Cell cycle-dependent changes in microtubule dynamics in living cells expressing green fluorescent protein-alpha tubulin.

abstract：:m-AAA proteases are ATP-dependent proteolytic machines in the inner membrane of mitochondria which are crucial for the maintenance of mitochondrial activities. Conserved nuclear-encoded subunits, termed paraplegin, Afg3l1, and Afg3l2, form various isoenzymes differing in their subunit composition in mammalian mitochon...
