Dysregulated phosphorylation of Rab GTPases by LRRK2 induces neurodegeneration
Background Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of familial and sporadic Parkinson’s disease (PD). Elevated kinase activity is associated with LRRK2 toxicity, but the substrates that mediate neurodegeneration remain

Topological and functional properties of the small GTPases protein interaction network. [PDF]
Small GTP binding proteins of the Ras superfamily (Ras, Rho, Rab, Arf, and Ran) regulate key cellular processes such as signal transduction, cell proliferation, cell motility, and vesicle transport.

Thermodynamic bounds on the ultra- and infra-affinity of Hsp70 for its substrates [PDF]
The 70 kDa Heat Shock Proteins Hsp70 have several essential functions in living systems, such as protecting cells against protein aggregation, assisting protein folding, remodeling protein complexes and driving the translocation into organelles.

Dynamin- and Rab5-Dependent Endocytosis of a Ca2+-Activated K+ Channel, KCa2.3 [PDF]
Regulation of the number of ion channels at the plasma membrane is a critical component of the physiological response. We recently demonstrated that the Ca2+-activated K+ channel, KCa2.3 is rapidly endocytosed and enters a Rab35- and EPI64C-dependent ...

RAB-like 2 has an essential role in male fertility, sperm intra-flagellar transport, and tail assembly. [PDF]
A significant percentage of young men are infertile and, for the majority, the underlying cause remains unknown. Male infertility is, however, frequently associated with defective sperm motility, wherein the sperm tail is a modified flagella/cilia ...

Characterization of the Populus Rab family genes and the function of PtRabE1b in salt tolerance
Background Rab proteins form the largest family of the Ras superfamily of small GTP-binding proteins and regulate intracellular trafficking pathways. However, the function of the Rab proteins in woody species is still an open question.

The rab3A-22A chimera prevents sperm exocytosis by stabilizing open fusion pores [PDF]
At the final stage of exocytotis, a fusion pore opens between the plasma and a secretory vesicle membranes; typically, when the pore dilates the vesicle releases its cargo.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]
RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

TBC1D9B functions as a GTPase-activating protein for Rab11a in polarized MDCK cells [PDF]
Rab11a is a key modulator of vesicular trafficking processes, but there is limited information about the guanine nucleotide-exchange factors and GTPase-activating proteins (GAPs) that regulate its GTP-GDP cycle. We observed that in the presence of Mg(2+)
