* Required Fields

Product name Anti-β I tubulin antibody
Short Description Mouse monoclonal to β I tubulin.
Description β I tubulin is a protein encoded by the TUBB1 gene which is approximately 50,3 kDa. β I tubulin is localised to the cytoplasm. It is involved in development Slit-Robo signalling, Sertoli-Sertoli cell junction dynamics, signalling in gap junctions and chaperonin-mediated protein folding. This protein falls under the beta tubulin protein family. It is one of two core protein families that heterodimerize and assemble to form microtubules. It is exists in platelets and megakaryocytes and may be involved in proplatelet production and platelet release. β I tubulin is expressed in the blood and cells of the nervous system. Mutations in the TUBB1 gene may result in macrothrombocytopaenia. STJ96939 was developed from clone 3F7 and was affinity-purified from mouse ascites by affinity-chromatography using specific immunogen. This antibody detects endogenous β I tubulin proteins.

Tubulin beta-1 chain antibody
Function 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 .
Post-translational Modifications Some glutamate residues at the C-terminus are polyglutamylated, resulting in polyglutamate chains on the gamma-carboxyl group . 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 . 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 (Probable). 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.
Cellular Localization Cytoplasm, cytoskeleton
Tissue Specificity Hematopoietic cell-specific. Major isotype in leukocytes, where it represents 50% of all beta-tubulins.

Ask us a question

I am interested in this antibody in 0.3mg size, 1mg/mL. Would it be possible to change the storage buffer to PBS and not include sodium azide?
Question by: Guest on 11 Apr 2018 12:40:00
Hello, thank you for your query. If you would like to place a custom order, the product should be at least 1 mg. There will be no additional cost for changing the storage buffer. Please contact us at for further information.
