Pathway: Signal Transduction (Homo sapiens)
Signal transduction is a process in which extracellular signals elicit changes in cell state and activity. Transmembrane receptors sense changes in the cellular environment by binding ligands, such as hormones and growth factors, or reacting to other types of stimuli, such as light. Stimulation of transmembrane receptors leads to their conformational change which propagates the signal to the intracellu

Pathway: Gastrin-CREB signalling pathway via PKC and MAPK (Homo sapiens)
Gastrin is a hormone whose main function is to stimulate secretion of hydrochloric acid by the gastric mucosa, which results in gastrin formation inhibition. This hormone also acts as a mitogenic factor for gastrointestinal epithelial cells. Gastrin has two biologically active peptide forms, G34 and G17.Gastrin gene expression is upregulated in both a number of pre-malignant conditions and in establish

Pathway: GPCR downstream signaling (Homo sapiens)
G protein-coupled receptors (GPCRs) are classically defined as the receptor, G-protein and downstream effectors, the alpha subunit of the G-protein being the primary signaling molecule. However, it has become clear that this greatly oversimplifies the complexities of GPCR signaling (see Gurevich & Gurevich, 2008). The beta:gamma G-protein dimer is also involved in downstream signaling (Smrcka, 2008), a

Pathway: GPCR ligand binding (Homo sapiens)
There are more than 800 G-protein coupled receptor (GPCRs) in the human genome, making it the largest receptor superfamily. GPCRs are also the largest class of drug targets, involved in virtually all physiological processes (Frederiksson 2003). GPCRs are receptors for a diverse range of ligands from large proteins to photons (Kristiansen et al. 2004) and have an equal diversity of ligand-binding mechan

Pathway: Signaling by GPCR (Homo sapiens)
G protein-coupled receptors (GPCRs; 7TM receptors; seven transmembrane domain receptors; heptahelical receptors; G protein-linked receptors [GPLR]) are the largest family of transmembrane receptors in humans, accounting for more than 1% of the protein-coding capacity of the human genome. All known GPCRs share a common architecture of seven membrane-spanning helices connected by intra- and extracellular

Pathway: G alpha (q) signalling events (Homo sapiens)
The classic signalling route for G alpha (q) is activation of phospholipase C beta thereby triggering phosphoinositide hydrolysis, calcium mobilization and protein kinase C activation. This provides a path to calcium-regulated kinases and phosphatases, GEFs, MAP kinase cassettes and other proteins that mediate cellular responses ranging from granule secretion, integrin activation, and aggregation in pl

Pathway: P2Y receptors (Homo sapiens)
P2Y receptors are a family of purinergic receptors, G protein-coupled receptors stimulated by nucleotides such as ATP, ADP, UTP, UDP and UDP-glucose. To date, 12 P2Y receptors have been cloned in humans (Abbracchio MP et al, 2006; Fischer W and Krugel U, 2007). P2Y receptors are present in almost all human tissues where they exert various biological functions based on their G-protein coupling. Purine n

Pathway: Nucleotide-like (purinergic) receptors (Homo sapiens)
Purinergic receptors (Burnstock G, 2006; Abbracchio MP et al, 2009) are a family of newly characterized plasma membrane molecules involved in several cellular functions such as vascular reactivity, apoptosis and cytokine secretion. The functions of these receptors are as yet only partially characterized. The family includes the GPCR P2Y purinergic receptors and adenosine P1 receptors. A third family me

Pathway: Class A/1 (Rhodopsin-like receptors) (Homo sapiens)
Rhodopsin-like receptors (class A/1) are the largest group of GPCRs and are the best studied group from a functional and structural point of view. They show great diversity at the sequence level and thus, can be subdivided into 19 subfamilies (Subfamily A1-19) based on a phylogenetic analysis (Joost P and Methner A, 2002). They represent members which include hormone, light and neurotransmitter recept
