...Tae K. Kim; Janet Curran; Albert Mulenga This study demonstrates that Amblyomma americanum ( Aam ) constitutively and ubiquitously expresses the long (L) and short (S) putative acidic chitinases (Ach) that are distinguished by a 210 base pair (bp) deletion in Aam Ach-S. Full-length Aam Ach-L...

..., the complement activation pathway and blood coagulation. In this study, we show that Amblyomma americanum ( Aam ) serpin (S) 6 is putatively injected into the host during tick feeding, in that the antibody to recombinant (r) AamS6 specifically reacted with the expected ∼43/45 kDa AamS6 protein band on western...

... of three Amblyomma americanum (L.) ( Aam ) proteins that show amino-terminal sequence and secondary structure similarity to the IGFBP superfamily. The three molecules here provisionally identified as Aam IGFBP-rP1 and short (S) and long (L) Aam IGFBP-rP6 are expressed in multiple tick organs...

... plasma membranes. We previously discovered an Amblyomma americanum tick ( Aam ) Oatp cDNA among genes that were upregulated or induced in ticks that were stimulated to start feeding. In this study, we have characterized a 2860 bp full-length cDNA that encode a 724 amino acid putative protein...

...Albert Mulenga; Rabuesak Khumthong; Maria A. Blandon SUMMARY Serine proteinase inhibitors (serpins) are a family of structurally similar but functionally diverse proteins that regulate several important proteolytic cascades in most branches of life. We have characterized 17 Amblyomma americanum...
