Pallain protein is a cytoskeletal protein coded by the palladin gene (KIAA0992). Palladin was characterised independently by two research groups, first in the lab of Carol Otey (in 2000) and then in the lab of Olli Carpén (in 2001). 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.
