REACT_1031 (Reactome) When cAMP level rises, the PKA catalytic subunit (C subunit) released from the holoenzyme enters the nucleus by passive diffusion whereas termination of signaling to the nucleus involves an active mechanism. In the nucleus, the C subunit binds to the heat-stable protein kinase inhibitor (PKI), and this binding not only inactivates the C subunit but also by conformational change unveils a nuclear export signal in PKI which leads to export of the C-PKI complex from the nucleus.
REACT_12008 (Reactome) The IP3 receptor (IP3R) is an IP3-gated calcium channel. It is a large, homotetrameric protein, similar to other calcium channel proteins such as ryanodine. The four subunits form a 'four-leafed clover' structure arranged around the central calcium channel. Binding of ligands such as IP3 results in conformational changes in the receptor's structure that leads to channel opening.
REACT_12062 (Reactome) Diacylglycerol (DAG) positively regulates the autophosphorylation of protein kinase C-delta (PKC-delta), which stimulates ERK1/2 and triggers neurite outgrowth. DAG also stimulates the translocation of PKC from the cytosol to the plasma membrane. PKC-delta contributes to growth factor specificity and response to neuronal cells by promoting cell-type-specific differences in growth factor signalling. DAG can also activate PKC-epsilon in the same manner.
REACT_12074 (Reactome) IP3 promotes the release of intracellular calcium.
REACT_12078 (Reactome) Inositol 1,4,5-triphosphate (IP3) is a second messenger produced by phospholipase C (PLC) metabolism of phosphoinositol 4,5-bisphosphate (PIP2) (Canossa et al. 2001).
REACT_12602 (Reactome) Upon increase in calcium concentration, calmodulin (CaM) is activated by binding to four calcium ions.
REACT_15320 (Reactome) Autophosphorylation of the N-terminus Ser12-Ser13 is required for full activation after Ca2+/calmodulin binding and phosphorylation of the Ca2+/calmodulin-bound enzyme on Thr200 by a Ca2+/calmodulin-dependent protein kinase kinase.
REACT_1532 (Reactome) The four protein kinase A (PKA) regulatory subunit isoforms differ in their tissue specificity and functional characteristics. The specific isoform activated in response to glucagon signalling is not known. The PKA kinase is a tetramer of two regulatory and two catalytic. The regulatory subunits block the catalytic subunits. Binding of cAMP to the regulatory subunit leads to the dissociation of the tetramer into two active dimers made up of a regulatory and a catalytic subunit.
REACT_15332 (Reactome) The calmodulin:CaMK IV complex enters the nucleus.
REACT_15339 (Reactome) CaMKIV becomes fully activated after a three-step mechanism: Upon a transient increase in intracellular calcium, calcium-bound calmodulin (Ca2+/CaM) binds to its autoregulatory domain, which relieves intersteric inhibition. An activating protein kinase, calcium/calmodulin-dependent protein kinase kinase (CaMKK), binds to the Ca2+/CaM:CaMKIV complex and phosphorylates CaMKIV on a threonine residue in the activation loop. After full activation by the three-step mechanism mentioned above, the activity of CaMKIV becomes autonomous and no longer requires bound Ca2+/CaM. This activity is required for CaMKIV-mediated transcriptional regulation. The CaMKIV-associated PP2A then dephosphorylates CaMKIV, thereby terminating autonomous activity and CaMKIV-mediated gene transcription.
REACT_15377 (Reactome) cAMP-dependent protein kinase A (PKA) phosphorylates in vitro CREB at a specific residue, serine 133; Phosphorylation of Ser133 is required for signal-induced transcription in vivo.
REACT_15415 (Reactome) CREB readily dimerizes.
REACT_15422 (Reactome) GRK2 is a Serine/Threonine kinase. G-protein-coupled receptor kinases (GRKs) are important regulators of G-protein-coupled receptor function. Binding of calmodulin to GRK2 results in inhibition of the kinase activity. This inhibition is almost completely abolished when GRK2 is phosphorylated by PKC.
REACT_15427 (Reactome) The cAMP-responsive element binding protein (CREB), a key regulator of gene expression, is activated by phosphorylation on Ser-133. Several different protein kinases possess the capability of driving this phosphorylation, making it a point of potential convergence for multiple intracellular signaling cascades. Work in neurons has indicated that physiologic synaptic stimulation recruits a fast calmodulin kinase IV (CaMKIV)-dependent pathway that dominates early signaling to CREB.
REACT_15450 (Reactome) Increased Ca2+ levels, acting via calmodulin, can activate PDE which can then act upon cAMP.
REACT_15534 (Reactome) GRK2 is phosphorylated at serine 29 in vitro and in vivo by the alpha, gamma and delta isoforms of PKC. PKC-mediated phosphorylation at Ser29 increases GRK2 kinase activity towards GPCR substrates, contributing to GPCR desensitization. Phosphorylation at Ser29, which falls within the calmodulin-binding region of GRK2, abolishes the inhibitory effect of calmodulin on GRK2 kinase activity.
REACT_1963 (Reactome) Adenylate cyclase is responsive to calcium and calmodulin and produces cAMP. One important physiological role for Calmodulin is the regulation of adenylylcyclases. Four of the ten known adenylylcyclases are calcium sensitive, in particular type 8 (AC8).
REACT_827 (Reactome) Phosphodiesterases (PDEs) hydrolyze cAMP and cGMP, inactivating these second messengers.
