Focus on the Small GTPase Rab1: A Key Player in the Pathogenesis of Parkinson’s Disease

Abstract: Parkinson’s disease (PD) is the second most frequent neurodegenerative disease. It is characterized by the loss of dopaminergic neurons in the substantia nigra and the formation of large aggregates in the survival neurons called Lewy bodies, which mainly contain α-synuclein (α-syn). The cause of cell death is not known but could be due to mitochondrial dysfunction, protein homeostasis failure, and alterations in the secretory/endolysosomal/autophagic pathways. Survival nigral neurons overexpress the small GTPa… Show more

“…The reason why these neurons are particularly affected in PD remains unclear. Golgi fragmentation as a result of defective Rab1‐dependent ER‐to‐Golgi transport may significantly alter homeostasis of dopaminergic neurons triggering cell death (Martínez‐Menárguez et al, 2021).…”

“…Rab1b is required for vesicle transport between the ER and the Golgi [28]. Given the unbalance of Rab1b expression and compaction of the Golgi in cells lacking sacsin, Rab1b association with Golgi or ER was characterized by measuring the PCC of ectopically expressed Rab1b-EGFP (to avoid nonspecific Rab1 antibody labeling) with GM130 or KDEL, markers of Golgi and ER, respectively.…”

“…Small GTPases were identified in proteomes of virion preparations (HCMV proteomes 1–5 and HSV-1 proteome 6), NVEPs (NV), l EVs (L), and s EVs (S) (proteome 7). The reported localization in membrane organelles of non-infected cells is shown by a color code to illustrate the preferred localization [ 49 , 59 , 60 , 69 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 , 130 ].
