Research Excerpts

Overview

Involucrin is a precursor protein that is upregulated in psoriasis. It is a marker of keratinocyte differentiation that is expressed in the suprabasal epidermis and this expression requires AP1 factor interaction at the AP1-5 site.

Effects

Involucrin has been considered as a cornified envelope precursor protein expressed specifically in terminally differentiating keratinocytes and squamous epithelia. The involucrin gene has a single intron upstream of the translational start site, and removal of this intron did not affect tissue- or stratum-specific expression.

Involucrin mRNA levels increase 10-fold and promoter activity 5-11-fold when differentiation is induced by phorbol ester. Involucin plays an important role in the lipid and protein compound envelopes of mammalian epidermal corneocytes.
