Supplementary information

Detyrosinated alpha Tubulin also known as detyrosinated tubulin or alpha tubulin is a modified form of the alpha subunit of tubulin. This protein undergoes detyrosination which entails removing the terminal tyrosine residue. Detyrosinated alpha Tubulin has an approximate molecular mass of 50 kDa. It localizes mainly in the cytoplasm and plays an important role in the stability and function of microtubules which are key components of the cytoskeleton. These modifications regulate microtubules' dynamic properties impacting cellular processes such as intracellular transport and cell division.
Biological function summary

Detyrosinated alpha Tubulin impacts important cellular functions. It is an integral part of the microtubule network. Microtubules provide structural support to the cell aiding in intracellular transport and cell shape maintenance. The detyrosination of alpha tubulin contributes to the regulation of microtubule stability which is essential for accurate chromosome segregation during mitosis. Furthermore the detyrosination influences interactions with microtubule-associated proteins and motor proteins affecting their binding affinity and activity.

Pathways

Detyrosinated alpha Tubulin is significant in cellular signaling and transport. It is an important part of the microtubule-dependent transport pathways that facilitate the movement of cellular components including vesicles and organelles. The detyrosination of alpha tubulin influences its interaction with motor proteins such as kinesins and dyneins which are responsible for directional transport along microtubules. Additionally alterations in tubulin detyrosination affect the Wnt signaling pathway impacting cellular processes such as proliferation and differentiation.

Alterations in the detyrosination of alpha Tubulin have links to neurodegenerative diseases and cancer. In neurodegenerative disorders abnormal detyrosination can disrupt axonal transport contributing to diseases like Alzheimer's. In cancer increased levels of detyrosinated alpha Tubulin can enhance cell invasiveness and metastasis. The dysregulation of tubulin detyrosination affects cellular interactions with proteins such as tau in neurodegenerative disorders and beta-catenin in cancer implicating these proteins in disease progression.

Target data

Tubulin is the major constituent of microtubules, a cylinder consisting of laterally associated linear protofilaments composed of alpha- and beta-tubulin heterodimers. Microtubules grow by the addition of GTP-tubulin dimers to the microtubule end, where a stabilizing cap forms. Below the cap, tubulin dimers are in GDP-bound state, owing to GTPase activity of alpha-tubulin.
