Phosphatidylinositol 4,5-Diphosphate 106-110 calmodulin 1 Homo sapiens 273-283 22989896-0 2012 PtdIns(4,5)P2 interacts with CaM binding domains on TRPM3 N-terminus. Phosphatidylinositol 4,5-Diphosphate 0-13 calmodulin 1 Homo sapiens 29-32 22643219-5 2012 The calmodulin-deficient channel has a reduced affinity towards PIP2. Phosphatidylinositol 4,5-Diphosphate 64-68 calmodulin 1 Homo sapiens 4-14 21883766-3 2011 CaM inhibition increased Rac1 binding to PIP5K and induced an extensive phosphatidylinositol 4,5-bisphosphate (PI4,5P(2) )-positive tubular membrane network. Phosphatidylinositol 4,5-Diphosphate 72-109 calmodulin 1 Homo sapiens 0-3 33041849-0 2020 Two KCNQ2 Encephalopathy Variants in the Calmodulin-Binding Helix A Exhibit Dominant-Negative Effects and Altered PIP2 Interaction. Phosphatidylinositol 4,5-Diphosphate 114-118 calmodulin 1 Homo sapiens 41-51 9545238-5 1998 Accordingly, the AKAP79 basic regions mediate binding to membrane vesicles containing acidic phospholipids including phosphatidylinositol-4, 5-bisphosphate [PtdIns(4,5)P2] and this binding is regulated by phosphorylation and calcium-calmodulin. Phosphatidylinositol 4,5-Diphosphate 117-155 calmodulin 1 Homo sapiens 233-243 9545238-5 1998 Accordingly, the AKAP79 basic regions mediate binding to membrane vesicles containing acidic phospholipids including phosphatidylinositol-4, 5-bisphosphate [PtdIns(4,5)P2] and this binding is regulated by phosphorylation and calcium-calmodulin. Phosphatidylinositol 4,5-Diphosphate 157-170 calmodulin 1 Homo sapiens 233-243 2994657-1 1985 The calmodulin antagonists trifluoperazine, chlorpromazine, perphenazine, promazine, tamoxifen and the naphthalene sulfonamide derivatives W7 and W13 increased the level of 32P-incorporation into human platelet PIP and PIP2. Phosphatidylinositol 4,5-Diphosphate 219-223 calmodulin 1 Homo sapiens 4-14 9341159-10 1997 We discuss the biological implications of this switch mechanism, speculating that an increase in the level of Ca2+-calmodulin could rapidly release phosphatidylinositol 4, 5-bisphosphate that previous work has suggested is sequestered in lateral domains formed by MARCKS and MARCKS-(151-175). Phosphatidylinositol 4,5-Diphosphate 148-186 calmodulin 1 Homo sapiens 115-125 33310856-4 2020 Combined electrophysiology and molecular dynamics network analysis suggest that VSD transition into the fully activated state allows PIP2 to compete with CaM for binding to VSD. Phosphatidylinositol 4,5-Diphosphate 133-137 calmodulin 1 Homo sapiens 154-157 27933776-7 2016 The findings show that CaM does stimulate PI3K lipid kinase activity by binding MARCKS and displacing it from PIP2 headgroups, thereby releasing free PIP2 that recruits active PI3K to the membrane and serves as the substrate for the generation of PIP3. Phosphatidylinositol 4,5-Diphosphate 110-114 calmodulin 1 Homo sapiens 23-26 32560560-2 2020 The aim of this study was to characterise interactions between the TRP cation channel subfamily melastatin member 4 (TRPM4) and endogenous intracellular modulators-calcium-binding proteins (calmodulin (CaM) and S100A1) and phosphatidylinositol 4, 5-bisphosphate (PIP2). Phosphatidylinositol 4,5-Diphosphate 223-261 calmodulin 1 Homo sapiens 190-200 32560560-2 2020 The aim of this study was to characterise interactions between the TRP cation channel subfamily melastatin member 4 (TRPM4) and endogenous intracellular modulators-calcium-binding proteins (calmodulin (CaM) and S100A1) and phosphatidylinositol 4, 5-bisphosphate (PIP2). Phosphatidylinositol 4,5-Diphosphate 263-267 calmodulin 1 Homo sapiens 190-200 27933776-5 2016 This study asks whether calmodulin (CaM), which is known to directly bind MARCKS, also stimulates PIP3 production by releasing free PIP2. Phosphatidylinositol 4,5-Diphosphate 132-136 calmodulin 1 Homo sapiens 24-34 27933776-5 2016 This study asks whether calmodulin (CaM), which is known to directly bind MARCKS, also stimulates PIP3 production by releasing free PIP2. Phosphatidylinositol 4,5-Diphosphate 132-136 calmodulin 1 Homo sapiens 36-39 24349250-13 2013 These results suggest that a rise in intracellular calcium induces a change in the configuration of CaM-KCNQ binding, which leads to the reduction of KCNQ affinity for PIP2 and subsequent current suppression. Phosphatidylinositol 4,5-Diphosphate 168-172 calmodulin 1 Homo sapiens 100-103 26359296-3 2015 Live-cell fluorescence energy transfer measurements and direct binding studies indicate that remote coiled-coil formation creates conditions for different CaM interaction modes, each conferring different PIP2 dependency to Kv7.2 channels. Phosphatidylinositol 4,5-Diphosphate 204-208 calmodulin 1 Homo sapiens 155-158 26359296-4 2015 Disruption of coiled-coil formation by epilepsy-causing mutation decreases apparent CaM-binding affinity and interrupts CaM influence on PIP2 sensitivity. Phosphatidylinositol 4,5-Diphosphate 137-141 calmodulin 1 Homo sapiens 120-123 25543978-8 2015 We found that this region overlaps with previously identified calmodulin and PIP2 binding sites and that S100A1 competes with calmodulin and PIP2 for this binding site.
