'Cap 90', a 90-kDa Ca2+-dependent F-actin-capping protein from vertebrate brain.
A Ca2+-dependent actin filament-capping protein of 90 kDa was purified from bovine brain using a new and rapid isolation procedure. This basically includes affinity purification on DNase-I agarose. The protein caps the fast-growing end of actin filaments but has no fragmenting or severing activity. Using Triton X-100-extracted cytoskeletons, capping and severing activities of actin-binding proteins become clearly distinguishable from each other.
