Sequence analysis of the HPCA gene in 505 patients with dystonia did not reveal variants in the coding regions of HPCA.
hippocalcin forms oligomers upon calcium binding and directly interacts with VGCCs. The dystonia-causing mutations did not affect protein stability or folding. In common for both T71N and A190T mutants was an impaired calcium-dependent oligomerisation and increased intracellular calcium influx after KCl depolarisation.
None of the patients enrolled was found to carry HPCA mutations, rising suspicion that these probably represent a very rare cause of dystonia in childhood-adolescence.
Mutations in HPCA cause autosomal-recessive primary isolated dystonia.
analysis of a novel acetylation cycle of transcription co-activator Yes-associated protein that is downstream of Hippo pathway is triggered in response to SN2 alkylating agents
Hippocalcin is a sensitive Ca2+ sensor capable of responding to increases in intracellular Ca2+ concentration over the narrow dynamic range of 200-800 nM free Ca2+.
The structural factors affecting the binding of hippocalcin to phosphatidylinositol 4,5-bisphosphate at the cell surface and the Golgi apparatus are described.
Hippocalcin and MLK2 were colocalized in the halo of Lewy bodies in Parkinson disease patients, and neither protein was detected in normal pigmented neurons.
diminished hippocalcin expression does not contribute to Huntington disease-related neurodegeneration
results suggest that 7,8-Dihydroxy-4-methylcoumarin prevents glutamate-induced toxicity by scavenging free radicals and regulating hippocalcin expression.
Hippocalcin and KCNQ channels contribute to the kinetics of the slow afterhyperpolarization
Suggest that the maintenance of parvalbumin and hippocalcin levels by melatonin in ischemic injury contributes to the neuroprotective effect of melatonin against neuronal cell damage.
An age-dependent increase in neurodegeneration occurred in the gene-deleted mice, showing that hippocalcin contributes to neuronal viability during aging.
These results suggest that hippocalcin plays a crucial role in the Ca(2+)-signaling pathway that underlies long-lasting neural plasticity and that leads to spatial and associative memory.
These results suggest that hippocalcin plays an important role in calcium extrusion from neurons and, in turn, helps to protect them against calcium-dependent excitotoxin damage in the hippocampus.
hippocalcin-modulated ONE-GC transduction system exists in the olfactory receptor neuroepithelium. The Hpca-gene knock out studies demonstrate that the portion of this is about 30% of the total membrane guanylate cyclase transduction system
The protein encoded by this gene is a member of neuron-specific calcium-binding proteins family found in the retina and brain. This protein is associated with the plasma membrane. It has similarities to proteins located in the photoreceptor cells that regulate photosignal transduction in a calcium-sensitive manner. This protein displays recoverin activity and a calcium-dependent inhibition of rhodopsin kinase. It is identical to the rat and mouse hippocalcin proteins and thought to play an important role in neurons of the central nervous system in a number of species.
