Functional Description
 Cytoplasmic intermediate filaments provide mechanical strength to cells. Essential protein, involved in attachment structures in epidermal cells that connect muscles to the external cuticle. Required in morphogenesis and epidermal integrity. Probable component of embryonic epidermal attachment structures. Functions in larval muscle attachment independently of ifa-2.
