Target Background

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. TUBB3 plays a critical role in proper axon guidance and maintenance. Binding of NTN1/Netrin-1 to its receptor UNC5C might cause dissociation of UNC5C from polymerized TUBB3 in microtubules and thereby lead to increased microtubule dynamics and axon repulsion. Plays a role in dorsal root ganglion axon projection towards the spinal cord.
Gene References into Functions
  1. Results demonstrated that TUBB3 mutations impair the interaction of DCC with polymerized TUBB3 in MTs and inhibit netrin-1-induced neurite outgrowth, branching and attraction. These results suggest a disease mechanism underlying TUBB3 mutation-associated axon guidance defects: mutations in TUBB3 disrupt engagement of netrin/DCC signaling with MT dynamics, resulting in specific defects of netrin-1-mediated axon projection.
