Fig. 1: Schematic of microtubule structural properties.

A Schematic representation of a growing microtubule. Curved GTP-tubulin heterodimers are incorporated at the microtubule plus (+) end, forming the GTP cap (indicated by orange β-tubulins). GTP-tubulin is gradually lost towards the minus (−) end due to GTP hydrolysis, causing the microtubule shaft to contain GDP-tubulin (indicated by gray β-tubulins). B, C Schematic representations illustrating the two main microtubule lattice parameters, dimer rise (B) and protofilament twist (C).
