Data show that Drosophila CASK is associated with both pre and postsynaptic membranes, and that loss of presynaptic CASK leads to less evoked synaptic transmission, fewer spontaneous synaptic events, and reduced synaptic vesicle cycling.
Full-length CASK-beta appears to have a unique role within central circuits that control motor output
Camguk localizes to synaptic regions of the brain and associates in an ATP-regulated manner with CaMKII to catalyze formation of a pool of calcium-insensitive CaMKII.
The results of this study support the involvement of CAKI in neurotransmitter release and nervous system function.
the Drosophila homolog of CASK/Camguk can act as a gain controller on the transition to calcium-independence in vivo.
Dneurexin (DNRX (显示 NRXN1 蛋白)) is important for locomotion through a genetic interaction with the scaffold protein (显示 HOMER1 蛋白), CAKI/CMG, the Drosophila homolog of vertebrate CASK.
The CASK as a novel regulator of Cav1.2 (显示 CACNA1C 蛋白) via a modulation of the voltage-gated calcium channel Cav1.2 (显示 CACNA1C 蛋白) open probability.
findings demonstrate that microcephaly with pontine and cerebellar hypoplasia (MICPCH) is a genetically heterogeneous condition, in which CASK inactivating mutations appear to account for the majority of MICPCH cases and with severer phenotypes, while the non-CASK mutation cases tend to have milder microcephaly
we provide a further characterization of genotype-phenotype correlations in CASK mutations and the presentation of nystagmus and the FGS4 phenotype.
During atrial dilation/remodeling, CASK expression was reduced but its localization remained unchanged.
we report a patient presenting with a complex phenotype consisting of severe, adult-onset, dilated cardiomyopathy, hearing loss and developmental delay, in which exome sequencing revealed two genetic variants that are inherited from a healthy mother: a novel missense variant in the CASK gene, mutations in which cause a spectrum of neurocognitive manifestations
In clinical specimens, CASK was over-expressed in tumors and H. pylori positive tissues, and its mRNA levels were inversely correlated with miR (显示 MLXIP 蛋白)-203 expression.
Data indicate that patients with low calcium/calmodulin-dependent serine protein kinase (CASK) staining had a significantly better survival compared to patients with high CASK staining.
The findings suggest that CASK and the truncated prestin (显示 SLC26A5 蛋白) splice isoform contribute to confinement of prestin (显示 SLC26A5 蛋白) to the basolateral region of the plasma membrane.
CASK regulates CaMKII (显示 CAMK2G 蛋白) autophosphorylation in a pathway required for memory formation.
a model whereby CASK recruits FRMD7 (显示 FRMD7 蛋白) to the plasma membrane to promote neurite outgrowth during development of the oculomotor neural network and that defects in this interaction result in nystagmus.
CASK phosphorylates neurexin, modulating the interaction of liprin-alpha with the CASK-neurexin1beta-Mint1 complex.
Ths data of this study implies that some phenotypic components of CASK heterozygous deletion mutation associated disorders represent systemic manifestation of metabolic stress.
DLG1 (显示 DLG1 蛋白) and CASK play critical cooperative roles in maintaining the nephron progenitor population, potentially via a mechanism involving effects on FGF signaling
Immunofluorescence shows colocalization of Cx43 (显示 GJA1 蛋白) and CASK in brain astrocytes.
CASK negatively regulates PMCA4b (显示 ATP2B4 蛋白) by directly binding to it and JAM-A (显示 F11R 蛋白) positively regulates it indirectly through CASK
Data show that CASK expression and the appropriate localization of DLG1 and LIN7c are not essential for either epithelial polarity or intestinal homeostasis in vivo.
Post-translational modifications to CASK are major regulatory steps leading to its proteasomal degradation.
CASK is transcribed in mouse testis and processing may play a role in the acquisition of spserm and sperm functions.
CASK and Dlg (显示 DLG4 蛋白) may act as a scaffold for organizing receptors and channels at the postsynaptic membrane of the neuromuscular junction.
findings suggest that Cask plays an important role in all retinal synapses
This gene encodes a calcium/calmodulin-dependent serine protein kinase. The encoded protein is a MAGUK (membrane-associated guanylate kinase) protein family member. These proteins are scaffold proteins and the encoded protein is located at synapses in the brain. Mutations in this gene are associated with FG syndrome 4, mental retardation and microcephaly with pontine and cerebellar hypoplasia, and a form of X-linked mental retardation. Multiple transcript variants encoding different isoforms have been found for this gene.
