Protein

Tubulin beta chain

Gene
N/A
Organism
Sus scrofa (Pig)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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 modificationi

Some glutamate residues at the C-terminus are either polyglutamylated or polyglycylated. These 2 modifications occur exclusively on glutamate residues and result in either polyglutamate or polyglycine chains on the gamma-carboxyl group. Glycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella) whereas glutamylation is prevalent in neuronal cells, centrioles, axonemes, and the mitotic spindle. Both modifications can coexist on the same protein on adjacent residues, and lowering polyglycylation levels increases polyglutamylation, and reciprocally. The precise function of such modifications is still unclear but they are regulate the assembly and dynamics of axonemal microtubules (By similarity).By similarity

Interactioni

Subunit structurei

Dimer of alpha and beta chains. 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 usually have 13 protofilaments but different protofilament numbers can be found in some organisms and specialized cells.
