About PKP3

Cytogenetic location: 11p15.5 Genomic coordinates (GRCh38): 11:392,596-404,908 (from NCBI)

This gene has 11 transcripts (splice variants), 265 orthologues and 6 paralogues. Biased expression in skin (RPKM 51.4), esophagus (RPKM 46.7) and 11 other tissues.

Summary

This gene encodes a member of the arm-repeat (armadillo) and plakophilin gene families. Plakophilin proteins contain numerous armadillo repeats, localize to cell desmosomes and nuclei, and participate in linking Cadherins to intermediate filaments in the Cytoskeleton. This protein may act in cellular desmosome-dependent adhesion and signaling pathways. Two transcript variants encoding different isoforms have been found for this gene.
