Class II PI 3-kinases

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Class II PI 3-kinases are a subgroup of the enzyme family, phosphoinositide 3-kinase that share a common protein domain structure, substrate specificity and method of activation.

Class II PI 3-kinases were the most recently identified class of PI 3-kinases and little is currently known about these enzymes.

There are three class II PI 3-kinase isoforms expressed in mammalian cells;
