EB3 Proteins and Enzymes

EB3 is a 282 amino acid homologue of EB1, a protein known to bind APC (adenomatous polyposis coli). It has been shown to bind to tubulin in vitro and microtubules in vivo. Northern blotting shows expressions to be mainly in brain, and to a lesser degree in muscle. EB3 interacts with APCL, a homologue of the tumor suppressor APC, and this interaction may be involved in the stabilization or extension of microtubules.
