Activity summary

Adenylate kinase 1 also known as AK1 plays a critical role in cellular energy homeostasis. It catalyzes the reversible transfer of a phosphate group from ATP to AMP forming two ADP molecules. AK1 is a 24-kilodalton protein largely expressed in tissues with high-energy demands like brain heart and skeletal muscle. Expression levels vary but AK1's presence is notably higher in these energy-intense regions highlighting its importance in energy transfer and equilibrium.

Biological function summary

Adenylate kinase 1 is essential for maintaining the adenine nucleotide pool balance. It does not act alone but functions within diverse cellular contexts ensuring efficient energy supply which is necessary for critical cellular processes. In these contexts AK1 forms part of a larger network that involves other kinases and molecules operating to sustain sufficient energy levels during periods of high activity or stress. This orchestration of molecules ensures cells adapt to changing energy requirements swiftly.

Pathways

AK1 is a critical component of the ATP-generating phosphotransfer network and is involved in the cellular adenylate kinase reaction pathway. It interacts closely with proteins such as AMP-activated protein kinase (AMPK) which assists in detecting and responding to energy deficits. In the context of the phosphotransfer network maintaining the balance between ATP ADP and AMP is important and AK1 enables this dynamic equilibrium. By interrelating with these pathways AK1 supports efficient energy transduction and cellular adaptation to metabolic changes.

Associated diseases and disorders

Abnormal AK1 function or expression has been implicated in metabolic conditions like mitochondrial myopathy and heart diseases such as myocardial infarction. A disruption in the balance of adenylate kinase activity can lead to energy deficiency aggravating these conditions. Connections to these diseases involve proteins such as creatine kinase which plays a role in energy buffering. The interplay between AK1 and associated kinases is key in understanding how energetic imbalances contribute to the development and progression of these diseases.
