NOS1AP

Nitric oxide synthase 1 adaptor protein (NOS1AP) also known as carboxyl-terminal PDZ ligand of neuronal nitric oxide synthase protein (CAPON) is a protein that in humans is encoded by the NOS1AP gene.[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. Studies of the related mouse and rat proteins have shown that this protein functions as an adapter protein linking nNOS to specific targets, such as Dexras1 and the synapsins.[5] NOS1AP polymorphisms has been associated with the QT interval length.[6]

Interactions

NOS1AP has been shown to interact with:

• LRP1,[7]
• LRP2,[7]
• NOS1,[4]
• RASD1,[8]
• SYN1[9]
