DESCRIPTION

Also known as TBB5_HUMAN, TUBB, TUBB5. 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. Heterodimer of alpha and beta chains (PubMed:26637975). 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. Interacts with PIFO (PubMed:20643351). Interacts with DIAPH1 (PubMed:23325789). Interacts with MX1 (By similarity). May interact with RNABP10 (By similarity). Interacts with CFAP157 (By similarity).
