Annexin A7/ANXA7 Protein, Human

Annexin A7 Protein, Human is a 51 kDa multifunctional protein which belongs to the the group A annexin family and contains an extraordinarily long amino terminus. Annexin A7 is a membrane binding protein with diverse properties including voltage sensitive calcium channel activity, ion selectivity and membrane fusion^[1][2].

The Annexins comprise a family of proteins that are involved in many aspects of cellular membrane dynamics and the regulation of membrane-associated proteins.
Annexin A7 is encoded by ANXA7 gene and is the first isolated annexin, mediating the Ca²⁺-regulated chromaffin granule exocytosis. Annexin 7 has molecular weight of approximately 51 kDa with a unique, highly hydrophobic N-terminal domain of 167 amino acids and a conserved C-terminal region of 299 amino acids. Annexin A7 plays an important role in membrane fusion during exocytosis, localizing predominantly in the cytoplasm and showing a high prevalence in the brain, heart, and skeletal muscle^[1].
