Background Information

Involucrin is a protein precursor of the epidermal cornified envelope that is assembled in the outermost layers of the epidermis. Involucrin expression is restricted to the suprabasal epidermal layers (spinous and granular layers) during normal keratinocyte differentiation and is a useful marker of terminal differentiation. The predicted MW of involucrin is 68 kDa, but it also forms 120 kDa dimers, while different reports provided variable results ranging from 90-140 kDa. (PMID: 11099111, 1503502, 12150517)
