Gene Gene information from NCBI Gene database.
Entrez ID 347733
Gene name Tubulin beta 2B class IIb
Gene symbol TUBB2B
Synonyms (NCBI Gene)
CDCBM7PMGYSAbA506K6.1
Chromosome 6
Chromosome location 6p25.2
Summary 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,

Protein name Tubulin beta-2B chain
Protein function Tubulin is the major constituent of microtubules, a cylinder consisting of laterally associated linear protofilaments composed of alpha- and beta-tubulin heterodimers (PubMed:23001566, PubMed:26732629, PubMed:28013290). Microtubules grow by the
