NYAP1 (Neuronal Tyrosine-Phosphorylated Adaptor for PI3K) encodes a neuronal phosphoprotein that functions as an adaptor protein linking tyrosine kinase signaling to phosphoinositide 3-kinase (PI3K) pathways. GWAS have identified NYAP1 as a susceptibility gene for late-onset Alzheimer's disease (LOAD).[1]
NYAP1 is a 380 amino acid protein that is highly expressed in neurons. It contains multiple protein-protein interaction domains and is tyrosine-phosphorylated in response to neuronal activity.[2]
Key normal functions include:
NYAP1 has been identified as a LOAD risk gene. The mechanism likely involves dysregulation of PI3K/Akt signaling, which is critical for neuronal survival and is impaired in AD.[1][4]
Potential Mechanisms:
Rare pathogenic variants in NYAP1 have been associated with intellectual disability and neurodevelopmental disorders.
NYAP1 expression pattern:
NYAP1 research utilizes several animal models:
NYAP1 expression can be assessed through:
