Gamma-tubulin complex component 2is aproteinthat in humans is encoded by theTUBGCP2gene. It is part of the gamma tubulin complex, which required formicrotubule nucleationat thecentrosome. Gamma-tubulin complex is necessary for microtubule nucleation at the centrosome. Gamma-tubulin complex is composed of gamma-tubulin, TUBGCP2, TUBGCP3, TUBGCP4, TUBGCP5 and TUBGCP6.
