The protein encoded by this gene may modulate the activity and localization of nitric oxide synthase (endothelial and neuronal) and thus nitric oxide production. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Aug 2012]
Function:
NOSIP is a novel type of modulator that promotes translocation of eNOS from the plasma membrane to intracellular sites, thereby uncoupling eNOS from plasma membrane caveolae and inhibiting NO synthesis.
Subunit:
Interacts with NOS1 and NOS3.
Subcellular Location:
Cytoplasm. Nucleus. Note: Translocates from nucleus to cytoplasm in the G2 phase of the cell cycle.
Tissue Specificity:
Expressed in heart, brain and lung. Present in endothelial cells (at protein level).
Similarity:
Belongs to the NOSIP family.
