What is beta tubulin?
Beta-Tubulin is a subunit of tubulin. Tubulin is one of several members of a small family of globular proteins. It is the major constituent of microtubules. There are two of most common members of the tubulin family: alpha-tubulin and beta-tubulin, and together their dimers form microtubules.
Do humans have tubulin?
β1-tubulin, sometimes called class VI β-tubulin, is the most divergent at the amino acid sequence level. It is expressed exclusively in megakaryocytes and platelets in humans and appears to play an important role in the formation of platelets.
What is TUBB3 syndrome?
Heterozygous missense mutations in β-tubulin isotype III (TUBB3), which is exclusively expressed in neurons (1), result in the TUBB3 syndrome, which includes congenital fibrosis of the extraocular muscle type 3 (CFEOM3), intellectual impairments, facial paralysis and/or an axonal sensorimotor neuropathy (2,3).

What is the relationship between a microtubule and alpha beta tubulin dimers?
A microtubule is a polar structure, its polarity arising from the head-to-tail arrangement of the α- and β-tubulin dimers in a protofilament. Because all protofilaments in a microtubule have the same orientation, one end of a microtubule is ringed by α-tubulin, while the opposite end is ringed by β-tubulin.
In which tubulin protein is present?
The tubulin family of proteins are vital components of the eukaryotic cytoskeleton and are the main constituent of microtubules in living cells. The tubulin proteins α- and β polymerize into long chains or filaments that form microtubules, an essential element of the eukaryotic cytoskeleton.
Is tubulin present in Centriole?
Thus, ε-tubulin is conserved in organisms with triplet microtubules in their centrioles and basal bodies with the exception of Drosophila melanogaster.
What motor is associated with microfilaments?
Microfilaments are the thinnest component of the cytoskeleton.: Microfilaments are made of two intertwined strands of actin. Actin is powered by ATP to assemble its filamentous form, which serves as a track for the movement of a motor protein called myosin.
Where can I find list of beta tubulin mutations?
Cell Motil Cytoskeleton 22:170-4 Cruz et al. 1997. Microbiology 143:2003-8 Jung et al. 1992. Cell Motil Cytoskeleton 22:170-4 Ma et al. 2003. Appl Environ Microbiol 69:7145-52 Cooley and Caten. 1993. Mol Gen Genet 237:58-64 Gupta et al. 2001. Cell Motil Cytoskeleton 49:67-77 Gupta et al. 2001.
What kind of mutations in TUBB5 cause microcephaly?
Mutations in the β-tubulin gene TUBB5 cause microcephaly with structural brain abnormalities The formation of the mammalian cortex requires the generation, migration, and differentiation of neurons.
How does TQ Affect Alpha and beta tubulin?
TQ induced a concentration- and time-dependent degradation of alpha/beta tubulin in both cancer cell types. Allele frequencies between a group of 191 ITP patients & controls showed no direct aetiological role for SNP (R307H), but it was associated with immunomodulatory treatment failure.
How are mutations in TUBB1 related to resistance?
In the current study, molecular mechanism of these resistance causing mutations in TUBB1 was explored using molecular docking, molecular dynamics simulation, binding energy estimation, free energy decomposition, principle component analysis and free energy landscape methods. Data suggest a looser binding of the ligand in tubulin mutants.
