MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a component of desmosomes and of the epidermal cornified envelope in keratinocytes. The N-terminal domain of this protein interacts with the plasma membrane and its C-terminus interacts with intermediate filaments. Through its rod domain, this protein forms complexes with envoplakin. This protein may serve as a link between the cornified envelope and desmosomes as well as intermediate filaments. AKT1/PKB, a protein kinase mediating a variety of cell growth and survival signaling processes, is reported to interact with this protein, suggesting a possible role for this protein as a localization signal in AKT1-mediated signaling. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice are fertile and grossly normal with no apparent skin abnormalities. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a G to T transversion at position 5362 of the Ppl transcript in exon 22 of 22 total exons. The mutated nucleotide causes a serine to proline substitution at amino acid 1742 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Ppl gene encodes a 1755 amino acid component of the cornified envelope of keratinocytes known as periplakin. The protein may link the cornified envelope to desmosomes and intermediate filaments, and may act as a localization signal in PKB/AKT-mediated signaling. Periplakin contains three spectrin repeats at residues 214-315, 321-483 and 503-610, and two plectin repeats at residues 1650-1684 and 1699-1734 (Uniprot Q9R269). Homozygous null mice are fertile and grossly normal with no apparent skin abnormalities.

The S1742P change occurs after the second plectin repeat, and is predicted to be probably damaging by the PolyPhen program.
