APBB2
Amyloid beta A4 precursor protein-binding family B member 2 is a protein that in humans is encoded by the APBB2 gene.
The protein encoded by this gene interacts with the cytoplasmic domains of amyloid beta precursor protein and amyloid beta precursor-like protein 2. This protein contains two phosphotyrosine binding domains, which are thought to function in signal transduction.
