Function
- cross-linked envelope protein of keratinocytes
- keratinocyte protein that first appears in the cell cytosol
- ultimately becomes cross-linked to membrane proteins by transglutaminase
- process results in the formation of an insoluble envelope beneath the plasma membrane (putative)
Structure
belongs to the cornifin (SPRR) family
Compartment
Expression
- induced during squamous differentiation of epidermal keratinocytes (putative)
