation of large oligomeric complexes composed of alphaA-crystallin, alphaB-crystallin and Hsp25/27; (iii) the moderately conserved alpha-crystallin domain in the central region of the protein; and (iv) molecular chaperone activity. The alpha-crystallin domain comprises approximately 90 residues, is bounded by variable N-terminal and C-terminal extensions and is involved in oligomer assembly. Oligomers can reach 800kDa or more and are dynamic, exhibiting subunit exchanges and organizational plasticity, possibly leading to functional diversity. Phosphorylation of serine residues occurs during development and in response to stress, and usually decreases oligomer size. Chaperone activity requires, and is modulated by, oligomerization and is limited to binding unfolded intermediates to prevent irreversible aggregation, although productive release and refolding of denatured proteins requires close cooperation with other chaperones. Other proposed functions include a role in membrane stabilization and modulation of intermediate filament organization during physiological stress and neurodegenerative disease.

Description:
GrpE (Glucose Regulated Protein E. coli) is encoded by a monocistronic E. coli gene, which is under the control of both s32 and s70 transcription factors. The GrpE protein is a so-called co-chaperone because it is known to assist the DnaK (Hsp70) protein to effectively carry out DnaK-dependent chaperone activity (i.e. protein folding, protein transport, disaggregation of heat inactivated proteins, activation of mutant protein).

Description:
Glutathione, a major intracellular non-protein thiol, protects against free radical damage by providing reducing equivalents for several key antioxidant enzymes. In addition, glutathione acts as a scavenger of hydroxyl radicals and nascent oxygen. Elevated glutathione levels are associated with a reduced rate of illness, higher levels of self-rated health, lower cholesterol, lower body mass index, and lower blood pressure among the elderly. Glutathione provides a primary defense system for the removal of oxidants in the brain. Studies have revealed a correlation between low glutathione levels and damage to neurons that manufacture dopamine, suggesting a link to Parkinson's disease.

Description:
Cytochalasin D is a cell-permeable fungal toxin which binds to the barbed end of actin filaments inhibiting both the association and dissociation of subunits. It causes the disruption of actin filaments and inhibition of actin polymerization. It is about 10-fold more effective than cytochalasin B and does not inhibit monosaccharide transport across cell membranes. Inactivates low conductance K+ channels. Modulates CD4 cross-linking in T-lymphocytes and increases intracellular Ca2+ levels. Exhibits antitumor activity. Induces apoptosis.

Description:
All members of the inhibitor of apoptosis proteins (IAP) family contain at least one, but usually three copies of baculovirus IAP repeat (BIR), a ~70-aa zinc binding domain, and upon overexpression suppress apoptosis. The BIR motif is capable of interacting with caspases and occluding their catalytic pockets. Certain IAPs also possess C-terminal RING domains. RING-containing proteins often act as E3 ubiquitin ligases and can catalyse the degradation of both, themselves and selected target proteins through ubiquitylation. So far, eight human IAPs have been identified: Apollon (Bruce), c-IAP1 (HIAP2; MIHB), c-IAP2 (HIAP1; MIHC), ILP-2 (Ts-IAP), Livin (ML-IAP; KIAP), NAIP, Survivin (TIAP) and XIAP (ILP-1; MIHA). c-IAP1 has been shown to inhibit specific caspases.

Description:
The ryanodine receptor (RyR) is the channel responsible for the release of calcium from the sarcoplasmic reticulum (SR) in muscle cells and also plays a role in calcium regulation in non-muscle cells. The RyR exists as a homotetramer and is predicted to have a short cytoplasmic C-terminus and 4-10 transmembrane domains; the remainder of the protein, termed the "foot" region is located in the cytoplasm between the T-tubule and the SR. The mammalian RyR is the product of three different genes: RyR-1, which is expressed predominantly in skeletal muscle and areas of the brain, RyR-2, which is expressed predominantly in the heart muscle but also found in the stomach, endothelial cells and diffuse areas of the brain, and RyR-3 which is found in smooth muscle and the brain (striatum, thalamus and hippocampus).
