CC   -!- FUNCTION: Essential regulatory subunit of the mitochondrial calcium
CC       uniporter complex (uniplex), a complex that mediates calcium uptake
CC       into mitochondria (PubMed:24231807, PubMed:26774479, PubMed:27099988).
CC       Required to bridge the calcium-sensing proteins MICU1 and MICU2 with
CC       the calcium-conducting subunit MCU (PubMed:24231807). Plays a central
CC       role in regulating the uniplex complex response to intracellular
CC       calcium signaling (PubMed:27099988). Acts by mediating activation of
CC       MCU and retention of MICU1 to the MCU pore, in order to ensure tight
CC       regulation of the uniplex complex and appropriate responses to
CC       intracellular calcium signaling (PubMed:27099988).
CC       {ECO:0000269|PubMed:24231807, ECO:0000269|PubMed:26774479,
CC       ECO:0000269|PubMed:27099988}.
CC   -!- SUBUNIT: Component of the uniplex complex, composed of MCU, MCUB,
CC       MICU1, MICU2 and EMRE/SMDT1 (PubMed:24231807). Interacts (via the
CC       transmembrane region) with MCU (via the first transmembrane region);
CC       the interaction is direct (PubMed:27099988). Interacts (via the poly-
CC       Asp region) with MICU1 (via polybasic region); the interaction is
CC       direct (PubMed:27099988). Interacts (via its C-terminal poly-Asp tail)
CC       with MCUR1; the interaction is direct (PubMed:27184846). Unprocessed
CC       form interacts (via transit peptide) with MAIP1 (PubMed:27642048).
CC       {ECO:0000269|PubMed:24231807, ECO:0000269|PubMed:27099988,
CC       ECO:0000269|PubMed:27184846, ECO:0000269|PubMed:27642048}.
CC   -!- INTERACTION:
CC       Q9H4I9; Q8NE86: MCU; NbExp=7; IntAct=EBI-11908005, EBI-6552124;
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000269|PubMed:24231807, ECO:0000269|PubMed:26774479,
CC       ECO:0000269|PubMed:27099988, ECO:0000269|PubMed:27642048}; Single-pass
CC       membrane protein {ECO:0000269|PubMed:24231807,
CC       ECO:0000269|PubMed:27099988}. Note=MAIP1 is required to assist sorting
CC       of EMRE/SMDT1 into mitochondrion by protecting EMRE/SMDT1 against
CC       protein degradation by YME1L1, thereby ensuring SMDT1/EMRE maturation
CC       by the mitochondrial processing peptidase (PMPCA and PMPCB)
CC       (PubMed:27642048). {ECO:0000269|PubMed:27642048}.
CC   -!- DOMAIN: The GXXXX[G/A/S] motif at the C-terminal part of the
CC       transmembrane region mediates interaction with MCU and is required to
CC       activate the calcium-conducting pore in the uniporter complex.
CC       {ECO:0000269|PubMed:27099988}.
CC   -!- DOMAIN: The poly-Asp region at the C-terminus mediates interaction with
CC       the polybasic region of MICU1. {ECO:0000269|PubMed:27099988}.
CC   -!- PTM: Undergoes proteolytic degradation in neurons: degraded by AFG3L2
CC       before SMDT1/EMRE assembly with the uniporter complex, limiting the
CC       availability of SMDT1/EMRE for MCU assembly and promoting efficient
CC       assembly of gatekeeper subunits with MCU (PubMed:27642048).
CC       {ECO:0000269|PubMed:27642048}.
CC   -!- SIMILARITY: Belongs to the SMDT1/EMRE family. {ECO:0000305}.
CC   -!- CAUTION: A publication reports an opposite topology (PubMed:26774479).
CC       However, 3 different articles, 2 in human and one in mouse, confirm the
CC       topology shown in this entry (PubMed:27099988, PubMed:27642048).
CC       {ECO:0000269|PubMed:26774479, ECO:0000269|PubMed:27099988,
