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

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

The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

Any process that activates or increases the frequency, rate or extent of exocytosis.

Any process that activates or increases the frequency, rate or extent of exocytosis.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

Any process that activates or increases the frequency, rate or extent of the IRE1-mediated unfolded protein response.

The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the plasma membrane.

The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

Any cellular process that results in the specification, formation or maintenance of polarized actin-based cytoskeletal structures.

The process in which a cell switches from monopolar cell growth to bipolar cell growth.

Any cellular process that results in the specification, formation or maintenance of a polarized intracellular organization or cell growth patterns that regulate the shape of a cell.

Any cytokinesis, site selection that is involved in mitotic cell cycle.

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

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

The end of a cellular bud distal to the site of attachment to the mother cell.

The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding.

The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.

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.

A sterol-rich region of the plasma membrane which forms at the cell surface overlying the contractile ring and spreads into the invaginating plasma membrane surrounding the septum.

A cell tip at which no growth takes place. For example, in fission yeast the cell end newly formed by cell division does not grow immediately upon its formation, and lacks actin cytoskeletal structures.

A cell tip that was newly formed at the last cell division, and that has started to grow after the cell has activated bipolar cell growth (i.e. in which new end take-off, NETO, has taken place). New end take-off is when monopolar cells initiate bipolar growth.

A cell tip which has existed for at least one complete cell cycle, and at which polarized growth occurs, which is part of a cell that has activated bipolar cell growth (i.e. in which new end take-off, NETO, has taken place). For example, in fission yeast the cell end that existed prior to cell division grows immediately after division, and contains a distinctive complement of proteins including actin cytoskeletal structures.

The region at the end of the longest axis of a cylindrical or elongated cell.

The component of the plasma membrane surrounding the cell tip consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the plasma membrane surrounding the cell tip or some other covalently attached group such as a GPI anchor that is similarly embedded in the plasma membrane surrounding the cell tip.
