 Cytoplasmic expression in most tissues, most abundant in ciliated cells and peripheral nerves.

DATA RELIABILITY

Data reliability
description

 Antibody staining mainly not consistent with RNA expression data. Pending external verification. Caution, targets protein from more than one gene. External characterization data supports antibody staining.

Reliability score

 Supported based on 2 antibodies.

Description

 Tubulin, beta 2B class IIb (HGNC Symbol)

Entrez gene 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]
