. "This domain is found at the N-terminus of proteins containingvon Willebrand factor type A (VWA, Pfam:PF00092) and Cache (Pfam:PF02743) domains. It has been found in vertebrates, Drosophila and C. elegans but has not yet been identified in other eukaryotes. It is probably involved in the function of some voltage-dependent calcium channel subunits [1]. " . "VWA_N" . "VWA N-terminal" . "Wuster A" . "Family" . . . . . . . . . . . . . .
