Gene Gene information from NCBI Gene database.
Entrez ID 5318
Gene name Plakophilin 2
Gene symbol PKP2
Synonyms (NCBI Gene)
ARVD9
Chromosome 12
Chromosome location 12p11.21
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
