MTSpindownsfromExtracts
MT Spindowns from ExtractsArshad DesaiNotes:The key variable in MT spindown experiments is ATP. Under high ATP conditions,conventional MAPs are selectively co-sedimented with microtubules. In theabsence of ATP (or in presence of AMPPNP which induces rigor binding of motorsto MTs), both motors and MAPs will bind to MTs and pellet with themicrotubules. For MAP and motor analysis, I often supplement the extract with exo......阅读全文
