The process of introducing a phosphate group on to a protein.

The process of introducing a phosphate group on to a protein.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

The chemical reactions and pathways involving a cofactor, a substance that is required for the activity of an enzyme or other protein. Cofactors may be inorganic, such as the metal atoms zinc, iron, and copper in certain forms, or organic, in which case they are referred to as coenzymes. Cofactors may either be bound tightly to active sites or bind loosely with the substrate.

The process of introducing a phosphate group on to a protein.

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

Any process that modulates the frequency, rate or extent of gene expression such that an expression pattern recurs with a regularity of approximately 24 hours.

The phosphorylation by a protein of one or more of its own serine amino acid residues, or a serine residue on an identical protein.

The phosphorylation by a protein of one or more of its own serine amino acid residues, or a serine residue on an identical protein.

Any process that decreases cell volume.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, a hypotonic environment, i.e. an environment with a lower concentration of solutes than the organism or cell.

A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane.

A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane.

Any process that stops, prevents or reduces the frequency, rate or extent of chloride transport.

Any process that stops, prevents or reduces the frequency, rate or extent of chloride transport.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space.
