nitric oxide synthase 1 (neuronal) adaptor protein

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. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2009]

Nitric Oxide Synthase 1 Adaptor Protein; C-Terminal PDZ Ligand Of Neuronal Nitric Oxide Synthase Protein; Nitric Oxide Synthase 1 (Neuronal) Adaptor Protein; CAPON; Ligand Of Neuronal Nitric Oxide Synthase With Carboxyl-Terminal PDZ Domain; C-Terminal PDZ Domain Ligand Of Neuronal Nitric Oxide Synthase (CAPON);

Adapter protein involved in neuronal nitric-oxide (NO) synthesis regulation via its association with nNOS/NOS1. The complex formed with NOS1 and synapsins is necessary for specific NO and synapsin functions at a presynaptic level. Mediates an indirect interaction between NOS1 and RASD1 leading to enhance the ability of NOS1 to activate RASD1. Competes with DLG4 for interaction with NOS1, possibly affecting NOS1 activity by regulating the interaction between NOS1 and DLG4 (By similarity).
In kidney podocytes, plays a role in podosomes and filopodia formation through CDC42 activation (PubMed:33523862).

Nephrotic syndrome 22 (NPHS22):
A form of nephrotic syndrome, a renal disease clinically characterized by severe proteinuria, resulting in complications such as hypoalbuminemia, hyperlipidemia and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. Some affected individuals have an inherited steroid-resistant form that progresses to end-stage renal failure. NPHS22 is an autosomal recessive, steroid-resistant form characterized by onset of progressive kidney dysfunction in infancy.
