Deregulation of Rab and Rab Effector Genes in Bladder Cancer
Growing evidence indicates that Rab GTPases, key regulators of intracellular transport in eukaryotic cells, play an important role in cancer. We analysed the deregulation at the transcriptional level of the genes encoding Rab proteins and Rab-interacting proteins in bladder cancer pathogenesis, distinguishing between the two main progression pathways so far identified in bladder cancer: the Ta ...
متن کاملReversible phosphocholination of Rab proteins by Legionella pneumophila effector proteins.
The Legionella pneumophila protein AnkX that is injected into infected cells by a Type IV secretion system transfers a phosphocholine group from CDP-choline to a serine in the Rab1 and Rab35 GTPase Switch II regions. We show here that the consequences of phosphocholination on the interaction of Rab1/Rab35 with various partner proteins are quite distinct. Activation of phosphocholinated Rabs by ...

متن کاملGEF-effector interactions
Members of the Arf family of small GTP-binding proteins, or GTPases, are activated by guanine nucleotide exchange factors (GEFs) that catalyze GDP release from their substrate Arf, allowing GTP to bind. In the secretory pathway, Arf1 is first activated by GBF1 at the cis-Golgi, then by BIG1 and BIG2 at the trans-Golgi and trans-Golgi network (TGN). Upon activation, Arf1-GTP interacts with effec...
متن کاملStructure-Function Analyses of the Interactions between Rab11 and Rab14 Small GTPases with Their Shared Effector Rab Coupling Protein (RCP).
Rab GTPases recruit effector proteins, via their GTP-dependent switch regions, to distinct subcellular compartments. Rab11 and Rab25 are closely related small GTPases that bind to common effectors termed the Rab11 family of interacting proteins (FIPs). The FIPs are organized into two subclasses (class I and class II) based on sequence and domain organization, and both subclasses contain a highl...
