Descriptions Names[Advanced Search]

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). Enables the directed movement of proteins into, out of, within or between cells. Catalysis of the transfer of a macromolecule from one side of the membrane to the other. Catalysis of the transfer of a protein from one side of a membrane to the other. Catalysis of energy-independent facilitated diffusion, mediated by passage of proteins through a transmembrane aqueous pore or channel. Catalysis of the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient. Catalysis of 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.
