Mutant mice have impaired spatial memory, and sigma 1B-deficient humans have a severe mental retardation. In order to define these sigma 1B(-/-) 'bulk' endosomes and to determine their functions in SV recycling, we developed a protocol to separate them from the majority of the neuronal endosomes. The sigma 1B(-/-) 'bulk' endosomes proved to be classic early endosomes with an increase in the phospholipid phosphatidylinositol 3-phosphate (PI-3-P), which recruits proteins mediating protein sorting out of early endosomes into different routes. sigma 1B deficiency induced alterations in the endosomal proteome reveals two major functions: SV protein storage and sorting into endolysosomes. Alternative endosomal recycling pathways are not up-regulated, but certain SV proteins are misrouted. Tetraspanins are enriched in sigma 1B(-/-) synaptosomes, but not in their endosomes or in their clathrin-coated-vesicles (CCVs), indicating AP-1/sigma 1B-dependent sorting. Synapses contain also more AP-2 CCV, although it is expected that they contain less due to reduced SV recycling. Coat composition of these AP-2 CCVs is altered, and thus, they represent a subpopulation of AP-2 CCVs. Association of calmodulin-dependent protein kinase (CaMK)-II alpha, -delta and casein kinase (CK)-II alpha with the endosome/SV pool is altered, as well as 14-3-3 eta, indicating changes in specific signalling pathways regulating synaptic plasticity. The accumulation of early endosomes and endocytotic AP-2 CCV indicates the regulation of SV recycling via early endosomes by the interdependent regulation of AP-2-mediated endocytosis and AP-1/sigma 1B-mediated SV reformation."],["dc.description.sponsorship","DFG [Schu 802/3-1, 802/3-2]"],["dc.identifier.doi","10.1007/s12035-014-8852-0"],["dc.identifier.isi","000358341600014"],["dc.identifier.pmid","25128028"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36465"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Humana Press Inc"],["dc.relation.issn","1559-1182"],["dc.relation.issn","0893-7648"],["dc.title","AP-1/sigma 1B-Dependent SV Protein Recycling Is Regulated in Early Endosomes and Is Coupled to AP-2 Endocytosis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2005Journal Article [["dc.bibliographiccitation.firstpage","10277"],["dc.bibliographiccitation.issue","11"],["dc.bibliographiccitation.journal","Journal of Biological Chemistry"],["dc.bibliographiccitation.lastpage","10283"],["dc.bibliographiccitation.volume","280"],["dc.contributor.author","Kyttala, A."],["dc.contributor.author","Yliannala, K."],["dc.contributor.author","Schu, Peter Valentin"],["dc.contributor.author","Jalanko, A."],["dc.contributor.author","Luzio, J.

We have recently reported that the lysosomal targeting of CLN3 is facilitated by two targeting motifs: a dileucine-type motif in a cytoplasmic loop domain and an unusual motif in the carboxyl-terminal cytoplasmic tail comprising a methionine and a glycine separated by nine amino acids (Kyttala, A., Ihrke, G., Vesa, J., Schell, M.

The dileucine motif of CLN3 bound both AP-1 and AP-3 in vitro, and expression of mutated CLN3 in AP-1- or AP-3-deficient mouse fibroblasts showed that both adaptor complexes are required for sequential sorting of CLN3 via this motif.

The AP-1 complex mediates protein sorting between the trans-Golgi network and endosomes. Vertebrates express three AP1 sigma 1 subunit isoforms - sigma 1A, sigma 1B and sigma 1C (also known as AP1S1, AP1S2 and AP1S3, respectively). sigma 1B-deficient mice display impaired recycling of synaptic vesicles and lipodystrophy. Here, we show that sortilin is overexpressed in adipose tissue from sigma 1B(-/-) mice, and that its overexpression in wild-type cells is sufficient to suppress adipogenesis. sigma 1B-specific binding of sortilin requires the sortilin DxxD-x12-DSxxxL motif. sigma 1B deficiency does not lead to a block of sortilin transport out of a specific organelle, but the fraction that reaches lysosomes is reduced. Sortilin binds to the receptor DLK1, an inhibitor of adipocyte differentiation, and the overexpression of sortilin prevents DLK1 downregulation, leading to enhanced inhibition of adipogenesis. DLK1 and sortilin expression are not increased in the brain tissue of sigma 1B(-/-) mice, although this is the tissue with the highest expression of sigma 1B and sortilin.

AP-3A appears to mediate trans -Golgi network-to-lysosome and also endosome-to-lysosome protein sorting. AP-1A is thought to be required for both trans -Golgi network-to-endosome transport and endosome-to-trans -Golgi network transport. However, the recent discovery of a role for monomeric GGA (Golgi localized gamma-ear containing, ARF binding protein) adaptor proteins in trans -Golgi network to endosome protein transport has brought into question the long-discussed trans -Golgi network-to-endosome sorting function of AP-1A. Murine cytomegalovirus gp48 contains an unusual di-leucine-based lysosome sorting signal motif and mediates lysosomal sorting of gp48/major histocompatibility complex class I receptor complexes, preventing exposure of major histocompatibility complex class I at the plasma membrane. We analyzed lysosomal sorting of gp48/major histocompatibility complex class I receptor complexes in cell lines deficient for AP-1A, AP-3A and both, to determine their sorting functions.

Although p56 and gamma-synergin bind to both GGA and gamma appendages in vitro, immunofluorescence labeling of nocodazole-treated cells shows that p56 colocalizes with GGAs on TGN46-positive membranes, whereas gamma-synergin colocalizes with AP-1 primarily on a different membrane compartment. Furthermore, in AP-1-deficient cells, p56 remains membrane-associated whereas gamma-synergin becomes cytosolic. Thus, p56 and gamma-synergin show very strong preferences for GGAs and AP-1, respectively, in vivo. However, the GGA and gamma appendages share the same fold as determined by x-ray crystallography, and mutagenesis reveals that the same amino acids contribute to their binding sites.
