diacylgycerol (DAG) |
A second messenger produced by the cleaving of a certain kind of phospholipid in the plasma membrane. |
|
|
scaffolding proteins |
A type of large replay proteins to which several other relay proteins are simultaneously attached to increase the efficiency of signal transduction. |
|
|
adenylyl cyclase |
An enzyme that converts ATP to cyclic AMP in response to a chemical signal. |
|
|
inositol triphosphate (IP3) |
A second messenger that functions as an intermediate between certain non steroid hormones and a third messenger , a rise in cytoplasmic Ca2+ concentration. |
|
|
protein phosphatase |
An enzyme that removes phosphate groups from proteins, often functioning to reverse the effect of a protein kinase. |
|
|
Second messengers |
A small,nonprotein, water-soluble molecule or ion,such as calcium ion or cyclic AMP, that relays a signal to a cell's interior in response a signal received by a signal receptor protein. |
|
|
cyclic AMP or cAMP |
Cyclic adenosine monophosphate, a ring-shaped molecule made from ATP that is a common intercellular signaling molecule(second messenger) in eukaryotic cells (for example, in vertebrate endocrine cells). It is also a regulator of some bacterial operons. |
|
|
protein kinase |
An enzyme that transfers phosphate groups from ATP to a protein. |
