Biological function summary
Nucleoside diphosphate kinase activity of NME4 contributes to energy homeostasis in cells. It assists in the generation of nucleoside triphosphates necessary for mitochondrial function and integrity. NME4 operates as part of multimeric complexes within the mitochondria ensuring efficient energy metabolism. Its role extends to contributing to cellular signaling pathways by providing the necessary energy substrates for a variety of cellular responses and activities.
Pathways
Researchers have found that NME4 is involved in the regulation of the mitochondrial apoptotic pathway. It interacts with other proteins involved in apoptosis such as Bcl-2 family members by influencing the mitochondrial outer membrane permeability. Additionally NME4 participates in pathways related to oxidative phosphorylation working alongside other proteins like ATP synthase to optimize energy production and utilization. These interactions underpin its versatility in sustaining cellular energy requirements and influencing cell survival.

기능
Mitochondria-specific nucleoside diphosphate kinase that catalyzes the transfer of a gamma-phosphoryl group from ATP to a nucleoside diphosphate via a ping-pong mechanism involving a phosphohistidine intermediate, participating in nucleoside triphosphate homeostasis (PubMed : 10799505, PubMed : 16313181, PubMed : 18635542, PubMed : 23150663). In vitro, purine nucleoside triphosphates are much more effective as donors and acceptors than pyrimidine nucleoside triphosphates, and ribonucleosides derivatives are superior to their deoxyribonucleosides counterparts (By similarity). Associates with cardiolipin-containing mitochondrial inner membrane and locally produces ADP in the mitochondrial intermembrane space, which is directly taken up via the ADP/ATP translocase (ANT) into the matrix to stimulate respiratory ATP regeneration (PubMed : 18635542, PubMed : 24970086). Also directly provides GTP for mitochondrial GTPases, such as the dynamin-related GTPase OPA1 (PubMed : 24970086). Additionally, catalyzes the anionic phospholipid transfer, namely cardiolipin, from the mitochondrial inner membrane (IM) to the outer membrane (OM) through the formation of contact sites between IM and OM, in a nucleoside diphosphate kinase-independent manner (PubMed : 17028143, PubMed : 23150663). The switch between the nucleoside diphosphate kinase and the phospholipid transfer activity may depend on the availability and accessibility of cardiolipin and other anionic phospholipids in the IM outer leaflet and OM inner leaflet (PubMed : 23150663).
