Summary: Predicted to enable several functions, including alpha-catenin binding activity; intermediate filament binding activity; and protein kinase C binding activity. Involved in several processes, including cardiac muscle cell action potential; cell-cell junction organization; and regulation of bicellular tight junction assembly. Located in adherens junction; desmosome; and intercalated disc. Human ortholog(s) of this gene implicated in arrhythmogenic right ventricular cardiomyopathy and arrhythmogenic right ventricular dysplasia 9. Orthologous to human PKP2 (plakophilin 2).

Plakophilin-2 loss promotes TGF-beta1/p38 MAPK-dependent fibrotic gene expression in cardiomyocytes.
Title: Plakophilin-2 loss promotes TGF-β1/p38 MAPK-dependent fibrotic gene expression in cardiomyocytes.
Plakophilin-2 silencing in epicardial cultures showed increased velocity of migration, increased proliferative rate, and increased adiposis.
Title: Plakophilin-2 and the migration, differentiation and transformation of cells derived from the epicardium of neonatal rat hearts.
demonstrated that loss of AnkG expression caused significant changes in subcellular distribution and/or abundance of PKP2 and Connexin43 as well as a decrease in intercellular adhesion strength and electric coupling
Title: Interactions between ankyrin-G, Plakophilin-2, and Connexin43 at the cardiac intercalated disc.
PKP2 associates with Na(V)1.5, and that knockdown of PKP2 expression alters the properties of the sodium current, and the velocity of action potential propagation in cultured cardiomyocytes.
Title: Loss of plakophilin-2 expression leads to decreased sodium current and slower conduction velocity in cultured cardiac myocytes.
Cx43 and PKP2 form a protein complex within the desmosome-like junction to regulate cell adhesion at the blood-testis barrier, partly through its effects on the occludin/ZO-1 complex, so as to facilitate the transit of primary preleptotene spermatocytes.
Title: Connexin 43 and plakophilin-2 as a protein complex that regulates blood-testis barrier dynamics.
Presence of plakophilin (PKP)2, a component of the desmosome, is essential for the proper function and distribution of gap junction protein connexin (Cx)43.
Title: Connexin43 remodeling caused by inhibition of plakophilin-2 expression in cardiac cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
