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.

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

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

The lipoylation of peptidyl-lysine to form peptidyl-N6-lipoyl-L-lysine.

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.

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

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

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

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

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.

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