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: Signaling by Rho GTPases (Homo sapiens)
The Rho family of small guanine nucleotide binding proteins is one of five generally recognized branches of the Ras superfamily. Like most Ras superfamily members, typical Rho proteins function as binary switches controlling a variety of biological processes. They perform this function by cycling between active GTP-bound and inactive GDP-bound conformations. Mammalian Rho GTPases include RhoA, RhoB and

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: Signalling by NGF (Homo sapiens)
Neurotrophins (NGF, BDNF, NT-3, NT-4/5) play pivotal roles in survival, differentiation, and plasticity of neurons in the peripheral and central nervous system. They are produced, and secreted in minute amounts, by a variety of tissues. They signal through two types of receptors: TRK tyrosine kinase receptors (TRKA, TRKB, TRKC), which specifically interact with the different neurotrophins, and p75NTR,

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: p75 NTR receptor-mediated signalling (Homo sapiens)
Besides signalling through the tyrosine kinase receptors TRK A, B, and C, the mature neurotrophins NGF, BDNF, and NT3/4 signal through their common receptor p75NTR. NGF binding to p75NTR activates a number of downstream signalling events controlling survival, death, proliferation, and axonogenesis, according to the cellular context. p75NTR is devoid of enzymatic activity, and signals by recruiting othe

Pathway: Rho GTPase cycle (Homo sapiens)
The cycling of Rho GTPases is tightly controlled by three classes of protein. These are (1) guanine nucleotide dissociation inhibitors or GDIs, which maintain Rho proteins in an inactive state in the cytoplasm, (2) guanine nucleotide exchange factors or GEFs, which destabilize the interaction between Rho proteins and their bound nucleotide, the net result of which is the exchange of bound GDP for the m

Pathway: G alpha (12/13) signalling events (Homo sapiens)
The G12/13 family is probably the least well characterized subtype, partly because G12/13 coupling is difficult to determine when compared with the other subtypes which predominantly rely on assay technologies that measure intracellular calcium. The G12/13 family are best known for their involvement in the processes of cell proliferation and morphology, such as stress fiber and focal adhesion formation

Pathway: Cell death signalling via NRAGE, NRIF and NADE (Homo sapiens)
p75NTR is a key regulator of neuronal apoptosis, both during development and after injury. Apoptosis is triggered by binding of either mature neurotrophin or proneurotrophin (proNGF, proBDNF). ProNGF is at least 10 times more potent than mature NGF in inducing apoptosis. TRKA signalling protects neurons from apoptosis. The molecular mechanisms involved in p75NTR-apoptosis are not well understood. The
