Filaggrin

Protein found in Homo sapiens

Filaggrin is a filament-associated protein that binds to keratin fibers in epithelial cells. Ten to twelve filaggrin units are post-translationally hydrolyzed from a large profilaggrin precursor protein during terminal differentiation of epidermal cells. In humans, profilaggrin is encoded by the FLG gene, which is part of the S100 fused-type protein (SFTP) family within the epidermal differentiation complex on chromosome 1q21. In cetaceans and sirenians, the FLG family has lost its function, with the curious exception of manatees in the latter clade: manatees still retain some functional FLG genes.
