Involucrin Antibody

Involucrin is a protein component of human skin and in humans is encoded by the IVL gene. It is a highly reactive, soluble, transglutaminase substrate protein present in keratinocytes of epidermisand other stratified squamous epithelia. It first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase thus helping in the formation of an insoluble envelope beneath the plasma membrane functioning as a glutamyl donor during assembly of the cornified envelope. Additionally, Involucrin is synthesised in the stratum spinosum and cross linked in the stratum granulosum by the transglutaminase enzyme that makes it highly stable. Thus it provides structural support to the cell, thereby allowing the cell to resist invasion by micro-organisms.
