Tubulin and microtubule structure Our knowledge of microtubule structure and its relationship to microtubule function continue to grow. Cryo-electron microscopy has given us new images of the microtubule polymerization and depolymerization processes and of the interaction of these polymers with motor proteins. We now know more about Tubulin in molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily. α- and β-tubulins polymerize into microtubules, a major component of the eukaryotic cytoskeleton. Microtubules function in many essential cellular processes, including mitosis. Tubulin-binding drugs kill cancerous cells by inhibiting microtubule dynamics, which are required for DNA segregation and therefore cell division. In eukaryotes.

Structure of tubulin: Tubulin is the major building block of microtubules which is an intracellular cylindrical filamentous structure present in almost all eukaryotic cells. Alpha and beta-tubulin.. Microtubule Structure Microtubules are hollow cylinders made up of repeating protein structures, specifically dimers of alpha and beta tubulin (also referred to in writing as ɑ-tubulin and β-tubulin). Dimers are complexes of two proteins Chemically, they are composed of two kinds of protein subunits: α-tubulin (tubulin A) and β-tubulin (tubulin B), each of M.W. 55,000 daltons. The wall of a microtubule is made up of a helical array of repeating α and β tubulin subunits. Assembly studies have indicated that the structural unit is an αβ dimer of 8 nm length

The structure of vinblastine bound to the tubulin-colchicine:RB3-SLD complex ((Tc) 2 R) was determined at 4.1 Å resolution. In (Tc) 2 R there is one vinblastine-binding site at the interface. While most of tubulin modifications reside in the flexible C-terminal tail of tubulin, acetylation of α-tubulin on K40 is localized to the inside of the microtubule, within the so-called αK40 loop. Using high-resolution cryo-EM maps of acetylated and deacetylated microtubules, in conjunction with molecular-dynamics methods, we found that acetylation restricts the range of motion of the αK40 loop

This sequence/structure analysis has led us to structural models of how these special tubulins may be involved in protein-protein contacts that affect microtubule self-assembly. delta-tubulin most likely interacts longitudinally with alpha-tubulin at the minus ends of microtubules, while epsilon-tubulin most likely binds to the plus end of beta. structure is 0.36 A˚ and 0.34 A˚ for MI-181 and C2, respectively.15 These results indicate that no large structural rearrangements occur in b-tubulin when bound to MI-181 or C2.

In a microtubule structure, tubulin monomers are linked both at their ends and along their sides (laterally). This means that microtubules are quite stable along their lengths. Since the tubulin subunits are always linked in the same direction, microtubules have two distinct ends, called the plus (+) and minus (-) ends Comparing α-tubulin from the crystal structure of bent tubulin bound to a stathmin-like domain (PDB:1SA0, (Ravelli et al., 2004)) with the GMPCPP and GDP models, indicates that upon hydrolysis the α-tubulin intermediate domain within the microtubule undergoes a shift similar to that reported for the straight to bent transition, but no. The structure of α‑β‑tubulin dimers and the organization of dimers in microtubules is known. Microtubule assembly is initiated by addition of α‑β‑tubulin dimers onto a scaffold formed by the γ‑tubulin ring complex (γ‑TuRC) The TTL-tubulin structure further illustrates how the enzyme binds the functionally crucial C-terminal tail sequence of α-tubulin and how this interaction catalyzes the tyrosination reaction. It also reveals how TTL discriminates between α- and β-tubulin, and between different post-translationally modified forms of α-tubulin

Additionally, although most research on tubulin's structure has been focused on the protein's globular domains, several recent studies suggest that the charged, flexible tails of tubulins may. Bacteriophage ΦKZ encodes a tubulin/FtsZ homologue, TubZ, similar to 201Φ2-1 PhuZ. We have resolved crystal structures of ΦKZ TubZ as both a monomer and a protofilament. ΦKZ TubZ undergoes structural changes only at its surface during polymerisation. Electron microscopy shows that ΦKZ TubZ forms intertwined helical filaments in vitro. This feature is common to other TubZs in Bacillus. GTP-tubulin subunits at the ends, the loss of which results in rapid depolymerization.

  3. Such a sandwich of αTAT1 between tubulin structures could be obtained if the enzyme either had more than one tubulin binding site per molecule (e.g., one site could bind the globular part of the tubulin structure, and the other could interact with the acidic C-tails of tubulin) or by oligomerization of the enzyme (e.g., dimers for which.
  4. These studies, which we review here, underscore the importance of GTP hydrolysis-induced changes in tubulin structure as microtubules assemble, and highlight the fact that each aspect of microtubule behavior is the output of complex, multi-step processes. Although this body of work moves us closer to appreciating the key features of microtubule.
  5. Paclitaxel (Taxol®) is a first-line chemotherapeutic drug that promotes the curved-to-straight conformational transition of tubulin, an activation step that is necessary for microtubule formation.

It has been proposed that one of the mechanisms of taxane-site ligand-mediated tubulin activation is modulation of the structure of a switch element (the M-loop) from a disordered form in dimeric tubulin to a folded helical structure in microtubules. Here, we used covalent taxane-site ligands, including cyclostreptin, to gain further insight into this mechanism Microtubules (MTs) are fundamental structural elements in the cytoskeleton of eukaryotic cells. Their unique mechanical properties depend on the properties of the tubulin dimer, its interactions with surrounding dimers and the geometric organizatio The αβ-tubulin dimer assembles dynamically forming these hollow cylindrical structures.

Of key importance is the structural and functional analysis of γ-tubulin complexes, which act in vivo to nucleate MT growth. Although central to all MT nucleation, the γ-tubulin small complex (γTuSC) is a surprisingly poor MT nucleator. We have determined the structure of the isolated yeast γTuSC by single-particle EM (electron microscopy) A typical microtubule is a hollow water-filled tube with an outer diameter of 25 nm and an inner diameter of 15 nM. Alpha-beta heterodimers associate head-to-tail to form protofilaments running lengthwise along the microtubule wall with the beta-tubulin subunit facing the microtubule plus end conferring a structural polarity Microtubules are made up of repeating units of α/β- tubulin heterodimers, which are assembled on a γ-tubulin ring complex (a complex of γ-tubulin and other protein components), during the nucleation phase.. Tubulin. Tubulin is a small globular protein found in all eukaryotic cells. The tubulin family represents about 3-4% of the total protein content in a cell and its members include α.
