Objective(s): Nanobodies, the single domain antigen binding fragments of heavy chain-only antibodies occurring naturally in camelid sera, are the smallest intact antigen binding entities. Their minimal size assists in reaching otherwise largely inaccessible regions of antigens. However, their camelid origin raises a possible concern of immunogenicity when used for human therapy. Humanization is...

Introduction: Mutations in the BRCA1 gene are major risk factors for breast and ovarian cancers. However, the relationship between some BRCA1 mutations and cancer risk remains largely unknown. Cancer risk predictions could be improved by evaluation of the impairment degree in the BRCA1 functions due to a specific mutation. This study aimed to assess the functional effect of a novel variant (Glu...

The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...

Quorum sensing controls the luminescence of Vibrio fischeri through the transcriptional activator LuxR and the specific autoinducer signal produced by luxI. Amino acid sequences of these two genes were analyzed using bioinformatics tools. LuxI consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by SSpro8. LuxI belongs to the autoinducer synthetase fa...
