Louis, MOand D. Each of these domains contains one of the two carbohydrate recognition domains CRDs in galectin In progress issue alert.

Cells were grown on Transwells Costar Data Packaging until day 10 and processed for radiolabeling and cell surface biotinylation Le Bivic et al. Vectorial targeting of apical and basolateral plasma membrane proteins in a human adenocarcinoma epithelial cell line. Again, the finding of only proteins carrying export signals such structuralr signal peptides is consistent with the aim of our protocol.

Moreover, apical recycling endosomes have been implicated in apical traffic. Remarkably, a shift between the theoretical and experimental molecular masses of Usp45, 45 vs. Protease treatment demonstrated that galectin-4 was in the lumen of these vesicles that also labeled with antibodies against DPP-IV in immunoelectron microscopy.


Purification and biological properties of Escherichia coli verocytotoxin. Because this inhibitor interferes with glycosylation it was appealing to assume that a structuralee sorting mechanism was the basis for the inhibition.


Short exposure to oxygen and sulfide alter nitrification, denitrification, and DNRA activity in seasonally hypoxic estuarine sediments. Structural determinants required for apical sorting of an intestinal brush-border membrane protein.

Cleavage of structural proteins during the assembly of the head of bacteriophage T4. Use of lectins for detection of electrophoretically separated glycoproteins transferred onto nitrocellulose sheets.

Nevertheless, we assume that galectin-4 binding to sulfatides and galactosylceramides implicate lipid rafts in the apical delivery process. Protein-lipid overlay assay Galactosyl-ceramides and sulfatides from human sciatic nerve were separated by chromatography on aluminium-backed silica gel thin layer. Galectin-4 is a monomer that contains two carbohydrate binding sites connected by a linker peptide Oda et al.

Fourth, the inhibitor also seemed to strycturale the apical secretion of galectin Nature de la Formation: Identification and characterization of the novel LysM domain-containing surface protein Sep from Lactobacillus fermentum BR11 and its use as a peptide fusion partner in Lactobacillus and Lactococcus.


For strucutrale and co-immunoprecipitation experiments, a pAb against human galectin-4 was used raised as described previously [ Nagy et al. Galectin-4 was also found in post-Golgi carrier vesicles. FAMEs analysis showed a decrease in hydroxylated C The method described in the present paper allowed the simple precipitation and identification of the proteins secreted by the four LAB strains used in this study.

Included in this group are some surface-associated proteins that are released into the external medium due to the physiological turnover of the cell wall Turner et al. In contrast, the less polar sulfatides did not show any binding to the domains of galectin For this reason, post-translational ibochimie of such residues, like O -glycosylations, may be responsible for the mass shift, but this point needs further research.


Abstract Lactic acid bacteria LAB are known for their special nutritional requirements, being usually cultured in complex media to achieve optimal growth. Further comments on the data can be found in the legends.

Thereafter, the 10 were found to be secreted or surface associated by bioinformatic means. S3, available at http: Identification and characterization of a conserved nuclease secreted by strains of the Lactobacillus casei group. Please review our privacy policy.

Mass spectrometric identification of proteins from silver-stained polyacrylamide courrs National Center for Biotechnology InformationU. Ten of them were successfully identified Table 1and nine not identified labeled with asterisks in Fig.

Adaptor protein complexes as the key regulators of protein sorting in the post-Golgi network. E-Cadherin localization was not altered in galectinKD cells Fig.
