¼±ÇóMicrotubule formation in vitro in solutions containing low calcium concentrations. ×÷Õß: Weisenberg, R C À´Ô´³ö°æÎï: Science ¾í: 177 ÆÚ: 54 Ò³: 1104-5 ³ö°æÄê: 1972 Sep 22 ÕªÒª: Isolated rat brain tubulin can be repolymerized in vitro in solutions containing adenosine triphosphate or guanosine triphosphate, magnesium ions, and a good calcium chelator. The extreme sensitivity of tubulin to calcium ions explains the failure of previous efforts to obtain polymerization and suggests a possible mechanism for regulation of microtubule polymerization in vivo.
