| GO term | GO name | GO namespace | GO def |
| GO:0022857 | transmembrane transporter activity | molecular_function | Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. [GOC:jid, GOC:mtg_transport, ISBN:0815340729] |
| GO:0042277 | peptide binding | molecular_function | Binding to a peptide, an organic compound comprising two or more amino acids linked by peptide bonds. [GOC:jl] |
| GO:0030150 | protein import into mitochondrial matrix | biological_process | 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. [ISBN:0716731363] |
| GO:0005215 | transporter activity | molecular_function | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. [GOC:ai, GOC:dgf] |
| GO:0098796 | membrane protein complex | cellular_component | Any protein complex that is part of a membrane. [GOC:dos] |
| GO:0022829 | wide pore channel activity | molecular_function | Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0033218 | amide binding | molecular_function | Binding to an amide, any derivative of an oxoacid in which an acidic hydroxy group has been replaced by an amino or substituted amino group. [GOC:mah] |
| GO:0098798 | mitochondrial protein-containing complex | cellular_component | A protein complex that is part of a mitochondrion. [GOC:dos] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0008320 | protein transmembrane transporter activity | molecular_function | Enables the transfer of a protein from one side of a membrane to the other. [GOC:jl] |
| GO:0015267 | channel activity | molecular_function | Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0006811 | ion transport | biological_process | The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:ai] |
| GO:0005488 | binding | molecular_function | The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. [GOC:ceb, GOC:mah, ISBN:0198506732] |
| GO:0032991 | protein-containing complex | cellular_component | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. [GOC:dos, GOC:mah] |
| GO:0022803 | passive transmembrane transporter activity | molecular_function | Enables the transfer of a single solute from one side of a membrane to the other by a mechanism involving conformational change, either by facilitated diffusion or in a membrane potential dependent process if the solute is charged. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0005048 | signal sequence binding | molecular_function | Binding to a signal sequence, a specific peptide sequence found on protein precursors or mature proteins that dictates where the mature protein is localized. [GOC:ai] |
