Function

By connecting cytoskeletal elements to each other and to junctional complexes, the plakin family of cytolinkers plays a crucial role in orchestrating cellular development and maintaining tissue integrity.

Plakins are built from combinations of interacting domains that bind to microfilaments, microtubules, intermediate filaments, cell-adhesion molecules and members of the armadillo family.

Members

- desmoplakins
- periplakin (MIM.602871)
- plectin (MIM.601282)
- BPAG1 (MIM.113810)
- envoplakin (MIM.601590)

Pathology

Plakins are involved in both inherited and autoimmune diseases that affect the skin, neuronal tissue, and cardiac and skeletal muscle.
