Small GTPases in Acrosomal Exocytosis
, 2015 Regulated exocytosis employs a conserved molecular machinery in all secretory cells. Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) and Rab superfamilies are members of this machinery. Rab proteins are small GTPases that organize membrane microdomains on organelles by recruiting specific effectors that strongly influence ...

Small GTPases in peroxisome dynamics
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2016 In this review article, we summarize current knowledge on peroxisome biogenesis/functions and the role that small GTPases may play in these processes. Precise intracellular distribution of cell organelles requires their regulated association to microtubules and the actin cytoskeleton.

Isoprenoids, small GTPases and Alzheimer's disease [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2010 The mevalonate pathway is a crucial metabolic pathway for most eukaryotic cells. Cholesterol is a highly recognized product of this pathway but growing interest is being given to the synthesis and functions of isoprenoids. Isoprenoids are a complex class of biologically active lipids including for example, dolichol, ubiquinone, farnesylpyrophosphate ...

METTL13 methylation of eEF1A increases translational output to promote tumorigenesis [PDF]
, 2019 Increased protein synthesis plays an etiologic role in diverse cancers. Here, we demonstrate that METTL13 (methyltransferase-like 13) dimethylation of eEF1A (eukaryotic elongation factor 1A) lysine 55 (eEF1AK55me2) is utilized by Ras-driven cancers to ...

Small GTPases in platelet membrane trafficking [PDF]
Platelets, 2018 Our understanding of fundamental biological processes within platelets is continually evolving. A critical feature of platelet biology relates to the intricate uptake, packaging and release of bioactive cargo from storage vesicles, essential in mediating a range of classical (haemostasis/thrombosis) and non-classical (regeneration/inflammation ...

Dissection of GTPase activating proteins reveals functional asymmetry in the COPI coat of budding yeast. [PDF]
, 2019 The Arf GTPase controls formation of the COPI vesicle coat. Recent structural models of COPI revealed the positioning of two Arf1 molecules in contrasting molecular environments.

Functional specialization of the yeast Rho1 GTP exchange factors [PDF]
, 2012 Rho GTPases are regulated in complex spatiotemporal patterns that may be dependent, in part at least, on the multiplicity of their GTP exchange factors (GEFs).

GAP activity, but not subcellular targeting, is required for Arabidopsis RanGAP cellular and developmental functions [PDF]
, 2015 The Ran GTPase activating protein (RanGAP) is important to Ran signaling involved in nucleocytoplasmic transport, spindle organization, and postmitotic nuclear assembly.
