Protein inhibitor of neuronal nitric oxide synthase

摘要

An nNOS associated protein designated PIN-1 (Protein Inhibitor of nNOS) has been identified. It physically interacts with nNOS and inhibits its activity. Multiple lines of evidence indicate that PIN-1 is a regulator of nNOS: it is physiologically associated with nNOS, and it inhibits its catalytic activity. The extraordinary evolutionary conservation of PIN-1 and preliminary evidence that it interacts with multiple proteins, suggests that it may be a major biological regulatory protein influencing numerous physiological processes.
