small proline-rich protein 2E; SPR-2E; small proline-rich protein II; SPR-II (SPRR2E)

Function

• cross-linked envelope protein of keratinocytes
• keratinocyte protein that first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase; this results in the formation of an insoluble envelope beneath the plasma membrane

Structure

belongs to the cornifin (SPRR) family

Compartment

cytoplasm

Expression

• expressed during squamous differentiation of epidermal keratinocytes

More general terms
