Chemoenzymatic Labeling of Protein C-Termini for Positive Selection of C-Terminal Peptides

بررسی گلیکوزیلاسیون آنتی ژن c-terminal msp1 (c-terminal merozoite surface protein) در پلاسمودیوم فالسیپاروم

مالاریا یکی از بیماری های مهم انگلی در کشورهای گرمسیری دنیا است. پلاسمودیوم فالسیپاروم انگل تک یاخته ای است که تب سه یک بدخیم را ایجاد می کند. آنتی ژن های پلاسمودیوم فالسیپاروم در سطح انگل یا در سطح سلول های آلوده ،کاندیداهای عمده جهت تولید واکسن می باشند، مانند: msp 1 و msp2 . کربوهیدرات های متصل به پروتئین های انگل مالاریا بعنوان اپی توپ های آنتی ژنیک مطرح بوده و بوسیله سیستم ایمنی میزبان تشخ...

Protein Kinase C- Is Required for Efficient Positive Selection

Protein kinase C(PKC ) is critical for TCR-initiated signaling in mature T cells, but initial reports found no requirement for PKC in thymocyte development. Thymocytes and peripheral T cells utilize many of the same signaling components and, given the significant role of PKC in peripheral T cells, it was surprising that it was not involved at all in TCR signaling in thymocytes. We decided to re...

The Recent De Novo Origin of Protein C-Termini

Protein-coding sequences can arise either from duplication and divergence of existing sequences, or de novo from noncoding DNA. Unfortunately, recently evolved de novo genes can be hard to distinguish from false positives, making their study difficult. Here, we study a more tractable version of the process of conversion of noncoding sequence into coding: the co-option of short segments of nonco...

Predictive ability of C-reactive protein for stroke

Solid-phase chemoenzymatic synthesis of C-sialosides.

The chemoenzymatic regioselective acylation of Neu5Ac followed by SmI2-mediated C-glycosylation on a solid support is described for five C-glycosides. This method should facilitate the construction of combinatorial libraries of inhibitors of neuraminidase activity and hemagglutinin interaction as potential antiviral agents.
