Function

In association with DPP4 is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM (By similarity). May have a role in tissue remodeling during development and wound healing, and contribute to invasiveness in malignant cancers. {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Cell projection, lamellipodium membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Cell projection, invadopodium membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Note=Found in cell surface lamellipodia, invadopodia and on shed vesicles. Colocalized with DPP4 in invadopodia and lamellipodia of migratory activated endothelial cells in collagenous matrix. Colocalized with DPP4 on endothelial cells of capillary-like microvessels but not large vessels within invasive breast ductal carcinoma (By similarity). {ECO:0000250}.

Disease Associations

Tissue Specificity

Detected in fibroblasts, in placenta, uterus, embryos from day 7-19 and in newborn mice (P1).
