Switches

This ELM instance is part of the following 1 switching mechanism annotated at the switches.ELM resource:

SWTI000327:

An intramolecular interaction of the C-terminal PDZ binding motif of Amyloid beta A4 precursor protein-binding family A member 1 (APBA1) (also known as X11alpha/Mint1) with the PDZ domain tandem of APBA1 results in an auto-inhibited conformation of APBA1, where binding of ligands containing a PDZ binding motif such as Presenilin-1 (PSEN1) is blocked. Binding of these ligands might be regulated by phosphorylation of Y836 in the APBA1 PDZ-binding motif, as its mutation to glutamate releases autoinhibition and enhances the interaction of the APBA1 PDZ tandem with presenilin.
