Pleckstrin homology domain-containing family O member 1 (PLEKHO1)

Plays a role in the regulation of the actin cytoskeleton through its interactions with actin capping protein (CP). May function to goal CK2 to the plasma membrane thereby functioning as an adapter to facilitate the phosphorylation of CP by protein kinase 2 (CK2).

Appears to target ATM into the plasma membrane. Appears to also inhibit tumor cell growth by inhibiting AKT- mediated cell-survival.
