35 kDa proteins are not components of vertebrate smooth muscle thin filaments.
A 35 kDa protein present in vertebrate smooth muscle and capable of binding to purified actin does not appear to be a constituent of smooth-muscle thin filaments in vivo; instead, it is more likely to be a component easily solubilized from particulate material which then spuriously interacts with actin.
