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

A mitotic cell cycle checkpoint which delays mitotic onset in response to perturbations that affect cell shape via the actin cytoskeleton, septin organization, small cell size, and/or the extent of membrane growth.

The aggregation, arrangement and bonding together of septins and associated proteins to form an organized structure resembling a ring at the cell cortex.

The process in which the bud portion of a cell that reproduces by budding irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.

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).

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 modulates the rate or extent of progression through the cell cycle.

The mitotic cell cycle transition by which a cell in G2 commits to M phase. The process begins when the kinase activity of M cyclin/CDK complex reaches a threshold high enough for the cell cycle to proceed. This is accomplished by activating a positive feedback loop that results in the accumulation of unphosphorylated and active M cyclin/CDK complex.

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

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

The process in which the bud portion of a cell that reproduces by budding irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.

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

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

The process in which a multicellular organism, a unicellular organism or a group of unicellular organisms grow in a threadlike, filamentous shape.

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 a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

The process in which a group of unicellular organisms grow in a threadlike, filamentous shape.

The chemical reactions and pathways resulting in the breakdown of a protein by individual cells.

A process in which a protein is transported to, or maintained in, a location within a septin ring.

A growth pattern exhibited by budding haploid cells under certain growth conditions, in which cells retain the typical axial budding pattern of haploids, but become elongated and fail to separate after division; during growth on a solid substrate, this results in penetration of cells into the agar medium. An example of this process is found in Saccharomyces cerevisiae.

Any process that modulates the frequency, rate, extent or direction of cell growth.

A pattern of cell growth that occurs in conditions of nitrogen limitation and abundant fermentable carbon source. Cells become elongated, switch to a unipolar budding pattern, remain physically attached to each other, and invade the growth substrate.

The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

The cell cycle transition where a cell leaves M phase and enters a new G1 phase. M phase is the part of the mitotic cell cycle during which mitosis and cytokinesis take place.

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 deprivation of glucose.

The increase in size or mass of an organism, occurring within the cells or tissues of the host organism. This may (but not necessarily) include a filamentous growth form, and also can include secretion of proteases and lipases to break down host tissue. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Any process that stops, prevents or reduces the frequency, rate or extent of filamentous growth of a population of unicellular organisms.

Any process that stops, prevents, or reduces the frequency, rate or extent of pseudohyphal growth.

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

A tight ring-shaped structure that forms in the division plane at the site of cytokinesis; composed of members of the conserved family of filament-forming proteins called septins as well as septin-associated proteins. This type of septin structure is observed at the bud neck of budding fungal cells, at the site of cell division in animal cells, at the junction between the mother cell and a pseudohyphal projection, and also within hyphae of filamentous fungi at sites where a septum will form.

The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence.

A ring-shaped structure that forms at the site of cytokinesis in the bud neck of a budding cell; composed of members of the conserved family of filament forming proteins called septins as well as septin-associated proteins. In S. cerevisiae, this structure forms at the time of bud emergence and the septins show a high rate of exchange.

A ring-shaped structure that forms at the site of cytokinesis in the bud neck of a budding cell; composed of members of the conserved family of filament forming proteins called septins as well as septin-associated proteins. In S. cerevisiae, this structure forms at the time of bud emergence and the septins show a high rate of exchange.

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

A tubular structure with flared ends, shaped like an hourglass and composed of highly ordered arrays of septin filaments, that forms at the bud neck of a dividing cell. In S. cerevisiae, this structure is located at the bud neck throughout most of the cell cycle and the septins are fixed within the structure, not exchanging with soluble septins. This septin structure acts as a scaffold for other proteins that function at the bud neck.

A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
