Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains.

Integrin beta epidermal growth factor like domain 1; This is the I-EGF 1 domain found in several integrin betas such as integrin beta 1-7. Structural analysis reveal an epidermal growth factor-like (I-EGF) domains 1 and 2. EGF1 lacks one disulfide (C2-C4) relative to the integrin EGF 2, 3, and 4 domains, this allows the C-terminal end of EGF1 to flex remarkably relative to its N-terminal end.

Integrin beta subunits (N-terminal portion of extracellular region); Portion of beta integrins that lies N-terminal to their EGF-like repeats. Integrins are cell adhesion molecules that mediate cell-extracellular matrix and cell-cell interactions. They contain both alpha and beta subunits. Beta integrins are proposed to have a von Willebrand factor type-A "insert" or "I" -like domain (although this remains to be confirmed).

of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
