Protein Name:
Tubulin beta-3 chain
|
UniprotKB/SwissProt ID: Q9ERD7 (Q9ERD7)
Gene Name:
Tubb3
Organism: Mus musculus (Mouse)
Function: Tubulin is the major constituent of microtubules, a cylinder consisting of laterally associated linear protofilaments composed of alpha- and beta-tubulin heterodimers (By similarity). Microtubules grow by the addition of GTP-tubulin dimers to the microtubule end, where a stabilizing cap forms (By similarity). Below the cap, tubulin dimers are in GDP-bound state, owing to GTPase activity of alpha-tubulin (By similarity). TUBB3 plays a critical role in proper axon guidance and maintenance (PubMed:20074521). 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 (PubMed:28483977). Plays a role in dorsal root ganglion axon projection towards the spinal cord (By similarity)
