Descrizione: α-Crystallins composed of αA (~19 kDa) and αB (~19.2 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. Alpha-crystallins are also referred to as small heat shock proteins, since they are induced by increased temperature in a variety of organisms. The α-crystallins have sequence homology as well as structural and functional similarities with the small Hsp’s such as Hsp25/27. Most α-crystallins have four common structural and functional features: (i) molecular weight between 12 and 43kDa; (ii) the formation of large oligomeric complexes composed of αA-crystallin, αB-crystallin and Hsp25/27; (iii) the moderately conserved α-crystallin domain in the central region of the protein; and (iv) molecular chaperone activity. The α-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 800 kDa 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. Alpha B Crystallin is phosphorylated on serine 45 by ERK1/2 and serine 59 by MAPKAPK-2. When mono-phosphoylated αB-crystallin is isolated it contains only αB-crystallin phosphorylated at serine 19.

Descrizione: Alpha-crystallins, which are part of the small Heat shock family members, are major water-soluble proteins present in the lens of the mammalian eye. Phosphorylation of serine residues which occurs during development and in response to stress, is intimately linked with its function. Chaperone activity requires, and is modulated by, oligomerization and is limited to binding unfolded intermediates to prevent irreversible aggregation.

Descrizione: Arginine vasopressin (AVP) is a nonapeptide hormone produced in magnocellular neurons of the hypothalamus, which functions as an antidiuretic in the kidney and systemically as a regulator of vasoconstriction, blood volume, and blood pressure. AVP acts by binding to a set of specific seven-transmembrane domain-containing G-protein coupled receptors (GPCR) classified into three groups: V1a (V1) receptors regulate vasoconstriction, and are expressed in vascular smooth muscle, kidney, myometrium, bladder, adipocytes, hepatocytes, platelets and testis; V1b (V3) receptors stimulate adrenocorticotropic hormone (ACTH) release in the anterior pituitary, but may also participate in corticotropin-releasing hormone (CRH) release by the hypothalamus; and V2 receptors of the kidney regulate the antidiuretic effects of AVP. The V1b receptor signals through coupling of Gq/11 alpha subunits, activating phospholipase C and release of intracellular Ca2+ via phosphoinositide second messengers. V1b receptor overexpression is a common marker for ACTH-secreting corticotropic adenomas.

Descrizione: Arachidonic acid is converted by cyclooxygenase (COX) to prostaglandin H2 (PGH2), which is further converted to the derivative prostanoids PGD2, PGE2, PGF2α, PGI2 (prostacyclin) and thromboxane A2 (TXA2). Five classes of prostanoid receptors are recognized and named DP, EP, FP, IP and TP receptors corresponding to the agonist properties of the associated prostanoids. FP receptors are found in smooth muscle where they mediate contraction, and are believed to be coupled via Gq/11 subunits to stimulate phosphatidyl inositol (PI) hydrolysis. The FP agonist Fluprostenol (a PGF2α analogue) is used in animal husbandry to synchronize oestrus and induce partruition. FP receptors are known to mediate intraocular pressure, and FP agonists such as latanoprost and travoprost are drugs commonly use to treat glaucoma.

Descrizione: Metabolism of inositol phospholipids by intracellular signaling mediators is fundamental to signal transduction in eukaryotic cells. PI-4,5-P2 (Phosphatidylinositol 4,5-bisphosphate; PIP2) can be synthesized by phosphorylation of PI-4-P by type I phosphatidylinositol phosphate kinase (PIP5K I), or phosphorylation of PI-5-P by type II PIPK (PIP4K II). PI-4,5-P2 regulation of cellular calcium levels involves its hydrolysis by Phospholipase C (PLC) to produce inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG), which serve as second messengers in the import of calcium via IP3-sensitive ion channels and in the activation of PKC, respectively.

Descrizione: 15-deoxy-Δ12,14-Prostaglandin J2 (15-d-PGJ2) is one of the ultimate dehydration products of PGD2, formed via the intermediate Δ12-PGJ2. 15-d-PGJ2 is physiologically present in body fluids at concentration of 10-12 to 10-9 M, but increases dramatically under stress such as infection and inflammation. 15-d-PGJ2 exerts both pro- and anti-inflammatory effects in a cell-type and concentration-dependent manner, with many of these effects mediated via binding to the γ isoform of the peroxisome proliferators-activated receptor (PPAR-γ). 15-d-PGJ2 appears to induce HO-1 expression by a PPAR-γ-independent mechanism mediated by the generation of reactive oxygen species (ROS).

Descrizione: FLAG-tag stands for an octapeptide with a sequence of DYKDDDDK. It is a polypeptide protein tag that can be added to a protein using recombinant DNA technology. It is widely used for affinity chromatography to purify recombinant proteins from variety of systems. It can also be used in the isolation of protein complexes with multiple subunits. A FLAG-tag can be used in many different assays that require recognition by an antibody. If there is no antibody against the studied protein, adding a FLAG-tag to this protein allows one to follow the protein with an antibody against the FLAG sequence, such as in ELISA, Western Blot, etc.

Descrizione: P62, also known as Sequestosome I, is a 62kDa, 440 amino acid protein, initially identified as a ligand of the SH2 domain of p56lck, now known to be expressed in many tissues. In addition to TRAF6, PEST and zinc finger motifs, p62 has a C-terminal ubiquitin binding association (UBA) domain with an affinity for multi-ubiquitin chains, and it is considered to serve as a scaffold protein, capable of binding to multiple signalling molecules and uniting receptor-mediated signalling events with ubiquitinylation. Elevated levels of p62 have been reported in breast tumours and in alcoholic liver disease where p62 has been shown to be involved in the formation of Mallory bodies. Several mutations in the p62 UBA domain have been identified and the etiology of Paget’s disease of bone has been linked to one such mutation. Kuusisto and colleagues have demonstrated that p62 is also present in elevated levels in the hallmark inclusions found in various neurodegenerative conditions, including tauopathies (Alzheimer’s disease, Picks disease, and frontotemporal dementia) and synucleinopathies (Parkinson’s disease, dementia with Lewy body disease and multiple system atrophy). In recent years ubiquitin immunostaining has been used to provide adjunct information for neuropathological diagnosis, but it is becoming evident that p62 may be an even more reliable marker of neurodegenerative disease inclusion detection than tau, alpha-synuclein or ubiquitin immunostaining.

Descrizione: Aurora A, B, and C have emerged as key mitotic regulators of mammalian centrosome function, chromosome segregation and cytokinesis. Aurora B is one of several chromosomal passenger proteins involved in chromosome alignment at the metaphase plate and cytokinesis. Phosphorylation of a threonine residue in the Aurora activation loop (Thr232 in human Aurora B) is believed to be an essential regulatory mechanism in Aurora kinase activation.
