G 蛋白偶联受体 (GPCR)是一大类进化相关的蛋白质,是细胞表面受体,可检测细胞外分子并激活细胞反应。G 蛋白偶联受体仅存在于真核生物中,包括酵母和鞭毛虫。结合和激活这些受体的配体包括光敏化合物、气味、信息素、激素和神经递质等。G蛋白偶联受体与许多疾病有关。例如精神疾病、代谢疾病、免疫疾病、心血管疾病、炎症、感觉障碍和癌症。因此GPCR是一个重要的药物靶点,在FDA批准的所有药物中,约有34% 靶向该家族的108个成员。
CC chemokine receptor (CCR) 8 (previously called CKR-L1 or TER1 and designated CD198), which is expressed on Th2 cells and eosinophils, has been implicated in allergic diseases. CCR8 may regulate monocyte chemotaxis and thymic cell line apoptosis and is alternative coreceptor with CD4 for HIV-1 infection. CCR8 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 30.62 kDa and the accession number is P51685-1.
Frizzled 5 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 17.6 kDa and the accession number is Q13467.
Renin Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 43.7 kDa and the accession number is P00797-1.
C-X-C chemokine receptor type 4 (CXCR4) is an alpha-chemokine receptor specific for stromal-derived-factor-1 (SDF-1 also called CXCL12), a molecule endowed with potent chemotactic activity for lymphocytes. This receptor is one of several chemokine receptors that HIV isolates can use to infect CD4+ T cells. CXCR4 stands out for its pleiotropic roles in both physiological and pathological conditions and it represents a crucial target in drug development. CXCL12 is the principal CXCR4 specific ligand and that the pro-inflammatory chemokine macrophage migration inhibitory factor (MIF) is also able to bind and activate CXCR4.
GPR37 (cathepsin Z) is an orphan receptor that belongs to the G-protein coupled receptor 1 family. G protein-coupled receptors are a large protein family comprised of transmembrane receptors that sense molecules outside the cell and activate inside signal transduction pathways and, ultimately, cellular responses. They only exist in eukaryotes, including yeast, choanoflagellates, and animals. These receptors are bonded and activated by light-sensitive compounds, odors, pheromones, hormones, and neurotransmitters. These ligands vary in size from small molecules to peptides to large proteins. G protein-coupled receptors are involved in many diseases and are also the target of approximately 40% of all modern medicinal drugs. GPR37 is expressed in the brain and spinal cord, and at lower levels in the testis, placenta, and liver, but no detectable expression is observed in any other tissue. GPR37 may have a unique functional role in the central nervous system.
Frizzled 10 Protein, Mouse, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 43 kDa and the accession number is Q149J3.
CXCR4 Protein, Human, Recombinant is expressed in HEK293 mammalian cells. The predicted molecular weight is 39.75 kDa and the accession number is P61073-1.
