A regulatory process that halts progression through the cell cycle during one of the normal phases (G1, S, G2, M).

Any process that increases the frequency, rate or extent of peptidyl-threonine phosphorylation. Peptidyl-threonine phosphorylation is the phosphorylation of peptidyl-threonine to form peptidyl-O-phospho-L-threonine.

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

A process in which the transfer of one or more phosphate groups to a substrate transmits a signal to the phosphorylated substrate.

The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.

The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil.

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.

Any process that increases the rate, frequency, or extent of protein serine/threonine kinase activity.

Any process that stops, prevents or reduces the frequency, rate or extent of potassium ion transmembrane transporter activity.

Any process that stops, prevents or reduces the frequency, rate or extent of potassium ion transmembrane transport.

Any process that increases the frequency, rate or extent of peptidyl-threonine phosphorylation. Peptidyl-threonine phosphorylation is the phosphorylation of peptidyl-threonine to form peptidyl-O-phospho-L-threonine.

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

A process in which the transfer of one or more phosphate groups to a substrate transmits a signal to the phosphorylated substrate.

Any process that initiates the activity of an inactive protein kinase.

The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers that are not all identical. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

The process resulting in the physical partitioning and separation of a neuroblast into two daughter cells with different developmental potentials.

The process resulting in the physical partitioning and separation of a neuroblast into two daughter cells with different developmental potentials.

Any process that increases the rate, frequency, or extent of protein serine/threonine kinase activity.

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

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The volume enclosed by the membrane of a secretory granule.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

A protein complex which is capable of protein serine/threonine kinase activity.

Any membrane-enclosed lumen that is part of a ficolin-1-rich granule.

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.

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

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
