Structural determinants of microtubule minus end preference in CAMSAP CKK domains

Structural determinants of microtubule minus end preference in CAMSAP CKK domains

CKK domain containing CAMSAP/Patronins recognise and regulate microtubule (MT) minus end dynamics. Here the authors compare cryo-EM structures of MT-bound human CKK and Naegleria gruberi CKK which lacks minus-end binding preference, finding NgCKK has a different interaction with, and inability to re...

Descripción
Sumario:CKK domain containing CAMSAP/Patronins recognise and regulate microtubule (MT) minus end dynamics. Here the authors compare cryo-EM structures of MT-bound human CKK and Naegleria gruberi CKK which lacks minus-end binding preference, finding NgCKK has a different interaction with, and inability to remodel, its MT binding site, shedding light on the CAMSAP/Patronin end binding mechanism.
