CC -!- FUNCTION: Cross-linked envelope protein of keratinocytes. It is a
CC keratinocyte protein that first appears in the cell cytosol, but
CC ultimately becomes cross-linked to membrane proteins by
CC transglutaminase. All that results in the formation of an insoluble
CC envelope beneath the plasma membrane (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Not expressed in uterus.
CC {ECO:0000269|PubMed:15232223}.
CC -!- SIMILARITY: Belongs to the cornifin (SPRR) family. {ECO:0000305}.
