TTBK2 down-regulates GluK2 activity by decreasing the receptor protein abundance in the cell membrane via RAB5-dependent endocytosis, an effect that may protect against neuroexcitotoxicity. PubMed:27607061
It is this abnormal rab5 activation that causes protein and lipid accumulation in endosomes, slowed lysosomal degradation of endocytic cargoes,endosome swelling (Cataldo et al. 2008), and disrupted retrograde transport of endosomes (S Kim and RA Nixon, unpubl.). PubMed:22908190

Pathological Rab5 activation driving endocytic dysfunction in AD may negatively impact longterm potentiation (LTP) and long-term depression (LTD) aspects of synaptic plasticity closely associated with learning and memory (Kessels et al. 2009) PubMed:22908190

Interactions between FAD-mutant forms of APP and APP binding protein (APP-BP1) on endosomes also initiate pathological rab5 activation, which was shown to promote a neuronal apoptosis cascade (Laifenfeld et al. 2007). PubMed:22908190
Genes related to endocytosis, such as Rab5,Rab7, and Rab4, are among the earliest groups to showup-regulated transcription in AD(Ginsberg et al. 2010), and their corresponding proteins are abnormally recruited to endosomes, where they promote fusion and abnormal enlargement of early and late endosomes (Cataldo et al. 1997, 2008).

Recently, these effects of increased App dosage were shown to be mediated specifically by the b-cleaved carboxy-terminal fragment of APP, bCTF (Jiang et al. 2010), which binds to a complex of signaling molecules on endosomes that pathologically activates rab5 (S Kim and RA Nixon, unpubl.). PubMed:22908190
Pathological rab5 activation, which in Down syndrome is dependent on bCTF generation (Jiang et al. 2010), can up-regulate endocytosis in a manner functionally equivalent to the elevated endocytosis associated with increased synaptic activity, which is considered a source of Ab generation (Cirrito et al. 2008). PubMed:22908190
Conversely, deletion of the neuronal rab5 GEF, rin1, reduces rab5 activation, increases LTP induction in the amygdala, and enhances fear learning and memory, most likely by increasing surface levels of AMPA receptors (Dhaka et al. 2003). PubMed:22908190

Interestingly, genetic or pharmacological activation of RAB5 countered neurodegeneration in mouse C9ORF72 models of ALS and FTD 187 . PubMed:30116051

Endocytic pathway up-regulation in AD stemming in part from pathological rab 5 activation generates higher levels of Ab (Mathews et al. 2002; Grbovic et al. 2003) that must be cleared in part by lysosomes. PubMed:22908190
