AHNAK

Neuroblast differentiation-associated protein AHNAK, also known as desmoyokin, is a protein that in humans is encoded by the AHNAK gene.[5][6][7] AHNAK was originally identified in 1989 (in bovine muzzle epidermal cells) and named desmoyokin due to its localization pattern (that resembled a yoke) in the desmosomal plaque.[8] AHNAK has been shown to be essential for pseudopod protrusion and cell migration.
