General annotation (Comments)

Function	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.
Subunit structure	Interacts with GCP2 and GCP3. Interacts with B9D2 By similarity. Interacts with CDK5RAP2; the interaction is leading to centrosomal localization of TUBG1 and CDK5RAP2. Interacts with PIFO/C1orf88. Ref.8 Ref.9
Subcellular location	Cytoplasm › cytoskeleton › centrosome Ref.7.
Post-translational modification	Phosphorylation at Ser-131 by BRSK1 regulates centrosome duplication, possibly by mediating relocation of gamma-tubulin and its associated proteins from the cytoplasm to the centrosome By similarity.
Sequence similarities	Belongs to the tubulin family.
Mass spectrometry	Molecular mass is 51197.98 Da from positions 1 - 451. Determined by MALDI. Ref.6
