Abstract: Fucose sugars are expressed on mammalian cell L-Fucose (Fuc) is a 6-deoxyhexose expressed at the termini of glycan membranes as part of glycoconjugates and mediates essential chains that decorate cell surface proteins and lipids.1 The fucose physiological processes. The aberrant expression of fucosylated residues on glycoconjugates are essential mediators of physiological glycans has been linked to pathologies such as cancer, inflammation, processes. For example, the fucose moiety in the tetrasaccharide infection, and genetic disorders. Tools to modulate fucose expression sialyl Lewisx (sLex) expressed on leukocytes is recognized by selectin on living cells are needed to elucidate the biological role of fucose receptors that regulate leukocyte recruitment and extravasation.

												  An Atpase Domain Common to Prokaryotic Cell Cycle ProteinsProc. Natl. Acad. Sci. USA Vol. 89, pp. 7290-7294, August 1992 Biochemistry An ATPase domain common to prokaryotic cell cycle proteins, sugar kinases, actin, and hsp7O heat shock proteins (structural comparison/property pattern/remote homology) PEER BORK, CHRIS SANDER, AND ALFONSO VALENCIA European Molecular Biology Laboratory, D-6900 Heidelberg, Federal Republic of Germany Communicated by Russell F. Doolittle, March 6, 1992 ABSTRACT The functionally diverse actin, hexokinase, and hsp7O protein families have in common an ATPase domain of known three-dimensional structure. Optimal superposition ofthe three structures and alignment ofmany sequences in each of the three families has revealed a set of common conserved residues, distributed in five sequence motifs, which are in- volved in ATP binding and in a putative interdomain hinge. From the multiple sequence aliment in these motifs a pattern of amino acid properties required at each position is defined. The discriminatory power of the pattern is in part due to the use of several known three-dimensional structures and many sequences and in part to the "property" method ofgeneralizing from observed amino acid frequencies to amino acid fitness at each sequence position. A sequence data base search with the pattern significantly matches sugar kinases, such as fuco-, glucono-, xylulo-, ribulo-, and glycerokinase, as well as the prokaryotic cell cycle proteins MreB, FtsA, and StbA. These are predicted to have subdomains with the same tertiary structure as the ATPase subdomains Ia and Ha of hexokinase, actin, and Hsc7O, a very similar ATP binding pocket, and the capacity for interdomain hinge motion accompanying func- tional state changes.

Abstract Eukaryotes possess eight highly conserved Lsm (like Sm) proteins that assemble into circular, heteroheptameric complexes, bind RNA, and direct a diverse range of biological processes. Among the many essential functions of Lsm proteins, the cytoplasmic Lsm1-7 complex initiates mRNA decay, while the nuclear Lsm2-8 complex acts as a chaperone for U6 spliceosomal RNA. It has been unclear how these complexes perform their distinct functions while differing by only one out of seven subunits. Here, we elucidate the molecular basis for Lsm-RNA recognition and present four high-resolution structures of Lsm complexes bound to RNAs. The structures of Lsm2-8 bound to RNA identify the unique 2′,3′ cyclic phosphate end of U6 as a prime determinant of specificity. In contrast, the Lsm1-7 complex strongly discriminates against cyclic phosphates and tightly binds to oligouridylate tracts with terminal purines.

The genetic contribution to human T2D and related metabolic disorders is evident, and mostly follows polygenic inheritance. The TALLYHO/ JngJ (TH) mice are a polygenic model for T2D characterized by obesity, hyperinsulinemia, impaired glucose uptake and tolerance, hyperlipidemia, and hyperglycemia.

												  The Role of the Salvage Pathway in Nucleotide Sugar BiosynthesisTHE ROLE OF THE SALVAGE PATHWAY IN NUCLEOTIDE SUGAR BIOSYNTHESIS: IDENTIFICATION OF SUGAR KINASES AND NDP-SUGAR PYROPHOSPHORYLASES by TING YANG (Under the Direction of Maor Bar-Peled) ABSTRACT The synthesis of polysaccharides, glycoproteins, glycolipids, glycosylated secondary metabolites and hormones requires a large number of glycosyltransferases and a constant supply of nucleotide sugars. In plants, photosynthesis and the NDP-sugar inter-conversion pathway are the major entry points to form NDP-sugars. In addition to these pathways is the salvage pathway, a less understood metabolism that provides the flux of NDP-sugars. This latter pathway involves the hydrolysis of glycans to free sugars, sugar transport, sugar phosphorylation and nucleotidylation. The balance between glycan synthesis and recycling as well as its regulation at various plant developmental stages remains elusive as many of the molecular components are unknown. To understand how the salvage pathway contributes to the sugar flux and cell wall biosynthesis, my research focused on the functional identification of salvage pathway sugar kinases and NDP-sugar pyrophosphorylases. This research led to the first identification and enzymatic characterization of galacturonic acid kinase (GalA kinase), galactokinase (GalK), a broad UDP-sugar pyrophosphorylase (sloppy), two promiscuous UDP-GlcNAc pyrophosphorylases (GlcNAc-1-P uridylyltransferases), as well as UDP-sugar pyrophosphorylase paralogs from Trypanosoma cruzi and Leishmania major. To evaluate the salvage pathway in plant biology, we further investigated a sugar kinase mutant: galacturonic acid kinase mutant (galak) and determined if and how galak KO mutant affects the synthesis of glycans in Arabidopsis. Feeding galacturonic acid to the seedlings exhibited a 40-fold accumulation of free GalA in galak mutant, while the wild type (WT) plant readily metabolizes the fed-sugar.

Sm-like proteins contain the Sm sequence motif, which consists of 2 regions separated by a linker of variable length that folds as a loop. The Sm-like proteins are thought to form a stable heteromer present in tri-snRNP particles, which are important for pre-mRNA splicing.Sm-like proteins were identified in a variety of organisms based on sequence homology with the Sm protein family (see SNRPD2; MIM 601061).

We identify large numbers of quantitative genetic interactions that inform about the roles that specific genes play to help Pol a,Pold, and Pol e function. fitness analyses Surprisingly, the overlap between the genetic networks affecting the three DNA polymerases does not (QFA) represent the majority of the genetic interactions identified. Instead our data support a model for division of Saccharomyces labor between the different DNA polymerases during DNA replication. For example, our genetic interaction cerevisiae data are consistent with biochemical data showing that Pol e is more important to the Pre-Loading complex than either Pol a or Pol d.

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
