Polymorphisms in the region of this gene have been found to be associated with spinocerebellar ataxia in some study populations. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]. * **UniProt Summary**: Possible role in intracellular signaling and cytoskeleton dynamics at the Golgi. |RhoGEF| |Rho guanyl-nucleotide exchange factor activity| |activation of GTPase activity| |regulation of Rho protein signal transduction| |regulation of Ras protein signal transduction| |regulation of small GTPase mediated signal transduction| |positive regulation of GTPase activity| |regulation of GTPase activity| |positive regulation of hydrolase activity| |regulation of hydrolase activity| |positive regulation of catalytic activity| |positive regulation of molecular function| |regulation of intracellular signal transduction| \\ === CRISPR Data === No hits were found.
