Siganl Transduction Help

Post by LSUtiga21 » Mon Dec 07, 2009 4:15 pm

Any help with a question I have concerning a signal transduction property would be greatly appreciated -

In signal transduction, PIP2 is used in a wide variety of processes, even though it comprises a small percentage of all the phospholipids in the membrane. Why is it used so prominently?


Thank you so much in advance!!

because you can add phosphates to its head and remove them, creating binding sites for various proteins

PIP2 comprises such a small percentage of all the phospholipids in the membrane, because it is a signaling lipid and not a structural lipid for the membrane.
