Palladin is a protein that in humans is encoded by the PALLD gene. Palladin is a component of actin-containing microfilaments that control cell shape, adhesion, and contraction. It is a part of the myotilin-myopalladin-palladin family and may play an important role in modulating the actin cytoskeleton. Palladin, in contrast to myotilin and myopalladin, which are expressed only in striated muscle, is expressed ubiquitously in cells of mesenchymal origin. Palladin's precise biological role is poorly understood, but it has been shown to play a role in cytoskeletal organization, embryonic development, cell motility, scar formation in the skin, and nerve cell development.
