Annexin A7 (ANXA7) Antibody

Background

ANXA7 is a calcium- and GTP-dependent membrane-binding protein that plays a key role in exocytosis, membrane repair, and cell signaling. It acts as a calcium sensor, facilitating the fusion of vesicles with the plasma membrane, particularly in processes such as neurotransmitter release and hormone secretion. ANXA7 is expressed in the brain, heart, and other tissues, where it contributes to cellular calcium homeostasis and cell survival mechanisms. Mutations or dysregulation of ANXA7 have been associated with neurodegenerative diseases, such as Parkinson's disease, and cancers, where it can act as a tumor suppressor by regulating cell proliferation and apoptosis. Its roles in membrane dynamics and calcium-dependent signaling underscore its importance in cellular communication and homeostasis.
