1. Complementary DNAs encoding the mouse GLUT3/brain facilitative glucose transporter have been isolated and sequenced. The predicted amino acid sequence indicates that mouse GLUT3 is composed of 493 amino acids and has 83 and 89% identity and similarity, respectively, to the sequence of human GLUT3. In contrast to human GLUT3 mRNA, which can be readily detected by RNA blotting in all human tissues that have been examined, mouse GLUT3 mRNA was only present at significant levels in brain. In situ hybridization showed differential expression of GLUT3 mRNA in several regions of adult mouse brain. Specific expression was observed in the hippocampus, with GLUT3 mRNA levels being higher in areas CA1 to CA3 than in the dentate gyrus. It was also detected in the Purkinje cell layer of the cerebellum and in the cerebral cortex, with higher expression in the piriform cortex than in other regions of the cortex. Antisera to mouse GLUT3 immunoblotted a series of proteins of 45-50 kDa in mouse brain plasma membranes. These results are consistent with GLUT3 being a neuronal glucose transporter.

2. The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

3. Although the classification of cell types often relies on the identification of cell surface proteins as differentiation markers, flow cytometry requires suitable antibodies and currently permits detection of only up to a dozen differentiation markers in a single measurement. We use multiplexed mass-spectrometric identification of several hundred N-linked glycosylation sites specifically from cell surface-exposed glycoproteins to phenotype cells without antibodies in an unbiased fashion and without a priori knowledge. We apply our cell surface-capturing (CSC) technology, which covalently labels extracellular glycan moieties on live cells, to the detection and relative quantitative comparison of the cell surface N-glycoproteomes of T and B cells, as well as to monitor changes in the abundance of cell surface N-glycoprotein markers during T-cell activation and the controlled differentiation of embryonic stem cells into the neural lineage. A snapshot view of the cell surface N-glycoproteins will enable detection of panels of N-glycoproteins as potential differentiation markers that are currently not accessible by other means.
