Description
Product Characteristics:
GEF-H1 is a Rho guanine nucleotide exchange factor that localizes to microtubules and regulates Rho activity in response to microtubule destabilization (loss of interaction between GEF-H1 and microtubules leads to activation of Rho). This protein has also been shown to localize to tight junctions and modulate polarized cell permeability.
Subcellular location: Cytoplasm, Cell membrane

Target Information: Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein may form complex with G proteins and stimulate rho-dependent signals. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Jun 2009]
