We report the cloning of a Leishmania chagasi antigen gene and an evaluation of leishmaniasis patient antibody responses to the recombinant protein, rK39. rK39 contains a 39-amino acid repeat that is part of a 230-kDa protein predominant in L. chagasi tissue amastigotes. Sequence analyses showed this protein, LcKin, to be related to the kinesin superfamily of motor proteins. Southern blot analy...

Weighted distributions can be used to fit various forms of resource selection probability functions (RSPF) under the useversus-available study design (Lele and Keim 2006). Although valid, the numerical maximization procedure used by Lele and Keim (2006) is unstable because of the inherent roughness of the Monte Carlo likelihood function. We used a combination of the methods of partial likelihoo...

The identification, isolation and subsequent cloning of effective disease resistance genes for their use to enhance the protection level against various groups of pathogens in plants is an important aspect of crop improvement. Disease resistance genes (R-genes) have been characterized and cloned from many plant species. The resistance gene analogs (RGAs) are putative or tentative disease resist...

The apicomplexan parasite Toxoplasma gondii, the etiologic agent of toxoplasmosis, is estimated to infect 10-80% of different human populations. T. gondii encodes a large pentafunctional polypeptide known as the AROM complex which catalyzes five reactions in the shikimate pathway, a metabolic pathway required for the biosynthesis of the aromatic amino acids and a promising target for anti-paras...

Transcription factor AP-2 is essential for craniofacial, nervous system, and limb development in the mouse. We report here the cloning and expression pattern analysis of DAP-2, the Drosophila homolog of AP-2 family genes. DAP-2 is expressed in discrete regions of procephalic neuroectoderm, the brain, ventral nerve cord, and maxillary segment during Drosophila embryogenesis, and in the brain, op...

The murine Mac-2 protein is a galactose- and IgE-binding lectin secreted by inflammatory macrophages. We describe here the cloning and characterization of a cDNA representing the human homolog of Mac-2 (hMac-2). The amino acid sequence derived from the hMac-2 cDNA indicates that the protein is evolutionarily highly conserved, with 85% of its amino acid residues being similar to those in the mur...

Maternal mRNA translation is regulated in large part by cytoplasmic polyadenylation. This process, which occurs in both vertebrates and invertebrates, is essential for meiosis and body patterning. In spite of the evolutionary conservation of cytoplasmic polyadenylation, many of the cis elements and trans-acting factors appear to have some species specificity. With the recent isolation and cloni...

Recent advances on the properties of the mycoplasma genome, including size, base composition, replication, extrachromosomal DNA, and transfer of genetic material are briefly reviewed, with emphasis on their phylogenetic implications. The use of cleavage patterns of the mycoplasma genome by restriction endonucleases as "finger-prints" indicating genetic relatedness among strains is discussed. Th...

The completion of the human genome sequence, along with that of many other species, has highlighted the challenge of ascribing specific function to non coding sequences. One prominent function carried out by the non coding fraction of the genome is to regulate gene transcription; however, there are no effective methods to broadly predict cis-regulatory elements from primary DNA sequence. We hav...
