Background: PIK3R4

PIK3R4 (phosphoinositide 3-kinase regulatory subunit 4) is a 150 kDa, 1358 amino acid (aa) adaptor protein that enhances the lipid kinase activity of PIK3 complexes and may be involved in regulating membrane trafficking late in the endocytic pathway. It is a regulatory subunit of the PI3K complex and is ubiquitously expressed. Within aa 58‑230, human PIK3R4 shares 99% aa identity with mouse and rat PIK3R4.
