CC   -!- FUNCTION: Mitochondrial glycine transporter that imports glycine into
CC       the mitochondrial matrix. Plays an important role in providing glycine
CC       for the first enzymatic step in heme biosynthesis, the condensation of
CC       glycine with succinyl-CoA to produce 5-aminolevulinate (ALA) in the
CC       mitochondrial matrix. Required during erythropoiesis.
CC       {ECO:0000255|HAMAP-Rule:MF_03064}.
CC   -!- FUNCTION: May play a role as pro-apoptotic protein that induces
CC       caspase-dependent apoptosis. {ECO:0000250|UniProtKB:Q91XD8}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=glycine(in) = glycine(out); Xref=Rhea:RHEA:70715,
CC         ChEBI:CHEBI:57305; Evidence={ECO:0000250|UniProtKB:Q96DW6};
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_03064}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_03064}.
CC   -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC       SLC25A38 subfamily. {ECO:0000255|HAMAP-Rule:MF_03064}.
