APBA2
Template:Short description Template:Infobox gene Amyloid beta A4 precursor protein-binding family A member 2 is a protein that in humans is encoded by the APBA2 gene.[1][2]
Structure
This protein has phosphotyrosine-binding domain (PTB domain or PID) in the middle and two PDZ domains at C-terminal.
Function
The protein encoded by this gene is a member of the X11 protein family. It is a neuronal adaptor protein that interacts with the Alzheimer's disease amyloid precursor protein (APP). It stabilises APP and inhibits production of proteolytic APP fragments including the A beta peptide that is deposited in the brains of Alzheimer's disease patients. This gene product is believed to be involved in signal transduction processes. It is also regarded as a putative vesicular trafficking protein in the brain that can form a complex with the potential to couple synaptic vesicle exocytosis to neuronal cell adhesion.[2]
Interactions
APBA2 has been shown to interact with CLSTN1,[3][4] RELA[5] and amyloid precursor protein.[3][6][7]
