Tubulin, gamma 1 is a protein in humans that is encoded by the TUBG1 gene. [5] This gene encodes a member of the tubulin superfamily. The encoded protein localizes to the centrosome where it binds to microtubules as part of a complex referred to as the gamma-tubulin ring complex. The protein mediates microtubule nucleation and is required for microtubule formation and progression of the cell cycle.
In cell biology, microtubule nucleation is the event that initiates de novo formation of microtubules (MTs). These filaments of the cytoskeleton typically form through polymerization of α- and β-tubulin dimers, the basic building blocks of the microtubule, which initially interact to nucleate a seed from which the filament elongates.
Tubulin alpha-4A chain is a protein that in humans is encoded by the TUBA4A gene.
Tubulin alpha-3C/D chain is a protein that in humans is encoded by the TUBA3C gene.
Targeting protein for Xklp2 is a protein that in humans is encoded by the TPX2 gene. It is one of the many spindle assembly factors that play a key role in inducing microtubule assembly and growth during M phase.
Ninein is a protein that in humans is encoded by the NIN gene. Ninein, together with its paralog Ninein-like protein is one of the proteins important for centrosomal function. This protein is important for positioning and anchoring the microtubules minus-ends in epithelial cells. Localization of this protein to the centrosome requires three leucine zippers in the central coiled-coil domain. Multiple alternatively spliced transcript variants that encode different isoforms have been reported.
Pericentrin (kendrin), also known as PCNT and pericentrin-B (PCNTB), is a protein which in humans is encoded by the PCNT gene on chromosome 21. This protein localizes to the centrosome and recruits proteins to the pericentriolar matrix (PCM) to ensure proper centrosome and mitotic spindle formation, and thus, uninterrupted cell cycle progression. This gene is implicated in many diseases and disorders, including congenital disorders such as microcephalic osteodysplastic primordial dwarfism type II (MOPDII) and Seckel syndrome.
Gamma-tubulin complex component 2 is a protein that in humans is encoded by the TUBGCP2 gene. It is part of the gamma tubulin complex, which required for microtubule nucleation at the centrosome.
Tubulin gamma-2 chain is a protein that in humans is encoded by the TUBG2 gene.
Gamma-tubulin complex component 3 is a protein that in humans is encoded by the TUBGCP3 gene. It is part of the gamma tubulin complex, which required for microtubule nucleation at the centrosome.
Gamma-tubulin complex component 5 is a protein that in humans is encoded by the TUBGCP5 gene. It is part of the gamma tubulin complex, which required for microtubule nucleation at the centrosome.
Gamma-tubulin complex component 6 is a protein that in humans is encoded by the TUBGCP6 gene. It is part of the gamma tubulin complex, which required for microtubule nucleation at the centrosome.
Neural precursor cell expressed, developmentally down-regulated 1, also known as Nedd1, is a human gene and encodes the protein NEDD1.
Centrosomal protein of 192 kDa, also known as Cep192, is a protein that in humans is encoded by the CEP192 gene. It is the homolog of the C. elegans and D. melanogaster gene SPD-2.
Centrosomal protein of 164 kDa, also known as CEP164, is a protein that in humans is encoded by the CEP164 gene. Its function appears two be twofold: CEP164 is required for primary cilium formation. Furthermore, it is an important component in the response to DNA damage by UV light.
Centrosomal protein of 76 kDa, also known as CEP76, is a protein that in humans is encoded by the CEP76 gene.
Centrosomal protein of 78 kDa, also known as Cep78, is a protein that in humans is encoded by the CEP78 gene.
Centrosomal protein of 152 kDa, also known as Cep152, is a protein that in humans is encoded by the CEP152 gene. It is the ortholog of the Drosophila melanogaster gene asterless (asl) and both are required for centriole duplication.
Tubulin, gamma complex associated protein 4 is a protein in humans that is encoded by the TUBGCP4 gene. It is part of the gamma tubulin complex, which required for microtubule nucleation at the centrosome.
Tubulin, epsilon 1 is a protein in humans that is encoded by the TUBE1 gene. This gene encodes a member of the tubulin superfamily. This protein localizes to the centriolar sub-distal appendages that are associated with the older of the two centrioles after centrosome duplication. This protein plays a central role in organization of the microtubules during centriole duplication
Sfi1 homolog, spindle assembly associated (yeast) is a protein that in humans is encoded by the SFI1 gene. It localizes to the centriole, and its S. pombe ortholog has been shown to be involved in spindle pole body duplication. SFI1 forms a complex with centrin 2.
