 y-tubulin | involved in nucleation of microtubule growth |
| microtubule organizing center | region in cell, such as a centrosome or basal body, from which microtubules grow. Microtubules are nucleated at their minus end, with their plus ends growing away from MTOC |
| y-tubulin ring complex | y-tubulin combines with several other associated proteins to form this structure. Acts as a scaffold for a/B tubulin dimers to begin polymerization. Acts a cap for the minus end while microtubule growth continues towards the plus direction |
| centrosome | centrally located organelle that is the primary MTOC and acts as the spindle pole during mitosis. microtubules nucleated at the centrosome continuously grow and shrink via dynamic instability. Composed of a centrosome matrix that contains over 50 y-TuRC |
| Centrioles | short cylindrical array of microtubules. Organize centrosome matrix |
| where are actin filaments often nucleated? | plasma membrane |
| Where do microtubules emanate from in animal cells? | centrosome |
| what nucleates microtubules? | Y-tubulin ring complex |
