The process of removing one or more phosphoric residues from a protein.

Any process involved in the maintenance of an internal steady state of cations at the level of a cell.

Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.

The mitotic cell cycle transition by which a cell in G1 commits to S phase. The process begins with the build up of G1 cyclin-dependent kinase (G1 CDK), resulting in the activation of transcription of G1 cyclins. The process ends with the positive feedback of the G1 cyclins on the G1 CDK which commits the cell to S phase, in which DNA replication is initiated.

Any process involved in the maintenance of an internal steady state of ions at the level of a cell.

Any process involved in the maintenance of an internal steady state of ions at the level of a cell.

Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell.

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 addition of a lipoyl group to an amino acid residue in a protein.

Any process involved in the maintenance of an internal steady state of cations at the level of a cell.

Any process that decreases the rate or frequency of conjugation with cellular fusion.

Any process that decreases the rate or frequency of conjugation with cellular fusion.

The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.

Any process involving pheromones that stops, prevents or reduces the rate of transcription from an RNA polymerase II promoter.

Any process involving pheromones that stops, prevents or reduces the rate of transcription from an RNA polymerase II promoter.

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 cation stress, an increase or decrease in the concentration of positively charged ions in the environment.

Any process that modulates the frequency, rate or extent of iron-sulfur cluster assembly.

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

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.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.
