Disease
TBB2B_HUMAN Congenital fibrosis of extraocular muscles;Polymicrogyria due to TUBB2B mutation. The disease is caused by mutations affecting the gene represented in this entry. The disease may be caused by mutations affecting the gene represented in this entry. Defects in TUBB2B may be involved in cerebellar ataxia, mental retardation, and dysequilibrium syndrome (CAMRQ).[1]
Function
TBB2B_HUMAN Tubulin is the major constituent of microtubules (PubMed:23001566, PubMed:28013290, PubMed:26732629). 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 (By similarity). Plays a critical role in proper axon guidance in both central and peripheral axon tracts (PubMed:23001566). Implicated in neuronal migration (PubMed:19465910).[2] [3] [4] [5]
