For every phosphate group added, there are specific lipid kinases — and phosphatases to remove it.
Phospholipid subcellular localization and dynamics
Additionally, phospholipases can cleave off the inositol head group and generate poly-phosphoinositols, which act as soluble signals in the cytosol. Volume I untangles the web of these enzymes and their products, and relates them to function in health and disease. Phosphoinositide 3-kinases and 3-phosphatases have received a special focus in volume I, and recent therapeutic developments in human disease are presented along with a historical perspective illustrating the impressive progress in the field.

Subcellular Biochemistry Free Preview. In depth discussion of the state of the art of phosphoinositide research Experts in the field discussing the 'hot' topics in phosphoinositide research A volume dedicated to the enzymes involved in the synthesis and degradation of phosphoinositides see more benefits. Changes in the balance between receptor retrieval from and delivery to the plasma membrane effectively modulate the strength and duration of a cell's response to a given extracellular stimulus. However, some receptors resume signalling after their internalization and, in these cases, the final output of the signalling process might differ notably from that elicited at the plasma membrane.
In the past few years, the role of PIs in cellular signalling and trafficking processes has been firmly established. Although the idea that PIs are localized to distinct subdomains or pools within the same compartment is attractive, at this point it seems difficult to prove experimentally. How enzyme functions are coordinated to avoid a waste of energy remains an open question. We apologize to all those whose studies could not be cited due to space limitations.
