PFAM accession number:PF10161
Interpro abstract (IPR018782):

Essential MCU regulator (EMRE) is a component of the mitochondrial calcium uniporter complex in metazoa, a complex that mediates calcium uptake into mitochondria. It bridges the calcium-sensing components of the complex, MICU1 and MICU2, and the pore-forming subunit MCU, and it is essential for the complex uniporter activity [ (PUBMED:24231807) ].

GO process:calcium import into the mitochondrion (GO:0036444), mitochondrial calcium ion homeostasis (GO:0051560)
GO component:uniplex complex (GO:1990246)
