LRRK2 secretion in exosomes is regulated by 14-3-3.
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset Parkinson's disease (PD). Emerging evidence suggests a role for LRRK2 in the endocytic pathway. Here, we show that LRRK2 is released in extracellular microvesicles (i.e. exosomes) from cells that natively express LRRK2. LRRK2 localizes to collecting duct epithelial cells in the kidney that actively secrete exosomes into...
متن کاملNuclear localization of protein kinase U-alpha is regulated by 14-3-3.
14-3-3 proteins are intracellular, dimeric molecules that bind to and modify the activity of several signaling proteins. We used human 14-3-3zeta as a bait in the yeast two-hybrid system to screen a murine embryonic cDNA library. One interacting clone was found to encode the carboxyl terminus of a putative protein kinase. The coding sequence of the human form (protein kinase Ualpha, PKUalpha) o...
متن کاملAmino acids C-terminal to the 14-3-3 binding motif in CDC25B affect the efficiency of 14-3-3 binding.
The phospho-site adapter protein 14-3-3 binds to target proteins at amino acid sequences matching the consensus motif Arg-X-X-Ser/Thr-X-Pro, where the serine or threonine residue is phosphorylated and X is any amino acid. The dual-specificity phosphatase CDC25B, which is involved in cell cycle regulation, contains five 14-3-3 binding motifs, but 14-3-3 preferentially binds to the motif at Ser30...
متن کاملMLN64 Transport to the Late Endosome Is Regulated by Binding to 14-3-3 via a Non-canonical Binding Site
MLN64 is an integral membrane protein localized to the late endosome and plasma membrane that is thought to function as a mediator of cholesterol transport from endosomal membranes to the plasma membrane and/or mitochondria. The protein consists of two distinct domains: an N-terminal membrane-spanning domain that shares homology with the MENTHO protein and a C-terminal steroidogenic acute regul...
متن کاملBinding of Kif23-iso1/CHO1 to 14-3-3 Is Regulated by Sequential Phosphorylations at Two LATS Kinase Consensus Sites
Kif23 kinesin is an essential actor of cytokinesis in animals. It exists as two major isoforms, known as MKLP1 and CHO1, the longest of which, CHO1, contains two HXRXXS/T NDR/LATS kinase consensus sites. We demonstrate that these two sites are readily phosphorylated by NDR and LATS kinases in vitro, and this requires the presence of an upstream -5 histidine residue. We further show that these s...
