Protein Structure

UniProt Annotation

Function

Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism. Adenylate kinase activity is critical for regulation of the phosphate utilization and the AMP de novo biosynthesis pathways. Plays a key role in hematopoiesis. {ECO:0000255HAMAP- Rule:MF_03168}.

Subcellular Localization

Mitochondrion intermembrane space {ECO:0000255HAMAP-Rule:MF_03168}.

Disease Associations

Tissue Specificity

Present in the inner ear. Not detected in the vestibule at any developmental stage. Present at high level in the cochlea uniquely in the stria vascularis at postnatal day 7 but not at birth. Present within the lumen of the stria vascularis capillaries. Not detected in the capillaries or vessels of the adjacent connective tissue (at protein level). {ECO:0000269PubMed:19043416}.
