Protein
Small proline-rich protein 2D
Function
Cross-linked envelope protein of keratinocytes. It is a keratinocyte protein that first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase. All that results in the formation of an insoluble envelope beneath the plasma membrane.
Similarity
Belongs to the cornifin (SPRR) family.
