Human brain-expressed X-linked (BEX) members (BEX1, BEX2, BEX3, BEX4, BEX5) are all located on chromosome Xq22. They are highly conserved genes among different species (including chimp, mouse, rat, dog and human) implying their importance in cellular functions. It has been reported that BEX family members could regulate cell cycle and apoptotic signaling. Among BEX proteins, BEX4 localizes to microtubules and spindle poles, and interacts with α-tubulin (α-TUB) and sirtuin 2 (SIRT2). The overexpression of BEX4 leads to the hyperacetylation of α-TUB by inhibiting SIRT2-mediated deacetylation. BEX4 gene has been identified as a mediator of microtubule hyperacetylation through sirtuin 2 inhibition and is highly overexpressed in human cancers.
