Purification, crystallization and preliminary X-ray crystallographic analysis of mammalian MSS4-Rab8 GTPase protein complex.


ABSTRACT: Rab GTPases function as ubiquitous key regulators of membrane-vesicle transport in eukaryotic cells. MSS4 is an evolutionarily conserved protein that binds to exocytotic Rabs and facilitates nucleotide release. The MSS4 protein in complex with nucleotide-free Rab8 GTPase has been purified and crystallized in a form suitable for structure analysis. The crystals belonged to space group P1, with unit-cell parameters a = 40.92, b = 49.85, c = 83.48 A, alpha = 102.88, beta = 97.46, gamma = 90.12 degrees. A complete data set has been collected to 2 A resolution.
