PFAM accession number:PF08399
Interpro abstract (IPR013608):

This domain is found at the N terminus of proteins containing von Willebrand factor type A (VWA, IPR002035 ) and Cache ( IPR004010 ) domains. It has been found in vertebrates, Drosophila melanogaster (Fruit fly) and Caenorhabditis elegans but has not yet been identified in other eukaryotes. It is probably involved in the function of some voltage-dependent calcium channel subunits [ (PUBMED:11487633) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry VWA_N
