Description: IDO catalyzes the first and rate-limiting step in the main pathway of human tryptophan catabolism, the kynurenine pathway. Proinflammatory mediators, such as endotoxin and IFN-gamma induce the expression of IDO in several tissues. IDO-dependent suppression of T-cell responses might function as natural immunoregulatory mechanism. Physiological IDO activity has been implicated in T-cell tolerance to tumors, dysfunctional selftolerance in non-obese diabetic (NOD) mice, and as a protective negative regulator in autoimmune disorders.

Description: This peptide is Exendin-4 labeled with fluorescein at the Tryptophan residue. FLEX is equipotent to GLP-1(7-36)-amide and exendin-4 as an inhibitor of [125I] GLP-1 binding to the human GLP-1 receptor stably expressed in CHO cells, and maintains full biological potency and efficacy as measured by the stimulation of cAMP accumulation in these cells. FLEX binding to CHO/hGLP-1R membranes results in an increase in fluorescence anisotropy. The binding is specific and saturable (Kd = 2.0 +/- 0.4 nM), and GLP-1(7-36)-amide and Exendin-4 are equipotent inhibitors of FLEX binding to the human GLP-1 receptor. Thus, FLEX is a potent, biologically active ligand that is useful for the study of the binding and functional characteristics of the human GLP-1 receptor.

Description: This gene encodes a member of the pterin-dependent aromatic acid hydroxylase family. The encoded protein catalyzes the first and rate limiting step in the biosynthesis of serotonin, an important hormone and neurotransmitter. The human genome contains two related tryptophan hydroxylases, one on chromosome 11p15 to p14 and one on chromosome 12q21. This gene is expressed predominantly in the brain stem. Mutations in this gene may be associated with psychiatric diseases such as bipolar affective disorder and major depression.

Description: This gene encodes a protein that associates with the enzyme phosphoribosylpyrophosphate synthetase (PRS). PRS catalyzes the formation of phosphoribosylpyrophosphate which is a substrate for synthesis of purine and pyrimidine nucleotides, histidine, tryptophan and NAD. PRS exists as a complex with two catalytic subunits and two associated subunits. This gene encodes a non-catalytic associated subunit of PRS. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011].

Description: Fluorogenic substrate for several matrix metalloproteinases (MMPs). It is cleaved by MMP-1 (kcat/Km=3.3x10M-1s-1), MMP-2 (kcat/Km=5.8x10), MMP-3 (kcat/Km=2.2x10), MMP-7 (kcat/Km=1.2x10), MMP-8, MMP-9 (kcat/Km=6.9x10), and MMP-26 (kcat/Km=4.9x10) Ex/Em=280nm/346nm, although 283/350,360 are also appropriate. Fluorescence at 346 nm by tryptophan occurs once cleavage separates it from the quenching aromatic Dnp moiety. MMPs cleave this peptide between Gly-Leu.

Description: 7-Azido-4-methylcoumarin is a highly sensitive and selective fluorogenic H2S probe. The aromatic azide moiety of AzMC is selectively reduced in the presence of H2S, producing the fluorescent 7-amino-4-methylcoumarin (AMC) with a concomitant increase in fluorescence with lambdaex = 365 nm and lambdaem = 450 nm. It is a photoaffinity labeling probe for the substrate binding site of human sulfotransferase 1A1 (SULT1A1). 7-Azido-4-methylcoumarin is a tool for monitoring the activity of pyridoxal-5'-phosphate (PLP)-dependent enzymes (e.g. cystathionine beta-synthase (CBS), cystathionine gamma-lyase (CGL) and tryptophan synthase (TS)) and to identify novel cystathionine beta-synthase (CBS) inhibitors and activators.

Description: Indoleamine 2,3-dioxygenase (IDO) is a heme enzyme that initiates the oxidative degradation of the least abundant, essential amino acid, l-tryptophan, along the kynurenine pathway. This protein is normally expressed in the dendritic cells, macrophages, microglia, eosinophils, fibroblasts, endothelial cells, and most tumor cells. IDO activity is associated with immunosuppression and immune attenuation. Several studies showed that IDO can contribute to immune escape when expressed directly in tumor cells or when expressed in immunosuppressive antigen presenting cells such as tolerogenic dendritic cells or tumor associated macrophages. IDO also is a promising therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression.

Description: 14-3-3 proteins are highly conserved proteins which play a role in both signal transduction and progression through the cell cycle by binding to and regulating several different proteins. 14-3-3 proteins activate tyrosine and tryptophan hydroxylases and protein kinase C. They mediate signal transduction by binding to phosphoserine-containing proteins. There are at least 7 mammalian isoforms: alpha, beta, gamma, delta, epsilon, zeta, and eta. An eighth subtype, termed theta has been found in rat brain. The 14-3-3 proteins exists in vitro and in vivo as either homo- or heterodimers which interact via their N-terminal domains and are subject to phosphorylation by protein kinase C. 14-3-3 proteins are localized in the cytoplasma of neurons in the cerebral cortex and are axonally transported to the nerve terminals. They may be present at lower levels in various other eukaryotic tissues. Northern blot analysis has shown expression of the eta chain in cultured cell lines derived from various tumors.
