The Tubulin Code, from Molecules to Health and Disease.
Microtubules are essential dynamic polymers composed of α/β-tubulin heterodimers. They support intracellular trafficking, cell division, cellular motility, and other essential cellular processes. In many species, both α-tubulin and β-tubulin are encoded by multiple genes with distinct expression profiles and functionality. Microtubules are further diversified through abundant posttranslational modifications, which are added and removed by a suite of enzymes to form complex, stereotyped cellular arrays. The genetic and chemical diversity of tubulin constitute a tubulin code that regulates intrinsic microtubule properties and is read by cellular effectors, such as molecular motors and microtubule-associated proteins, to provide spatial and temporal specificity to microtubules in cells. In this review, we synthesize the rapidly expanding tubulin code literature and highlight limitations and opportunities for the field. As complex microtubule arrays underlie essential physiological processes, a better understanding of how cells employ the tubulin code has important implications for human disease ranging from cancer to neurological disorders.
期刊介绍:
The Annual Review of Cell and Developmental Biology, established in 1985, comprehensively addresses major advancements in cell and developmental biology. Encompassing the structure, function, and organization of cells, as well as the development and evolution of cells in relation to both single and multicellular organisms, the journal explores models and tools of molecular biology. As of the current volume, the journal has transitioned from gated to open access through Annual Reviews' Subscribe to Open program, making all articles published under a CC BY license.
