General annotation (Comments)

Function

Vitronectin is a cell adhesion and spreading factor found in serum and tissues. Vitronectin interact with glycosaminoglycans and proteoglycans. Is recognized by certain members of the integrin family and serves as a cell-to-substrate adhesion molecule. Inhibitor of the membrane-damaging effect of the terminal cytolytic complement pathway.

Subunit structure

Interacts with SERPINE1/PAI1 and C1QBP By similarity. Monomer.

Subcellular location

Secretedextracellular space.

Tissue specificity

Plasma.

Domain

The SMB domain mediates interaction with SERPINE1/PAI1 By similarity.

Post-translational modification

Sulfated on 2 tyrosine residues By similarity.

N- and O-glycosylated. Ref.2

It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.

Sequence similarities

Contains 4 hemopexin repeats.

Contains 1 SMB (somatomedin-B) domain.
