Template:STRUCTURE 2k6n Villin (VIL) is an actin-binding protein. The images on the left and right correspond to one representative villin structure, i.e. the human supervillin headpiece (2k6n). It contains gelsolin-like domains in its N-terminal and a helical headpiece which binds actin. ^[1] Supervillin (SVIL) contains numerous gelsolin-like domains in its C-terminal and interacts with actin. Advillin (AVIL) is another actin-binding protein in the gelsolin superfamily which is expressed in the peripheral sensory neurons.
