Summary
Predicted to enable DNA binding activity; cadherin binding activity; and lamin binding activity. Involved in several processes, including ameloblast differentiation; desmosome organization; and positive regulation of keratinocyte differentiation. Located in several cellular components, including desmosome; nucleus; and plasma membrane. Is active in cornified envelope. Is expressed in several structures, including alimentary system; respiratory system; sensory organ; skin; and urinary system. Human ortholog(s) of this gene implicated in ectodermal dysplasia. Orthologous to human PKP1 (plakophilin 1). [provided by Alliance of Genome Resources, Jul 2025]

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.
