The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use at an assay dependent concentration. Predicted molecular weight: 50 kDa.|
FunctionTubulin 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.
Tissue specificityUbiquitously expressed with highest levels in spleen, thymus and immature brain.
Involvement in diseaseCortical dysplasia, complex, with other brain malformations 6
Skin creases, congenital symmetric circumferential, 1
Sequence similaritiesBelongs to the tubulin family.
DomainThe highly acidic C-terminal region may bind cations such as calcium.
modificationsSome 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.

Lysis Buffer was 1% Triton X-100, 20mM TrisHCl pH 7.5, 10mM EGTA, 150mM NaCl, protease inhibitors. The image was acquired by scanning the blot with a FLA-9000 Starion laserscanner at 300V and 200µm resolution. The above mentioned exposure time is just the time it took to scan the blot but does not correlate to signal intensity.
