Function

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 (By similarity). TUBB2B is implicated in neuronal migration. {ECO:0000250, ECO:0000269PubMed:19465910}.

Subcellular Localization

Cytoplasm, cytoskeleton {ECO:0000250}.

Disease Associations

Polymicrogyria, symmetric or asymmetric (PMGYSA) [MIM:610031]: A malformation of the cortex in which the brain surface is irregular and characterized by an excessive number of small gyri with abnormal lamination. Polymicrogyria is a heterogeneous disorder, considered to be the result of postmigratory abnormal cortical organization. {ECO:0000269PubMed:19465910}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

High expression in brain. {ECO:0000269PubMed:20191564}.
