G-protein signaling_Regulation of RAC1 activity [score: 1 (0%)]
Ras-related C3 botulinum toxin substrate 1 (Rac1) belongs
to the Rho subgroup of a family of small GTP-binding proteins (G-proteins) called
monomeric G-proteins. Proteins belonging to the Rho subgroup are involved in cytoskeletal
control, regulation of the formation of the stress fibers, focal ...
Cytoskeleton remodeling_FAK signaling [score: 1 (0%)]
The biological importance of PTK2 protein tyrosine kinase 2, or Focal
adhesion kinase 1 (FAK1)-mediated signal transduction is
underscored by the fact that this tyrosine kinase plays a fundamental role in embryonic
development, in control of cell migration, cell cycle progression, and in apoptosis.
Binding ...
G-protein signaling_G-Protein alpha-12 signaling pathway [score: 1 (0%)]
Activation by ligands of G-protein coupled
receptors that interact with the trimeric G-protein alpha-12/beta/gamma
causes the exchange of GDP for GTP bound to G protein alpha subunits followed by
dissociation of the beta/gamma heterodimers. Free alpha and beta/gamma subunits are
active and ...
Cytoskeleton remodeling_Reverse signaling by ephrin B [score: 1 (0%)]
Ephrin receptors and Ephrins
are both membrane bound, and following their interaction and clustering, each can
transduce signals that regulate cell responses [1].
Ephrin receptors activate reverse signaling through their
Ephrin ligands ...
Cytoskeleton remodeling_Role of PKA in cytoskeleton reorganisation [score: 1 (0%)]
A wide variety of soluble signaling mediators utilize the Protein
kinase cAMP-dependent (PKA) pathway to regulate cellular
processes including intermediary metabolism, ion channel conductivity, and transcription.
PKA plays a central role in cytoskeletal regulation and cell
migration. ...
Signal transduction_Calcium signaling [score: 1 (0%)]
Calcium (Ca('2+)) is a
common second messenger that regulates many processes in the cell (e.g., contraction,
secretion, synaptic transmission, fertilization, nuclear pore regulation, transcription).
In cardiac myocytes and muscle cells, Ca('2+) concentrations
alternate between ...
Cytoskeleton remodeling_Regulation of actin cytoskeleton by Rho GTPases [score: 1 (0%)]
Ras homolog gene family, member A (RhoA) downstream
effector Rho-associated, coiled-coil containing protein kinase
(ROCK) directly phosphorylates LIM domain kinases 1 and 2
(LIMK1 and LIMK2) that in turn
phosphorylates Cofilin. Cofilin
exhibits Actin-depolymerizing ...
Cytoskeleton remodeling_Integrin outside-in signaling [score: 1 (0%)]
Integrins are heterodimeric adhesion receptors composed
of alpha- and beta-subunits. It is known that at least 18 distinct alpha subunits and 8
or more beta subunits lead to generation of 24 alpha/beta heterodimeric receptors. Most
integrins recognize extracellular matrix (ECM) proteins, such ...
Signal transduction_PKA signaling [score: 1 (0%)]
Protein kinase cAMP-dependent (PKA) is an enzyme playing
key role in a number of cellular processes. In its inactivated state,
PKA exists as a tetrameric complex of two catalytic subunits
(PKA-cat alpha and PKA-cat
beta) and two regulatory subunits (PKA-reg) (alpha ...
Development_Slit-Robo signaling [score: 1 (0%)]
Attractive and repulsive receptors regulate cell motility and attachment in axon
guidance, vascular growth, immune cell regulation and tumor progression. There is strong
evidence that development of the nervous and vascular systems is controlled by common
cues.
Semaphorins, Ephrins, SLITs ...
