| + | [[http://www.uniprot.org/uniprot/MCU_HUMAN MCU_HUMAN]] Mitochondrial inner membrane calcium uniporter that mediates calcium uptake into mitochondria. Mitochondrial calcium homeostasis plays key roles in cellular physiology and regulates cell bioenergetics, cytoplasmic calcium signals and activation of cell death pathways. Activity is regulated by MICU1 and MICU2 that stimulate and inhibit MCU activity, respectively. Regulates glucose-dependent insulin secretion in pancreatic beta-cells by regulating mitochondrial calcium uptake. Involved in buffering the amplitude of systolic calcium rises in cardiomyocytes.<ref>PMID:21685886</ref> <ref>PMID:21685888</ref> <ref>PMID:22822213</ref> <ref>PMID:22829870</ref> <ref>PMID:22904319</ref> <ref>PMID:23101630</ref> <ref>PMID:23178883</ref> <ref>PMID:24332854</ref> <ref>PMID:24560927</ref> [[http://www.uniprot.org/uniprot/EMRE_HUMAN EMRE_HUMAN]] Essential regulatory subunit of the mitochondrial calcium uniporter complex (uniplex), a complex that mediates calcium uptake into mitochondria (PubMed:24231807, PubMed:26774479, PubMed:27099988). Required to bridge the calcium-sensing proteins MICU1 and MICU2 with the calcium-conducting subunit MCU (PubMed:24231807). Plays a central role in regulating the uniplex complex response to intracellular calcium signaling (PubMed:27099988). Acts by mediating activation of MCU and retention of MICU1 to the MCU pore, in order to ensure tight regulation of the uniplex complex and appropriate responses to intracellular calcium signaling (PubMed:27099988).<ref>PMID:24231807</ref> <ref>PMID:26774479</ref> <ref>PMID:27099988</ref> | ||
