The siglecs (sialic acid-binding Ig-like lectins) are a distinct subset of the Ig superfamily with adhesion-molecule-like structure. We describe here a novel member of the siglec protein family that shares a similar structure including five Ig-like domains, a transmembrane domain, and a cytoplasmic tail containing two ITIM-signaling motifs. Siglec10 was identified through database mining of an asthmatic eosinophil EST library. Using the Stanford G3 radiation hybrid panel we were able to localize the genomic sequence of siglec-10 within the cluster of genes on chromosome 19q13.

There is much evidence to indicate that cholesterol forms lateral membranemicrodomains (rafts), and to suggest their important role in cellular signaling. However, no probe has been produced to analyze cholesterol behavior, especially cholesterol movement in rafts, in real time. To obtain a potent tool for analyzing cholesterol dynamics in rafts, we prepared and characterized several truncated fragments of h-toxin (perfringolysin O), a cholesterol-binding cytolysin, whose chemicallymodified formhas been recently shown to bind selectively to rafts. ...

The dermal glands of frogs produce antimicrobial peptides that protect the skin against noxious microorganisms and assist in wound repair. The sequences of these peptides are very dissimilar, both within and between species, so that the 5000 living anuran frogs may produce
100 000 different antimicrobial peptides.

SOCS3 is a negative regulator of cytokine signalling that inhibits Janus kinase-signal transduction and activator of transcription (JAK-STAT) mediated signal tranduction by binding to phosphorylated tyrosine residues on intracellular subunits of various cytokine receptors, as well as possibly the JAK proteins.

Calmodulin (CaM) is a cytosolic Ca 2+ signal-transducing protein that binds and activates many different cellular enzymes with physiological rele-vance, including the nitric oxide synthase (NOS) isozymes. CaM consists of two globular domains joined by a central linker; each domain contains an EF hand pair.

Structural analysis of protein tyrosine phosphatases (PTPs) has expanded considerably in the last several years, producing more than 200 structures in this class of enzymes (from 35 different proteins and their complexes with ligands). The small–medium size of the catalytic domain of280 resi-dues plus a very compact fold makes it amenable to cloning and over-expression in bacterial systems thus facilitating crystallographic analysis.

The unique ability of mammals to detect and discriminate between thou-sands of different odorant molecules is governed by the diverse array of olfactory receptors expressed by olfactory sensory neurons in the nasal epithelium. Olfactory receptors consist of seven transmembrane domain G protein-coupled receptors and comprise the largest gene superfamily in the mammalian genome.

Fas-associated protein with death domain (FADD) is an essential adaptor protein in death receptor-mediated signal transduction. During apoptotic signaling, FADD functions in the cytoplasm, where it couples activated receptors with initiator caspase-8. However, in resting cells, FADD is pre-dominantly stored in the nucleus. In this study, we examined the modalities of FADD intracellular trafficking.

Frataxin is a highly conserved nuclear-encoded mitochondrial protein whose deficiency is the primary cause of Friedreich’s ataxia, an autosomal recessive neurodegenerative disease. The frataxin structure comprises a well-characterized globular domain that is present in all species and is pre-ceded in eukaryotes by a non-conserved N-terminal tail that contains the mitochondrial import signal.

The copines are a family of C2- and von Willebrand factor A-domain-con-taining proteins that have been proposed to respond to increases in intra-cellular calcium by translocating to the plasma membrane. The copines have been reported to interact with a range of cell signalling and cytoskele-tal proteins, which may therefore be targeted to the membrane following increases in cellular calcium.

Escherichia coliphosphotransacetylase (Pta) catalyzes the reversible inter-conversion of acetyl-CoA and acetyl phosphate. Both compounds are critical in E. colimetabolism, and acetyl phosphate is also involved in the regulation of certain signal transduction pathways. Along with acetate kinase, Pta plays an important role in acetate production when E.
