Does not form functional calcium channels by itself. Mitochondrial calcium homeostasis plays key roles in cellular physiology and regulates cell bioenergetics, cytoplasmic calcium signals and activation of cell death pathways. {ECO:0000250|UniProtKB:Q810S1}. |DUF607| |uniplex complex| |calcium import into the mitochondrion| |calcium channel inhibitor activity| |intrinsic component of membrane| |mitochondrial calcium ion transmembrane transport| |calcium channel complex| |mitochondrial calcium ion homeostasis| |ion channel activity| |integral component of mitochondrial inner membrane| |calcium ion import| |cytosolic calcium ion transport| |mitochondrial transmembrane transport| |calcium ion transmembrane transport| |mitochondrial transport| |calcium ion transport| |divalent metal ion transport| |divalent inorganic cation transport| |mitochondrial inner membrane| |cellular calcium ion homeostasis| |calcium ion homeostasis| |cellular divalent inorganic cation homeostasis| |divalent inorganic cation homeostasis| |cellular metal ion homeostasis| |inorganic cation transmembrane transport| |cation transmembrane transport| |metal ion homeostasis| |cellular cation homeostasis| |metal ion transport| |cellular ion homeostasis| |inorganic ion transmembrane transport| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |ion homeostasis| |cation transport| |cellular homeostasis| |ion transmembrane transport| |chemical homeostasis| |mitochondrion| |transmembrane transport| |ion transport| |homeostatic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp307|Rapamycin 2μM plus Cyclosporin-A 3μM R07 exp307]]|1.8| |[[:results:exp45|Docetaxel 0.002μM R01 exp45]]|1.86| |[[:results:exp141|Nifurtimox 1μM R03 exp141]]|1.87| |[[:results:exp54|Taxol 0.002μM R01 exp54]]|1.95| |[[:results:exp40|2-Methoxyestradiol 0.2μM R01 exp40]]|2.17| No correlation found to any other genes in chemogenomics.
