Abstract in another language

The highly abundant AAA-ATPase p97 is required for diverse cellular processes, of which ER-associated protein degradation (ERAD) is understood best. Previously, a new role of p97 in spindle disassembly at the end of mitosis has been reported. However, we show that neither addition of dominant-negative p97 mutants nor depletion of crucial p97 adaptors impairs transition of meiotic spindles into interphase arrays of microtubules. The dominant-negative approach is validated by inhibition of ERAD, which we reconstitute for the first time in the powerful biochemical system of Xenopus egg extracts. The role of p97 in spindle disassembly during meiotic exit should therefore be reconsidered.
