功能Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.
组织特异性Ubiquitously expressed with highest levels in spleen, thymus and immature brain.
疾病相关Cortical dysplasia, complex, with other brain malformations 6 Skin creases, congenital symmetric circumferential, 1
序列相似性Belongs to the tubulin family.
结构域The highly acidic C-terminal region may bind cations such as calcium.
翻译后修饰Some glutamate residues at the C-terminus are polyglutamylated, resulting in polyglutamate chains on the gamma-carboxyl group (PubMed:26875866). Polyglutamylation plays a key role in microtubule severing by spastin (SPAST). SPAST preferentially recognizes and acts on microtubules decorated with short polyglutamate tails: severing activity by SPAST increases as the number of glutamates per tubulin rises from one to eight, but decreases beyond this glutamylation threshold (PubMed:26875866). Some glutamate residues at the C-terminus are monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human. Monoglycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella). Both polyglutamylation and monoglycylation can coexist on the same protein on adjacent residues, and lowering glycylation levels increases polyglutamylation, and reciprocally. The precise function of monoglycylation is still unclear. Phosphorylated on Ser-172 by CDK1 during the cell cycle, from metaphase to telophase, but not in interphase. This phosphorylation inhibits tubulin incorporation into microtubules.
Immunocytochemistry/Immunofluorescence analysis of 3T3 mouse embryonal fibroblast cells labelling beta Tubulin with ab7792 at 2 μg/mL. A Cy®5 conjugated goat anti-mouse IgM was used as the secondary antibody. Nuclei were counterstained with DAPI (blue).
Overlay histogram showing HeLa cells stained with ab7792 (red line). The cells were fixed with methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100® for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab7792, 1µg/1x10^6 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgM [ICIGM] (ab91545, 2µg/1x10^6 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Triton X-100® used under the same conditions.
