miR‐9 Restricts Insulin Secretion by Targeting Rab34, Which Mediates Lysosomal Degradation of Proinsulin

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Insulin secretion is a complex, vesicular transport process. Rab34 is a key regulator of intracellular vesicle transport; however, its role in insulin secretion has not yet been reported. miRNA‐9 is vital for the development and progression of the diagnosis and treatment of type 2 diabetes. This study aimed to investigate whether miR‐9 targets

The effector domain of Rab6, plus a highly hydrophobic C terminus, is required for Golgi apparatus localization [PDF]

, 1994
C-terminal lipid modifications are essential for the interaction of Ras-related proteins with membranes. While all Ras proteins are farnesylated and some palmitoylated, the majority of other Ras-related proteins are geranylgeranylated.

Rab geranylgeranyl transferase. A multisubunit enzyme that prenylates GTP-binding proteins terminating in Cys-X-Cys or Cys-Cys.

Journal of Biological Chemistry, 1992
Rab proteins are membrane-bound prenylated GTP-binding proteins required for the targeted movement of membrane vesicles from one organelle to another. In the current paper we have characterized and purified an enzyme that attaches geranylgeranyl residues to Rab proteins that bear the COOH-terminal sequence Cys-X-Cys (such as Rab3A) and Cys-Cys (such as

Dynamics of the CD9 interactome during bacterial infection of epithelial cells by proximity labelling proteomics

The FEBS Journal, EarlyView.
We describe the CD9 interactome in epithelial cells for the first time. The interactome is diverse and dynamic and changes dependent on infection with specific bacteria. We validate these data by showing functional interaction between CD9 with CD44 or CD147. We therefore demonstrate that CD9 is a universal organiser of bacterial adhesion platforms able

Signal transduction gRABs attention [PDF]

, 2006
Rab proteins are small GTPases involved in the regulation of vesicular membrane traffic. Research done in the past years has demonstrated that some of these proteins are under the control of signal transduction pathways.

rab GTP-binding proteins with three different carboxyl-terminal cysteine motifs are modified in vivo by 20-carbon isoprenoids.

Journal of Biological Chemistry, 1992
p21ras and several other ras-related GTP-binding proteins are modified post-translationally by addition of 15-carbon farnesyl or 20-carbon geranylgeranyl isoprenoids to cysteines within a conserved carboxyl-terminal sequence motif, Caa(M/S/L), where a is an aliphatic amino acid.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Rab11a Controls Cell Shape via C9orf72 Protein: Possible Relationships to Frontotemporal Dementia/Amyotrophic Lateral Sclerosis (FTDALS) Type 1

Pathophysiology
Abnormal nucleotide insertions of C9orf72, which forms a complex with Smith–Magenis syndrome chromosomal region candidate gene 8 (SMCR8) protein and WD repeat-containing protein 41 (WDR41) protein, are associated with an autosomal-dominant ...

Rab31 expression levels modulate tumor-relevant characteristics of breast cancer cells

Molecular Cancer, 2012
Background Rab proteins constitute a large family of monomeric GTP-binding proteins that regulate intracellular vesicle transport. Several Rab proteins, including rab31, have been shown to affect cancer progression and are related with prognosis in ...
