- ERADication of EDEM1 occurs by selective autophagy and requires deglycosylation by cytoplasmic peptide N-glycanase.
- Park S1, Jang I, Zuber C, Lee Y, Cho JW, Matsuo I, Ito Y, Roth J.Author information 1WCU Program, Department of Integrated OMICS for Biomedical Science, Yonsei University Graduate School, Seoul, 120-749, Korea.AbstractER degradation-enhancing α-mannosidase-like 1 protein (EDEM1) is involved in the routing of misfolded glycoproteins for degradation in the cytoplasm. Previously, we reported that EDEM1 leaves the endoplasmic reticulum via non-COPII vesicles (Zuber et al. in Proc Natl Acad Sci USA 104:4407-4412, 2007) and becomes degraded by basal autophagy (Le Fourn et al. in Cell Mol Life Sci 66:1434-1445, 2009). However, it is unknown which type of autophagy is involved. Likewise, how EDEM1 is targeted to autophagosomes remains elusive. We now show that EDEM1 is degraded by selective autophagy. It colocalizes with the selective autophagy cargo receptors p62/SQSTM1, neighbor of BRCA1 gene 1 (NBR1) and autophagy-linked FYVE (Alfy) protein, and becomes engulfed by autophagic isolation membranes. The interaction with p62/SQSTM1 and NBR1 is required for routing of EDEM1 to autophagosomes since it can be blocked by short inhibitory RNA knockdown of the cargo receptors. Furthermore, p62/SQSTM1 interacts only with deglycosylated EDEM1 that is also ubiquitinated. The deglycosylation of EDEM1 occurs by the cytosolic peptide N-glycanase and is a prerequisite for interaction and aggregate formation with p62/SQSTM1 as demonstrated by the effect of peptide N-glycanase inhibitors on the formation of protein aggregates. Conversely, aggregation of p62/SQSTM1 and EDEM1 occurs independent of cytoplasmic histone deacetylase. These data provide novel insight into the mechanism of autophagic degradation of the ER-associated protein degradation (ERAD) component EDEM1 and disclose hitherto unknown parallels with the clearance of cytoplasmic aggregates of misfolded proteins by selective autophagy.

To define the phenotype associated with a novel inherited disorder of cytosolic endoplasmic reticulum-associated degradation pathway dysfunction, we studied a series of eight patients with deficiency of N-glycanase 1.Methods:Whole-genome, whole-exome, or standard Sanger sequencing techniques were employed. Retrospective chart reviews were performed in order to obtain clinical data.Results:All patients had global developmental delay, a movement disorder, and hypotonia. Other common findings included hypolacrima or alacrima (7/8), elevated liver transaminases (6/7), microcephaly (6/8), diminished reflexes (6/8), hepatocyte cytoplasmic storage material or vacuolization (5/6), and seizures (4/8). The nonsense mutation c.1201A>T (p.R401X) was the most common deleterious allele.Conclusion:NGLY1 deficiency is a novel autosomal recessive disorder of the endoplasmic reticulum-associated degradation pathway associated with neurological dysfunction, abnormal tear production, and liver disease. The majority of patients detected to date carry a specific nonsense mutation that appears to be associated with severe disease. The phenotypic spectrum is likely to enlarge as cases with a broader range of mutations are detected.Genet Med advance online publication 20 March 2014Genetics in Medicine (2014); doi:10.1038/gim.2014.22.

- N-Terminal signal sequence is required for cellular trafficking and hyaluronan-depolymerization of KIAA1199.

Electronic address: yoshida.hiroyuki@kanebocos.co.jp.2Innovative Beauty Science Laboratory, Kanebo Cosmetics Inc., 3-28, 5-chome, Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan.AbstractRecently, we disclosed that KIAA1199-mediated hyaluronan (HA) depolymerization requires an acidic cellular microenvironment (e.g. clathrin-coated vesicles or early endosomes), but no information about the structural basis underlying the cellular targeting and functional modification of KIAA1199 was available. Here, we show that the cleavage of N-terminal 30 amino acids occurs in functionally matured KIAA1199, and the deletion of the N-terminal portion results in altered intracellular trafficking of the molecule and loss of cellular HA depolymerization. These results suggest that the N-terminal portion of KIAA1199 functions as a cleavable signal sequence required for proper KIAA1199 translocation and KIAA1199-mediated HA depolymerization.
