GO:0005743,CC,"mitochondrial inner membrane","The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.",IEA
GO:0005744,CC,"mitochondrial inner membrane presequence translocase complex","The protein transport machinery of the mitochondrial inner membrane that contains three essential Tim proteins: Tim17 and Tim23 are thought to build a preprotein translocation channel while Tim44 interacts transiently with the matrix heat-shock protein Hsp70 to form an ATP-driven import motor.",IDA
GO:0006626,BP,"protein targeting to mitochondrion","The process of directing proteins towards and into the mitochondrion, usually mediated by mitochondrial proteins that recognize signals contained within the imported protein.",IDA
GO:0015266,MF,"protein channel activity","Enables the energy-independent facilitated diffusion, mediated by passage of proteins through a transmembrane aqueous pore or channel.",IBA
GO:0015450,MF,"P-P-bond-hydrolysis-driven protein transmembrane transporter activity","Primary active carrier-mediated transport of a protein across a membrane, driven by the hydrolysis of the diphosphate bond of inorganic pyrophosphate, ATP, or another nucleoside triphosphate. The transport protein may or may not be transiently phosphorylated, but the substrate is not phosphorylated.",IEA
GO:0030150,BP,"protein import into mitochondrial matrix","The import of proteins across the outer and inner mitochondrial membranes into the matrix. Unfolded proteins enter the mitochondrial matrix with a chaperone protein; the information required to target the precursor protein from the cytosol to the mitochondrial matrix is contained within its N-terminal matrix-targeting sequence. Translocation of precursors to the matrix occurs at the rare sites where the outer and inner membranes are close together.",IBA
GO:0031305,CC,"integral component of mitochondrial inner membrane","The component of the mitochondrial inner membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.",IDA
