Description: Stats (Signal transducers and activators of transcription) are a family of cytoplasmic latent transcription factors that are activated to regulate gene expression in response to a large number of extracellular signaling polypeptides including cytokines, interferons, and growth factors. After phosphorylation by JAK tyrosine kinases, Stats enter the nucleus to regulate transcription of many different genes.

Description: Protein Kinase C (PKC) is a large superfamily of serine/threonine kinases that mediate essential cellular signals required for activation, proliferation, differentiation and survival. There are at least ten PKC isotypes that are closely related in structure but that have distinct patterns of tissue distribution and function. The PKC isotypes can be subdivided into three classes based on primary structure and biochemical properties. These are: classical or conventional PKC isotypes (cPKC), novel PKC isotypes (nPKC) and atypical PKC isotypes (aPKC).

Description: Isotype matched controls are useful in flow cytometry to determine a gross estimate of non-specific binding that may be observed with a specific antibody of interest. In general, an isotype control should be of the same species and isotype as the antibody of interest, used at the same concentration, and conjugated to the same fluorophore. This reagent is an IgG1 isotype mouse monoclonal antibody (Clone # MOPC-21), conjugated to DyLight™-488. It is intended for use as an isotype control antibody for flow cytometry.

Description: HETEs are byproducts generated by the metabolism of arachidonic acid by lipoxygenases. 12(S)-HETE is the stereospecific hydroxy product from the reduction of 12(S)-hydroperoxy tetraenoic eicosatetraenoic acid [12(S)-HpETE], which itself is a 12-lipoxygenase metabolite of arachidonic acid. 12(S)-HETE is chemotactic and chemokinetic for polymorphonuclear leukocytes and vascular smooth muscle cells. It also acts as a second messenger in angiotensin-II induced aldosterone production. 15-hydroxyeicosatetraenoic acid [15(S)-HETE] is the major hydroxy derivative of arachidonic acid when acted upon by 15-lipoxygenase. It is also the primary monohydroxy acid synthesized by the lipoxygenase activity of Cyclooxygenase-1 upon linoleic acid. 15(S)-HETE acts as a paracrine regulator of smooth muscle and lung neutrophil recruitment, and elevated levels of 15(S)-HETE are associated with asthma, rhinitis, chronic paranasal sinusitis and rheumatoid arthritis.

Description: 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).

Description: FKBP59, also known as Hsp56/p59 is an immunophilin that is a component of Hsp70/Hsp90/steroid receptor complexes. Expression of FKBP59 is increased in response to heat shock and ischemic stress, and is thought to play a role in the folding and cytoplasmic/nuclear distribution of steroid receptors.

Description: Calnexin (CNX), an unglycosylated resident ER transmembrane protein, together with Calreticulin (CRT), plays a key role in glycoprotein folding and its control within the ER, by interacting with folding intermediates via their monoglucosylated glycans. Calnexin associates with newly synthesized monomeric glycoproteins and only recognizes glycoproteins when they are incompletely folded. Furthermore, Calnexin has been demonstrated to function as a molecular chaperone capable of interacting with polypeptide segments of folding glycoproteins.

Description: Endoplasmic reticulum protein (ERp) 72, a 72 kDa protein localized to the endoplasmic reticulum, is a member of the Protein Disulfide Isomerase (PDI) family of proteins. Together with other ER resident proteins such as BiP, GRP94, and PDI, they serve as the molecular chaperones for proper folding of newly translocated and glycolsylated proteins such as Thyroglobulin (Tg) and Human chorionic gonadotropin (hCG)-beta.

Description: The GST superfamily of enzymes play an important role in detoxification of xenobiotics by catalyzing the conjugation of many hydrophobic and electrophilic compounds with reduced glutathione. There are four main GST classes; alpha, mu, pi, and tau. GST-P is a member of the pi class of GSTs, and its expression is specifically increased in the early stages of rat hepatocarcinogenesis. Due to its high affinity for glutathione, GST is frequently utilized as an approximately 26 kDa fusion tag for the expression and purification of recombinant proteins.

Description: Agrin is an essential extracellular matrix component which promotes clustering of nicotinic acetylcholine receptors (nAChRs) and other proteins at the neuromuscular junction during development. Agrin, MuSK, and Rapsyn are all essential components for AChR aggregation, through an unknown mechanism. The C-terminal region of agrin is released into the medium, interacts with receptors on the muscle surface and induces AChR aggregation.

Description: Cytochrome c is an electron transport protein from mitochondria.  A primary means of caspase activation by p53 is through induction of cytochrome c release from mitochondria.  Cleavage of Bid, a Bcl 2 family member, by caspase-8 produces a truncated tBid molecule which triggers mitochondria release of cytochrome c which binds to the adaptor protein Apaf-1 and procaspase-9 to form a cytosolic apoptosome complex.  This event results in activation of procaspase-9 and its subsequent cleavage and activation of caspase-3 leading to the degradation of a series of cellular substrates and subsequently cell death.

Description: Hsp27 is one of the most common members of the highly conserved and ubiquitously expressed family of small heat shock proteins (sHsp), which also includes alphaB-crystallin. It is characterized by a conserved C-terminal alpha-crystallin domain consisting of two anti-parallel beta-sheets that promote oligomer formation required for its primary chaperone function as inhibitor of irreversible protein aggregation. Hsp27 oligomerization is modulated by post-translational phosphorylation of Hsp27 at three serine residues, Ser15, Ser78, and Ser82, by a variety of protein kinases including MAPKAPK-3, PKAc-alpha, p70 S6K, PKD I, and PKC-delta. Hsp27 has been shown to inhibit actin polymerization by binding of unphosphorylated Hsp27 monomers to actin intermediate filaments. Anti-apoptotic functions of Hsp27 have also been identified through interactions with DAXX7, activation of Akt, and inhibition of apoptosome formation. Evidence suggests altered expression of Hsp27 is implicated in the pathogenesis of breast, ovarian, and prostate cancer.

Description: 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.

Description: Hsp 110 belongs to a family of large stress proteins known as the Hsp110/SSE family, the mostly overlooked relatives of the well studied Hsp70 family. Members of this group, while significantly larger and containing sequences not present in the Hsp70 family, share 30-33% amino acid identity with members of the Hsp70 family, mostly in the conserved ATP-binding domain. Presently, all identified members of the Hsp70-like sequences belong to either the Hsp70 family or the Hsp110/SSE family. Hsp110 appears to be a normal constituent of mammalian cells with highest expression in the brain, and its induction by heat shock strongly correlates with cellular thermotolerance. Hsp110 may contribute to RNA stability, and its capacity to bind peptide has made Hsp110 a promising immunoadjuvant in anti-tumor vaccine development.
