periplakin; 195 kD cornified envelope protein; 190 kD paraneoplastic pemphigus antigen (PPL, KIAA0568)
Function:
- component of the cornified envelope of keratinocytes
- may link the cornified envelope to desmosomes & intermediate filaments
- may act as a localization signal in PKB/AKT-mediated signaling
- homodimer or a heterodimer with envoplakin (EVPL)
- interacts with PPHLN1 & VIM
- binds to the PH domain of AKT1
- interacts with FCGR1A
Structure:
- belongs to the plakin or cytolinker family
- contains 2 plectin repeats
- contains 4 spectrin repeats
Compartment:
- cell junction, desmosome

- nucleus
- mitochondrion (putative)
- associated with desmosomes & intermediate filaments
Expression:
- expressed in stratified squamous epithelia & in some other epithelia
- expressed during differentiation of epidermal keratinocytes
