Switch #:
SWTI000220
Switch type:
Binary
Switch subtype:
Allostery

Description:
Phosphorylation of cAMP-dependent protein kinase catalytic subunit alpha (PRKACA) at S11 shifts the conformational equilibrium to the myristoyl-out conformation, making the myristoyl moiety available for interaction with the membrane.

Participants:
(1) cAMP-dependent protein kinase catalytic subunit alpha (PRKACA)
(2) membrane

Interactions
Interaction #1 PRKACA - membrane

Interfaces
(1) MOD_NMyristoyl motif (1MGNAAAA7) in cAMP-dependent protein kinase catalytic subunit alpha (PRKACA)
(2) membrane

Interaction Regulation
PTM-dependent Induction (Phosphorylation of S11 on cAMP-dependent protein kinase catalytic subunit alpha (PRKACA)) of the cAMP-dependent protein kinase catalytic subunit alpha (PRKACA) MOD_NMyristoyl motif - membrane interaction

Additional Information
Structural information: 1CMK
