Thus, the mutation in K10 might cause irregularly shaped pathognomonic keratin intermediate filament (KIF) clumps in suprabasal keratinocytes which disrupt the structural stability in the suprabasal keratinocytes and also increase cyclin D, cyclin E, and phosho-Akt levels, all of which drive to hyperproliferation of keratinocytes in psoriasis. The gene discussed is KRT10; the disease is psoriasis.
