CC -!- FUNCTION: Negatively regulates Golgi-to-plasma membrane trafficking by
CC interacting with PI4KB and inhibiting its activity. May play a role in
CC the physiology of neurons and is potentially important in memory and
CC learning. {ECO:0000250|UniProtKB:Q06BI3}.
CC -!- SUBUNIT: Interacts with PI4KB. This binding competes with FREQ/NCS1
CC binding in a calcium-dependent manner. {ECO:0000250|UniProtKB:Q06BI3}.
