Model confidence (pLDDT)

The mean pLDDT of this model is 92.2 (very high overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

Required for the recruitment and the assembly of the gamma-tubulin ring complex (gTuRC) at the centrosome (PubMed:20360068, PubMed:38609661, PubMed:39321809). The gTuRC regulates the minus-end nucleation of alpha-beta tubulin heterodimers that grow into microtubule protafilaments, a critical step in centrosome duplication and spindle formation (PubMed:38609661, PubMed:39321809)

Subunit structure

Associates with the gamma-tubulin ring complex (gTuRC) consisting of TUBGCP2, TUBGCP3, TUBGCP4, TUBGCP5 and TUBGCP6 and gamma-tubulin TUBG1 or TUBG2; within the complex, interacts with TUBGCP3 and TUBGCP6 to form a luminal bridge with actin that stabilizes the initial structure during complex assembly (PubMed:38609661, PubMed:39321809). Interacts with TUBG1 (PubMed:20360068)

Subcellular location
