What's a GeneRIF?

Here, using EGF/EGFR endocytosis as a model and confocal microscopy of fixed and live cells, we provide evidence favoring EEA1-vesicles being pre-existed vesicular compartment, that maintains its resident proteins' level and is sensitive to biosynthetic, but not endocytic pathway disturbance.
Title: Functional cycle of EEA1-positive early endosome: Direct evidence for pre-existing compartment of degradative pathway.
Rab5C and EEA1 in the early endosomal pathway, and Rab7A and lysobisphosphatidic acid in the late endosomal pathway, are important for trafficking of phosphorothioate Antisense oligonucleotides and facilitate their escape from endolysosomal compartments after Stabilin-mediated internalization.
Title: Endosomal Escape of Antisense Oligonucleotides Internalized by Stabilin Receptors Is Regulated by Rab5C and EEA1 During Endosomal Maturation.
This also suggests that this pathway is involved in EEA1-vesicles biogenesis.
Title: EEA1 CARRYING VESICLES ARE NOT AUTOPHAGOSOMES IN SERUM-DEPRIVED HeLa CELLS.
identification of allergic bronchopulmonary aspergillosis -associated variants in EEA that have functional effects on macrophage phagocytosis and phagolysosome acidification of A. fumigatus conidia.
Title: Mutations in EEA1 are associated with allergic bronchopulmonary aspergillosis and affect phagocytosis of Aspergillus fumigatus by human macrophages.
results suggest a new mechanism in which Rab5 induces a change in flexibility of EEA1, generating an entropic collapse force that pulls the captured vesicle towards the target membrane to initiate docking and membrane fusion
Title: An endosomal tether undergoes an entropic collapse to bring vesicles together.
EEA1 mobility on endosomes is decreased upon stimulation of EGF receptor endocytosis in HeLa cells
Title: Mobility of tethering factor EEA1 on endosomes is decreased upon stimulation of EGF receptor endocytosis in HeLa cells.
Under the regulation of Rab5, the fused vesicles are targeted to early endosomes and thus deliver the internalized TbetaRI to the caveolin-1 and EEA1 double-positive early endosomes (caveolin-1-positive early endosomes).
Title: Internalization of the TGF-β type I receptor into caveolin-1 and EEA1 double-positive early endosomes.
In serum-deprivated HeLa cells with low endocytic activity there two types of EEA1-vesicles: the first one carries the both EEA1 and Rab5 at high levels; the second consists of weakly decorated EEA1-vesicles that can be both Rab5-positive and -negative.
Title: [Analysis of vesicle subpopulations carrying early endosomal autoantigen EEA1].
Data indicate that early endosome antigen 1 (EEA1) is important for the small GTPase Rab31-mediated enhancement of ligand-bound EGF receptor (EGFR) endocytic trafficking.
Title: Engagement of the small GTPase Rab31 protein and its effector, early endosome antigen 1, is important for trafficking of the ligand-bound epidermal growth factor receptor from the early to the late endosome.
nuclear uptake of Abeta involves the dynamin-dependent EEA1 and TGF-beta/Smad signaling pathways.
Title: HIV-1 stimulates nuclear entry of amyloid beta via dynamin dependent EEA1 and TGF-β/Smad signaling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
