Subunit Structure: Component of the uniplex complex, composed of MCU, MCUB, MICU1, MICU2 and EMRE/SMDT1 (PubMed:24231807). Homooligomer (PubMed:21685886, PubMed:26341627). Forms a pentamer (By similarity). Heterooligomer with CCDC109B/MCUB; this inhibits channel activity (By similarity). Interacts with MICU1; MICU1 acts as an essential regulator for MCU (PubMed:21685886, PubMed:23101630, PubMed:23178883, PubMed:24332854, PubMed:26341627). Interacts with MCUR1 (PubMed:23178883, PubMed:26341627, PubMed:27184846, PubMed:26976564). Interacts with CCDC90B (PubMed:27184846). Interactions with MICU1 and MCUR1 are mutually exclusive (PubMed:23178883). Interacts with MICU2 (PubMed:26341627). Interacts with SLC25A23 (PubMed:24430870).
Post-translational Modifications: Phosphorylation by CaMK2 in heart leads to increased MCU current (PubMed:23051746, PubMed:25254481). The regulation of MCU by CaMK2 is however subject to discussion: another group was unable to reproduce these results (PubMed:25254480). Phosphorylated on tyrosines by PTK2B/PYK2, promoting oligomerization (PubMed:24800979).
Similarity: The N-terminal MCU domain is required for efficient Ca2+ uptake and for interaction with MCUR1. It is not required for targeting to the mitochondria, oligomerization, interaction with MICU1 and MICU2, or assembly of the uniplex complex.Forms a well-packed pentamer with an overall cylindrical shape. The inner core of the pentamer is formed with the second transmembrane region and the second coiled-coil region: while the transmembrane regions pack into a five-helix bundle having a largely polar pore across the membrane, the coiled-coil outside the membrane forms a pentamer with a hydrophobic core. The inner core is wrapped by the first transmembrane region through contacts between the first and the second transmembrane regions. The second transmembrane is followed by the inner juxtamembrane region (IJMH) that orients at a wide angle relative to the second transmembrane. The two core domains are held together on the periphery by the outer juxtamembrane helix (OJMH).The critical DXXE motif connecting the transmembrane regions forms a pentameric barrel that constitutes the mouth of the pore. Inside the barrel, two acidic residues are in position to form two carboxylate rings. In absence of SMDT1/EMRE regulator, the calcium ions cannot exit the channel, suggesting that SMDT1/EMRE-binding induces conformational rearrangements to allow calcium to exit. Belongs to the MCU (TC 1.A.77) family.

Predicted: 40 kDa
NCBI Description
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. [provided by RefSeq, Jul 2012]
Uniprot Description
Mitochondrial inner membrane calcium uniporter that mediates calcium uptake into mitochondria (PubMed:21685888, PubMed:21685886, PubMed:23101630, PubMed:22904319, PubMed:23178883, PubMed:22829870, PubMed:22822213, PubMed:24332854, PubMed:23755363, PubMed:26341627). Constitutes the pore-forming and calcium-conducting subunit of the uniporter complex (uniplex) (PubMed:23755363). Activity is regulated by MICU1 and MICU2. At low Ca2+ levels MCU activity is down-regulated by MICU1 and MICU2; at higher Ca2+ levels MICU1 increases MCU activity (PubMed:24560927, PubMed:26903221). Mitochondrial calcium homeostasis plays key roles in cellular physiology and regulates cell bioenergetics, cytoplasmic calcium signals and activation of cell death pathways. Involved in buffering the amplitude of systolic calcium rises in cardiomyocytes (PubMed:22822213). While dispensable for baseline homeostatic cardiac function, acts as a key regulator of short-term mitochondrial calcium loading underlying a 'fight-or-flight' response during acute stress: acts by mediating a rapid increase of mitochondrial calcium in pacemaker cells (PubMed:25603276). participates in mitochondrial permeability transition during ischemia-reperfusion injury (). Regulates glucose-dependent insulin secretion in pancreatic beta-cells by regulating mitochondrial calcium uptake (PubMed:22904319, PubMed:22829870). Mitochondrial calcium uptake in skeletal muscle cells is involved in muscle size in adults (). Regulates synaptic vesicle endocytosis kinetics in central nerve terminal (). Involved in antigen processing and presentation ().

Product Notes
The CCDC109A mcu (Catalog #AAA9609720) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The CCDC109A Antibody reacts with Human, Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's CCDC109A can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). WB: 1:1000-3000. Researchers should empirically determine the suitability of the CCDC109A mcu for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CCDC109A, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
