FunFam 1599: Mitochondrial import receptor subunit TOM20-3

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
P-P-bond-hydrolysis-driven protein transmembrane transporter activity GO:0015450
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.
4 P82805 (/TAS) P82873 (/TAS) P82873 (/TAS) P82874 (/TAS)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
2 P82805 (/IPI) P82874 (/IPI)
Metal ion binding GO:0046872
Interacting selectively and non-covalently with any metal ion.
2 P82873 (/IDA) P82873 (/IDA)
P-P-bond-hydrolysis-driven protein transmembrane transporter activity GO:0015450
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.

There are 2 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein targeting to mitochondrion GO:0006626
The process of directing proteins towards and into the mitochondrion, usually mediated by mitochondrial proteins that recognize signals contained within the imported protein.
4 P82805 (/IMP) P82873 (/IMP) P82873 (/IMP) P82874 (/IMP)
Protein targeting to mitochondrion GO:0006626
The process of directing proteins towards and into the mitochondrion, usually mediated by mitochondrial proteins that recognize signals contained within the imported protein.
4 P82805 (/TAS) P82873 (/TAS) P82873 (/TAS) P82874 (/TAS)

There are 7 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Mitochondrial outer membrane translocase complex GO:0005742
A large complex of the mitochondrial outer membrane that mediates transport of proteins into all mitochondrial compartments.
4 P82805 (/IDA) P82873 (/IDA) P82873 (/IDA) P82874 (/IDA)
TIM23 mitochondrial import inner membrane translocase complex GO:0005744
The protein transport machinery of the mitochondrial inner membrane that typically transports proteins that possess a matrix-targeting N-terminal presequence. The TIM23 complex 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.
4 P82805 (/TAS) P82873 (/TAS) P82873 (/TAS) P82874 (/TAS)
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
3 P82873 (/IDA) P82873 (/IDA) P82874 (/IDA)
Mitochondrial outer membrane GO:0005741
The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.
3 P82873 (/IDA) P82873 (/IDA) P82874 (/IDA)
Mitochondrial inner membrane GO:0005743
The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.
3 P82873 (/IDA) P82873 (/IDA) P82874 (/IDA)
Cytosolic ribosome GO:0022626
A ribosome located in the cytosol.
2 P82873 (/IDA) P82873 (/IDA)
Vacuolar membrane GO:0005774
The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell.
