Periphilin-1 is a protein that in humans is encoded by the PPHLN1 gene. [5]
The protein encoded by this gene is one of the several proteins that become sequentially incorporated into the cornified cell envelope during the terminal differentiation of keratinocyte at the outer layers of epidermis.
This protein interacts with periplakin, which is known as a precursor of the cornified cell envelope. The cellular localization pattern and insolubility of this protein suggest that it may play a role in epithelial differentiation and contribute to epidermal integrity and barrier formation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [5]
Keratin, type I cytoskeletal 4 also known as cytokeratin-4 (CK-4) or keratin-4 (K4) is a protein that in humans is encoded by the KRT4 gene.
Keratin 16 is a protein that in humans is encoded by the KRT16 gene.
Protein-glutamine gamma-glutamyltransferase K is a transglutaminase enzyme that in humans is encoded by the TGM1 gene.
Involucrin is a protein component of human skin and in humans is encoded by the IVL gene. In binding the protein loricrin, involucrin contributes to the formation of a cell envelope that protects corneocytes in the skin.
