It has been two decades since the yeast Ypt1 and Sec4 proteins and the mammalian Rab (Ras-related proteins in brain) GTPases were first identified as evolutionarily conserved, essential regulators of… (More)
Myotubularins constitute a ubiquitous family of phosphatidylinositol (PI) 3-phosphatases implicated in several neuromuscular disorders. Myotubularin [myotubular myopathy 1 (MTM1)] PI 3-phosphatase is… (More)
The Rab7 GTPase is a key regulator of late endocytic membrane transport and autophagy. Rab7 exerts temporal and spatial control over late endocytic membrane transport through interactions with… (More)
During inflammation polymorphonuclear neutrophils (PMNs) traverse venular walls, composed of the endothelium, pericyte sheath and vascular basement membrane. Compared to PMN transendothelial… (More)
Phosphatidylinositol transfer proteins (PITPs) in yeast co-ordinate lipid metabolism with the activities of specific membrane trafficking pathways. The structurally unrelated metazoan PITPs (mPITPs),… (More)
Two different human diseases, X-linked myotubular myopathy and Charcot-Marie-Tooth disease, result from mutant MTM1 or MTMR2 lipid phosphatases. Although events involved in endosomal PI(3)P and… (More)
