Identification of two intermediates during processing of profilaggrin to filaggrin in neonatal mouse epidermis

Abstract

A major event in the keratinization of epidermis is the production of the histidine-rich protein filaggrin (26,000 mol wt) from its high molecular weight (greater than 350,000) phosphorylated precursor (profilaggrin). We have identified two nonphosphorylated intermediates (60,000 and 90,000 mol wt) in NaSCN extracts of epidermis from C57/Bl6 mice by in vivo… (More)
