Cell localization:Cytoplasm.This gene encodes a beta tubµLin protein. This protein forms a dimer with alpha tubµLin and acts as a structural component of microtubµLes. Mutations in this gene cause cortical dysplasia, complex, with other brain malformations 6. Alternative splicing resµLts in mµLtiple splice variants. There are mµLtiple pseudogenes for this gene on chromosomes 1, 6, 7, 8, 9, and 13. [provided by RefSeq, Jun 2014],
