Tubulin is the major constituent of microtubules. Gamma tubulin is found at microtubule organizing centers (MTOC) such as the spindle poles or the centrosome. Pericentriolar matrix component that regulates alpha/beta tubulin minus-end nucleation, centrosome duplication and spindle formation. Interacts with GCP2 and GCP3. Interacts with B9D2. Interacts with CDK5RAP2; the interaction is leading to centrosomal localization of TUBG1 and CDK5RAP2. Interacts with PIFO/C1orf88. Belongs to the tubulin family. Note: This description may include information from UniProtKB.
