[3][4][5] This gene encodes a cytosolic protein that binds to the signaling molecule, neuronal nitric oxide synthase (nNOS).

This protein has a C-terminal PDZ-binding domain that mediates interactions with nNOS and an N-terminal phosphotyrosine binding (PTB) domain that binds to the small monomeric G protein, Dexras1.

[5] NOS1AP polymorphisms has been associated with the QT interval length.
