MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a beta isoform of tubulin, which binds GTP and is a major component of microtubules. This gene is highly similar to TUBB2A and TUBB2C. Defects in this gene are a cause of asymmetric polymicrogyria. [provided by RefSeq, Mar 2010]
PHENOTYPE: Mice homozygous for an ENU-induced mutation exhibit mild hydroencephaly, telencephalon dysmorphology, a small olfactory bulb and prenatal lethality. Mice heterozygous for this mutation exhibit hyperactivity, reduced fertility and abnormal cortex. [provided by MGI curators]
