Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells. Modulates the activity of a channel. A channel catalyzes energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage. Functions in the storage of nutritious substrates. The molecular function that accepts an input of one form and creates an output of a different form. Any molecular entity that serves as an electron acceptor and electron donor in an electron transport system. Modulates the activity of the proteasome complex. The proteasome complex performs regulated ubiquitin-dependent cytosolic and nuclear proteolysis. Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. Assists in the delivery of metal ions to target proteins or compartments. Any molecular function involved in the initiation, activation, perpetuation, repression or termination of polypeptide synthesis at the ribosome. Providing the environmental signal that initiates the directed movement of a motile cell or organism towards a higher concentration of that signal. Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. Providing the environmental signal that initiates the directed movement of a motile cell or organism towards a lower concentration of that signal. The action of a molecule that contributes to the structural integrity of a complex or assembly within or outside a cell. The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. Plays a role in regulating transcription; may bind a promoter or enhancer DNA sequence or interact with a DNA-binding transcription factor. Acting as an indicator or marker to facilitate recognition by other molecules in the cell. Recognition of the tag, which can be covalently attached to the target molecule, may result in modification, sequestration, transport or degradation of the molecule in question. Modulates the activity of an enzyme. null
