Modulates leading keratinocyte migration and cellular adhesion to matrix proteins during a wound-healing response and promotes wound repair. May play a role during trichilemmal differentiation of the hair follicle (By similarity).
Subcellular locations: Apical cell membrane
Localized at the apical membrane of the most differentiated keratinocytes of the outer root sheath (ORS), clustered mainly in planar regions of the plasma membrane at the base of microvilli.
