AtUTr1, a UDP-glucose/UDP-galactose transporter from Arabidopsis thaliana, is located in the endoplasmic reticulum and up-regulated by the unfolded protein response
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2006-04-07)
The folding of glycoproteins in the endoplasmic reticulum (ER) depends on a quality control mechanism mediated by the calnexin/calreticulin cycle. During this process, continuous glucose trimming and UDP-glucose-dependent ...
Characterization of the functional domains of boar acrosin involved in nonenzymatic binding to homologous zona pellucida glycoproteins
(1998)
During the first steps of the gamete interaction, the proacrosin/acrosin system seems to play a crucial role in the secondary binding, holding acrosome-reacted spermatozoa during their passage through the zona pellucida. ...
Tetrahydrohyperforin Inhibits the Proteolytic Processing of Amyloid Precursor Protein and Enhances Its Degradation by Atg5-Dependent Autophagy
(Public Library Science, 2015)
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the accumulation of amyloid-beta (A beta) peptide. We have previously shown that the compound tetrahydrohyperforin (IDN5706) prevents accumulation ...
A Real-time PCR assay for detection of low pneumocystis jirovecii levels
(Frontiers Media, 2022)
Here we report a new real-time PCR assay using SYBR Green which provides higher sensitivity for the specific detection of low levels of Pneumocystis jirovecii. To do so, two primer sets were designed, targeting the family ...
Association of complement C3d receptor 2 genotypes with the acquisition of HIV infection in a trial of recombinant glycoprotein 120 vaccine
(2020)
Objectives:Complement C3d receptor 2 (CR2) is the main receptor for complement protein C3d and plays an important role in adaptive immune responses. CR2 genetic variants are associated with susceptibility to systemic lupus ...
BETA-GLUCOSIDASE FROM PENICILLIUM-PURPUROGENUM - PURIFICATION AND PROPERTIES
(PORTLAND PRESS, 1992-04)
Beta-glucosidade was purified from the culture supernatant of penicillium purpurogenum. The purified enzyme was homogeneous on both nondenaturing and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. The ...

TleA, a Tsh-Like Autotransporter Identified in a Human Enterotoxigenic Escherichia coli Strain
(AMER SOC MICROBIOLOGY, 2015)
Enterotoxigenic Escherichia coli (ETEC), a leading cause of acute diarrhea, colonizes the intestine by means of adhesins. However, 15 to 50% of clinical isolates are negative for known adhesins, making it difficult to ...
Genetic Characterization of Northwestern Colombian Chikungunya Virus Strains from the 2014–2015 Epidemic.
(Estados Unidos: The American Journal of Tropical Medicine and Hygiene , 2016., 2019-09-27)
Chikungunya fever, an acute and often chronic arthralgic disease caused by the mosquito-borne alphavirus,chikungunya virus (CHIKV), spread into the Americas in late 2013. Since then it has caused epidemics in nearly all ...
Expression of multidrug resistance proteins in prostate cancer is related with cell sensitivity to chemotherapeutic drugs
(2009)
BACKGROUND. Multidrug resistance (MDR) proteins have been associated with the lack of chemotherapy response. Expression of these proteins has been described in the prostate, but there is no information about their role in ...
