Abstract All class I PI3K enzymes are obligate heterodimers, consisting of a catalytic subunit
tightly bound to a regulatory subunit. The regulatory subunit influences the subcellular
location, binding partners, and activity of the catalytic subunit. Regulatory subunits also
possess adaptor functions in cellular signaling, which are largely independent of their role in
regulating PI3K activity. This chapter reviews the structure and function of PI3K regulatory
subunits, focusing on the class IA subgroup.
