H-SGATGVAIK^-OH
Peptide H-SGATGVAIK^-OH is a Research Peptide with significant interest within the field academic and medical research. This peptide is available for purchase at Cymit Quimica in multiple sizes and with a specification of your choice.Syntide 2
Syntide-2 is a substrate peptide which was specifically designed to be homologous to site 2 in glycogen synthase. Syntide-2 is therefore phosphorylated by Ca2+ calmodulin-dependent protein kinase II as well as other calcium dependant kinases and protein kinase C. Synthase-2 can also be phosphorylated by CAMP-dependent protein kinase and to a lesser extent- phosphorylase kinase, but not by myosin light chain kinase.

PTH (1-34) human
PTH 1-34, is a biologically active peptide fragment of parathyroid hormone (PTH). PHT 1-34 has been shown to enhance bone fracture healing by promoting osteogenesis. PTH 1-34 also has chondrogenic properties.PTH is an 84-amino-acid polypeptide hormone (PTH 1-84) which is secreted by the parathyroid glands along with its fragments (such as PTH 1-34 and PTH 7-84). PTH increases calcium and decrease phosphate levels in the blood and the abundance of PTH-derived peptides is regulated by blood calcium levels. PTH inhibits the bone growth-promoting activity of osteoblasts and induces osteoclasts to resorb bone and release calcium and phosphate ions into the blood. PTH binds to and activates the receptor parathyroid hormone receptor 1 (PTHR1). PTHR1 is a G-protein-coupled receptor (GPCR) which regulates mineral ion homeostasis, bone turnover and skeletal development.Couleur et forme :PowderMasse moléculaire :4,115.1 g/molGalanin Human
Galanin is a neuropeptide synthesised and released by the brainstem locus coeruleus (LC). Galanin is expressed in most LC neurons in rodents and humans. Galanin has been shown to inhibit LC activity by hyperpolarising LC neurons, suppressing their spontaneous firing rate, and enhancing alpha2-adrenergic receptor-mediated negative feedback. Galanin is also a potent trophic and neuroprotective factor throughout the nervous system.Galanin is widely distributed from the central nervous system, peripheral regions and endocrine system. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes GalR1-3 which are G protein-coupled receptors and are inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway but unlike GalR1 there is detectable inositol phosphate production. GalR3 is associated with the Gα pathway, activation of the receptor leads to cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against a variety of physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied in relation to Alzheimer's disease and galaninergic neurons have been shown to be spared in late-stage Alzheimer's relative to non-galaninergic neurones.Masse moléculaire :3,157.41 g/molAngiotensin I-converting enzyme inhibitor 10

Formule :C13H25N3O4Masse moléculaire :287.36 g/mol(PFR)2-[Rh110]
Soybean trypsin inhibitor inhibits trypsin, factor Xa, plasmin, and plasma kallikrein activity in serum-free cell culture media. It does not inhibit metallo-, cysteine, aspartic proteases, or tissue kallikrein (serine proteases).Kallikreins (KLKs) are a large family of secreted serine proteases with either trypsin-like or chymotrypsin-like specificity which carry out many biological functions. The KLK proteases are involved in pathways that regulate skin desquamation, tooth enamel formation, kidney function, seminal liquefaction, synaptic neural plasticity, and brain function. Disruptions in the function of KLK activity has been linked to several pathologies, including respiratory diseases, neurodegeneration, anxiety, schizophrenia, skin-barrier dysfunction, pathological inflammation, and cancer.Masse moléculaire :1,130.6 g/molRelaxin 3 B1-22R amide
Relaxin-3 is part of the insulin/relaxin superfamily with various roles, including appetite, stress, and addiction. Relaxin-3 binds to its cognate receptor relaxin family peptide 3 receptor (RXFP3). B1-22R is a single-chain relaxin-3 antagonist for RXFP3 no interaction is found with RXFP1 or RXFP4. B1-22R is a truncation of the B-chain of relaxin-3 and the addition of an arginine residue at the C-terminus-B1-22R acts as a RXFP3 antagonist. B1-22R has been used to perform structural analysis relationships (SARs) and residue scanning to understand the critical residues and conformation of the interaction between B1-22R and RXFP3. B1-22R can generate more potent analogs of relaxin-3 that are more stable and serve as models for drug design targeting the relaxin-3 receptor for regulation of addiction, stress, and appetite.B1-22R is provided in the amide form.Masse moléculaire :2,620.5 g/molCBL (167-180) Light
CBL (167-180) is derived from the CBL E3 ubiquitin ligase which targets receptor tyrosine kinases to lysosome degradation. CBL and its family member CBL-B are expressed in hematopoietic cells and as E3 ubiquitin ligases they contain a tyrosine kinase domain and an RF domain joined by a linker domain. The function of the RF domain is to transfer ubiquitin from E2 ubiquitin-conjugating enzymes onto the target protein which is often phosphorylated. Consequently the ubiquitinated substrate, the receptor tyrosine kinases, are ultimately targeted to the lysosome for degradation.EGFR is an example of a receptor tyrosine kinase whose activation is prevented by CBL and CBL-B when they bind and recruit GRb2, the adapter protein to EGFR. Consequently the ubiquitinylation of EGFR occurs and targets it for recognition by the endosomal protein complex and then lysosome degradation.It has also been found that the CBL family can negatively regulate through ubiquitinylation, PI 3-kinases, Rap G-protein guanine nucleotide exchange factor (GEF), C3G and Rho GTPase GEF Vav which are all non-receptors.If CBL becomes non-functional it can be associated with malignancies such as acute myeloid leukemia and myelodysplastic syndrome.
Masse moléculaire :1,540.8 g/molBombesin
Bombesin was originally isolated from the skin of the european fire-bellied toad (Bombina bombina) and has two known homologues Neuromedin B (NMB) and gastrin-releasing peptide (GRP).Bombesin-like peptides are involved in many physiological functions including: regulation of food intake- anxiety and fear-related behaviour, thermoregulation, stress response, learning and memory and in the stimulation of smooth muscle contraction. Bombesin is also a tumour marker for small cell carcinoma in the lung, gastric cancer, pancreatic cancer, and neuroblastoma.The receptors for these two peptides are known as bombesin receptor type 1 (BB1 also known as NMB receptor) and bombesin receptor type 2 (BB2 also known as GRP receptor). Bombesin shows high affinity to both of these receptor subtypes. These bombesin-like peptides and their receptors are widely distributed in the central nervous system (CNS) and gastrointestinal (GI) tract.This peptide contains an N-terminal pyroglutamyl to prevent the intramolecular cyclisation of the N-terminal of glutamine to N-pyroglutamate (pGlu).Masse moléculaire :1,618.8 g/molCys-TAT(48-60)
