Tubulins are a major component of ciliary microtubules and the principal protein subunit of microtubules in the cell cytoplasm.
They show how CaMKII kinase domains can collectively bind and phosphorylate 6-bit bytes, resulting in hexagonally-based patterns of phosphorylated tubulins in microtubules (Figure).
Both basic and clinical sciences are investigating the family of proteins called the tubulins, which form microtubules that are proving important in both disease mechanisms and therapies.
Tubulins are the proteins that form microtubules, which are key components of the cellular cytoskeleton (structural network).
Tubulins and the microtubules they form are obviously essential components of all eukaryotic cells.
The assembly by [alpha]/[beta] tubulin dimers is a process requiring nucleotide GTP (guanosine triphosphate) to bind to both [alpha] and [beta] tubulins.
Gant Luxton and Kevin Tyler (Northwestern University [NWU], Chicago, IL) demonstrated a rapid association of host tubulins with the plasma membrane at the site of Trypanosoma cruzi contact.
If they have truly identified the origin of eukaryotic tubulins, then it would be extremely important," says Jeffery Errington of Oxford University in England, who studies a bacterial protein with actinlike properties (SN: 3/31/01, p.

These data demonstrate that indibulin has distinct biologic and molecular properties from other tubulin binding agents and strongly suggest a very different toxicity profile, particularly with regard to peripheral neuropathy.
Results of the studies presented at the Prague meeting demonstrate that ENMD-1420 (previously CC-5079) inhibits tubulin polymerization and TNF-Alpha production and has both in vitro and in vivo antitumor activity.
March 24 /PRNewswire-FirstCall/ -- Celgene Corporation announced that it has signed a licensing agreement with EntreMed Corporation (ENMD) whereby EntreMed has been granted rights to the development and commercialization of Celgene's tubulin inhibitor compounds, a class of orally available, anti-proliferative compounds that have demonstrated, in preclinical models, activity against drug-resistant cancer cells, inhibition of inflammatory cytokines and anti-angiogenic activity.
