Rab15 differentially regulates early endocytic trafficking.
-
Wild-type and GTP-locked (Q67L) RAB15 inhibit fluid-phase and receptor-mediated endocytosis
"Wild-type HArab15 and its constitutively active, GTP-bound mutant (Q67L) reduce fluid phase and receptor-mediated endocytosis without affecting the rate of recycling from early endosomal compartments"
-
RAB15 reduces homotypic early endosome fusion
"Inhibition of early endocytosis appears to be due to a reduction in the rate of homotypic early endosome fusion"
-
Inactive mutants (T22N, N121I) stimulate endocytosis and differentially regulate recycling
"the two constitutively inactive mutants, GDP-bound HArab15-T22N and the non-nucleotide binding mutant HArab15-N121I, differentially regulate the transit of fluid phase and receptor-mediated endocytic tracers through early/sorting endosomes"
-
RAB15 counteracts Rab5-stimulated endocytosis
"HArab15 may counteract the reported stimulatory effect of Rab5 on early endocytosis"
-
Establishes RAB15 as a negative regulator of early endocytosis
"Our data indicate that HArab15 differentially regulates distinct steps in membrane trafficking through early/sorting and pericentriolar recycling endosomes"
Rab15 effector protein: a novel protein for receptor recycling from the endocytic recycling compartment.
-
Identified REP15 as a specific effector for RAB15-GTP
"we identified the novel protein Rab15 effector protein (REP15) as a binding partner for Rab15-GTP"
-
REP15 localizes to the ERC with Rab11, not to sorting endosomes
"REP15 is compartment specific, colocalizing with Rab15 and Rab11 on the endocytic recycling compartment but not with Rab15, Rab4, or early endosome antigen 1 on sorting endosomes"
-
REP15 regulates transferrin receptor recycling from the ERC
"REP15 overexpression and small interfering RNA-mediated depletion inhibited transferrin receptor recycling from the endocytic recycling compartment"
-
RAB15-REP15 pathway is specific for slow ERC-mediated recycling, not fast SE recycling
"REP15 overexpression and small interfering RNA-mediated depletion inhibited transferrin receptor recycling from the endocytic recycling compartment, without affecting receptor entry into or recycling from sorting endosomes"
-
Demonstrates compartment-specific effector interactions
"Our data identify REP15 as a compartment-specific protein for receptor recycling from the endocytic recycling compartment"
Functional dissection of Rab GTPases involved in primary cilium formation.
-
Systematic screen of human Rabs for cilium localization and function
"To find Rabs involved in primary cilium formation, the 39 predicted human RabGAPs were tested for their ability to prevent primary cilium formation"
-
Rab8a is the sole Rab enriched at primary cilia
"Screening the human Rabs revealed that Rab8a was the only Rab that could be detected on primary cilia when expressed as a GFP-tagged protein"
-
Rab8a, Rab17, and Rab23 (but not RAB15) are required for primary cilium formation
"dominant-negative forms of Rab8a, -17, and -23, but not the other Rabs tested, including Rab8b, prevented primary cilium formation"
-
This paper does NOT support RAB15 localization to cilia
"Rab8a is the sole Rab on primary cilia"
Large-scale proteomics and phosphoproteomics of urinary exosomes.
-
High-throughput proteomic identification of RAB15 in urinary exosomes
"Here, we used LC-MS/MS to profile the proteome of human urinary exosomes"
-
Identified 1132 proteins total in exosome proteome
"Overall, the analysis identified 1132 proteins unambiguously"
-
Detection does not indicate functional localization
"exosome analysis is a potential approach to discover urinary biomarkers"
A complete Rab screening reveals novel insights in Weibel-Palade body exocytosis.
-
RAB15 localizes to Weibel-Palade body limiting membrane
"Apart from Rab3 and Rab27, we identified three additional Rabs, Rab15 (a previously reported endocytic Rab), Rab33 and Rab37, on the WPB limiting membrane"
-
RAB15 knockdown reduces WPB exocytosis
"A knockdown approach using siRNAs showed that among these five WPB Rabs only Rab3, Rab27 and Rab15 are required for exocytosis"
-
RAB15 cooperates with Rab27a in WPB secretion
"Intriguingly, we found that Rab15 cooperates with Rab27a in WPB secretion"
-
Munc13-4 is a shared effector of RAB15 and Rab27a
"a specific effector of Rab27, Munc13-4, appears to be also an effector of Rab15 and is required for WPB exocytosis"
-
Establishes RAB15 role in regulated secretion beyond endocytic recycling
"WPB secretion requires the coordinated function of a specific group of Rabs"
bMERB domains are bivalent Rab8 family effectors evolved by gene duplication.
-
RAB15-GTP interacts with MICAL1, MICAL3, MICALCL, EHBP1, and EHBP1L1
Rep15 interacts with several Rab GTPases and has a distinct fold for a Rab effector.
Deep research review of RAB15 function
-
RAB15 localizes to sorting/early endosomes and perinuclear endocytic recycling compartment
"RAB15 localizes to sorting/early endosomes (SEs/EEs) and the perinuclear endocytic recycling compartment (ERC), where it co-resides with Rab4/5 on SEs and Rab11 on ERC"
-
RAB15 regulates endocytic sorting and recycling of the transferrin receptor
"RAB15 regulates endocytic sorting and recycling of the transferrin receptor (TfR), helping partition cargo between rapid recycling from SEs and slower recycling via the ERC"
-
REP15 was identified as a direct specific RAB15 effector
"REP15 was identified as a direct, specific RAB15 effector that prefers RAB15-GTP, colocalizes perinuclearly with RAB15, and regulates TfR recycling"
