Phosphotyrosine is a tyrosine residue covalently bound to a phosphate via its hydroxyl group. A tyrosine kinase catalyzes the transfer of a phosphate from ATP to a tyrosine residue on the protein substrate. Tyrosine phosphorylation plays a key role in intracellular signaling and cancer development....

Opioid receptors and their endogenous peptide ligands play important roles in the reward and reinforcement of drugs such as heroin, cocaine, and alcohol. The ?-opioid receptor is a type of opioid receptor which binds the peptide opioid dynorphin as the primary endogenous ligand. ?-opioid receptors...

Alpha-MSH (alpha melanocyte-stimulating hormone) is an ancient tridecapeptide with potent inhibitory activity in all major forms of inflammation. ACTH has structural similarities to alpha-MSH. ACTH and alpha-MSH can induce grooming, stretching, yawning, penile erection responses in male rats, site...

Beta-amyloid peptide (beta-APP) is a 40-residue peptide implicated in the pathogenesis of Alzheimer’s disease (AD) and aged Down's Syndrome, which is promoted by the acquisition of an additional copy of chromosome 21. The peptide is a proteolytic product of the much larger amyloid...

Well-characterized antibodies for epitope tags consisting of short sequences have been widely used in the study of protein expression in various systems. The B-tag is an epitope tag composed of a six-residue peptide, QYPALT, corresponding to a highly conserved region of VP7 core protein of the blue...

GenScript Rabbit Anti-E-tag [HRP] Polyclonal Antibody is highly purified from rabbit antiserum by immunoaffinity chromatography and then conjugated to horseradish peroxidase. GenScript Rabbit Anti-E-tag [HRP] Polyclonal Antibody is suitable for detecting fusion proteins that contain E-tags.

Chemokine (C-C motif) ligand 20 (CCL20) also known as liver activation regulated chemokine (LARC) or Macrophage Inflammatory Protein-3 (MIP3 alpha) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils. Additionally, it...

CHO-K1/Gqi5 is a CHO-K1 cell line stably expressing the chimeric Gqi5 alpha subunit protein which a chimeric Gq protein instead of the last five carboxyl-terminal amino acids from Gi. It is used as a host cell for transfection expression of Gi/o-coupled receptors, the constitutively expressed Gqi5...

Copper Tripeptide-1 acts as a signal and carrier peptide, promotes regular collagen, elastin, proteoglycan, and glycosaminoglycan synthesis, and provides anti-inflammatory and antioxidant responses. It also improves hair growth.

Cardiac Troponin I (cTnI) is a subtype of the troponin family that is commonly used as a marker for myocardial damage. Cardiac troponin I is specific for cardiac tissue and is detected in the serum only if myocardial injury has occurred. Because cardiac troponin I is a very sensitive and specific...

Platelet-derived growth factor (PDGF) presenting in serum but absent from plasma was first discovered in animal study by Lynch and co-workers in the late 1980s. It is a disulfide-linked dimer consisting of two peptides-chain A and chain B. PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is...

Adiponectin is an important adipokine involved in the control of fat metabolism and insulin sensitivity. It is synthesized exclusively by adipocytes and secreted into plasma. It antagonizes THF-alpha by negatively regulating its expression. It also inhibits endothelial NF-kappa-B signaling through a...

Polypeptide hormones secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and...

Histamine receptor family consists of four members, namely, H1, H2, H3, and H4. The histamine H4 receptor is the most recently identified G protein-coupled histamine receptor that binds to several neuroactive drugs, including amitriptyline and clozapine. So far, H4 receptors have been found only on...

Fractalkine, also named neurotactin, is a novel chemokine recently identified through bioinformatics. Fractalkine has a unique C-X3-C cysteine motif near the amino-terminus and is the first member of a fourth branch of the chemokine superfamily. Unlike other known chemokines, fractalkine is a type 1...
