Any process that modulates the frequency, rate or extent of tetrapyrrole catabolic process.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a silver ion stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a metal ion stimulus.

OBSOLETE. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipoic acid stimulus.

The process in which a relatively unspecialized cell acquires specialized features of a stem cell. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.

Protein complex formed by an RNA binding protein Red1, an RNA helicase Mtl1, Red5, Rmn1, Iss10/Pir1, and Ars2/Pir2. This complex is required for the recruitment of the nuclear exosome to Mmi1 nuclear focus. It is likely related to the human CBCN complex. This complex is also known as RNA silencing (NURS) complex.

The process whose specific outcome is the progression of the stem cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to its specific fate.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an ultrasonic stimulus.

The series of molecular signals initiated by the binding of a leukemia inhibitory factor to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.

The series of molecular signals initiated by an extracellular ligand binding to a receptor on the surface of the target cell, where the receptor possesses catalytic activity or is closely associated with an enzyme such as a protein kinase, and ending with the regulation of a downstream cellular process, e.g. transcription.

A synaptic vesicle belonging to the pool that repopulate vacancies within the readily releasable pool (RRP) of synaptic vesicles, and require more significant stimuli than the RRP in order to release neurotransmitter; about 10-15% of the total number of synaptic vesicles at a resting terminal bouton are in this state.

A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.

A synaptic vesicle belonging to the pool that remain unreleased even after prolonged stimulation causes a saturating degree of vesicular turnover. 50-80% of the total number of synaptic vesicles at a resting terminal bouton are in this pool.

The process in which a cell becomes capable of differentiating autonomously into a stem cell regardless of its environment; upon determination, the cell fate cannot be reversed.

A process involved in cell fate commitment. Once determination has taken place, a cell becomes committed to differentiate down a particular pathway regardless of its environment.

Binding to a ciliary targeting sequence, a specific peptide sequence that acts as a signal to localize a membrane protein to the ciliary membrane.

The process whose specific outcome is the progression of a pollen tube over time, from its initial formation to a mature structure.

A synaptic vesicle belonging to the pool of vesicles that are the first to be released as a result of chemical or electrical stimulation e.g. by an action potential, have the highest presynaptic membrane fusion probability and correspond to about 1% of the total number of synaptic vesicles at a resting terminal bouton.

The process in which the developmental fate of a cell becomes restricted such that it will develop into a stem cell.
