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
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
short cylindrical array of microtubules. Organize centrosome matrix
