TUBB2B - tubulin beta 2B class IIb Gene

Homo sapiens

Also known as CDCBM7; PMGYSA; bA506K6.1

Gene ID: 347733 | Gene type: protein coding

About TUBB2B

Cytogenetic location: 6p25.2 Genomic coordinates (GRCh38): 6:3,224,277-3,227,653 (from NCBI)

This gene has 5 transcripts (splice variants), 188 orthologues, 23 paralogues and is associated with 7 phenotypes. Biased expression in brain (RPKM 233.4), bone marrow (RPKM 22.7) and 11 other tissues.

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, Mar 2010]
