Our experiments provide novel details about how MCU/EMRE is regulated by MICU1 (show MICU1 Proteins) and an original approach to investigate MCU/EMRE activation in intact cells.
Data suggest that MCU regulator (EMRE) might be a structural factor for opening of the mitochondrial calcium uniporter (MCU)-forming pore.
results suggest that N terminal domain of MCU is essential for the modulation of MCU function, although it does not affect the uniplex formation
MCU-VDAC1 (show VDAC1 Proteins) complex regulates mitochondrial Ca(2 (show CA2 Proteins)+) uptake and oxidative stress-induced (show SQSTM1 Proteins) apoptosis
Loss of heterozygosity of MCU gene on chromosome 10q is associated with pancreatic cancer.
Studies indicate the existence of an inner mitochondrial protein (show COX6B2 Proteins) termed the mitochondrial calcium uniporter for calcium transport.
analyses establish that MCU encodes the pore-forming subunit of the uniporter channel
MCU plays a critical role in breast cancer cell migration by regulating store-operated Ca(2 (show CA2 Proteins)) entry.
SLC25A23 (show SLC25A24 Proteins) augments mitochondrial Ca(2 (show CA2 Proteins)) uptake, interacts with MCU, and induces oxidative stress-mediated cell death.
We review not only the biochemical identities and structures of the proteins required for mitochondrial Ca2 (show CA2 Proteins)+ uptake but also their implications in different physiopathological contexts. [review]
the Mcu-regulating Micu gene family profile differs substantially between neurons and astrocytes, while expression of Mcu itself is markedly different between CA3 (show CA3 Proteins) and CA1 (show CA1 Proteins) regions in the adult hippocampus.
Absence of MCU expression does not affect basal cardiac function at either 12 or 20months of age in knockout mice.
MCU is required to match energetics with contractile demand during stress. Deletion of Mcu protects against myocardial IR injury.
Mice lacking MCU in the heart show no pathology. MCU selectively mediates acute mitochondria Ca2 (show CA2 Proteins)+ loading to augment ATP synthesis.
MCU is necessary for complete physiological heart rate acceleration
Chromatin immunoprecipitation and promoter reporter analyses revealed that the Ca2 (show CA2 Proteins)+ -regulated transcription factor CREB (show CREB1 Proteins) (cyclic adenosine monophosphate response element-binding protein) directly bound the MCU promoter and stimulated expression.
chronic myocardial MCU inhibition leads to previously unanticipated compensatory changes.
Tetrodotoxin-sensitive mitochondrial Ca(2 (show CA2 Proteins)+) influx was largely blocked by knockdown of MCU expression.
Characterization of MCU deficient mice indicates that acute alterations in mitochondrial matrix calcium can regulate mammalian physiology.
This gene encodes a calcium transporter that localizes to the mitochondrial inner membrane. The encoded protein interacts with mitochondrial calcium uptake 1. Alternative splicing results in multiple transcript variants.
