AhR-ROR-γt complex is a therapeutic target for MAP4K3/GLKIL-17A subpopulation of systemic lupus erythematosus.

The cytokine IL-17A plays critical roles in the pathogenesis of autoimmune diseases. The frequencies of MAP kinase kinase kinase kinase 3 [also named germinal center kinase-like kinase (GLK)]-overexpressing T cells are correlated with disease severity of systemic lupus erythematosus (SLE). T-cell-specific GLK-transgenic mice develop spontaneous autoimmune responses through IL-17A.

The cysteine residues at the C-terminal tail of Bamboo mosaic virus triple gene block protein 2 are critical for efficient plasmodesmata localization of protein 1 in the same block.

The movement of some plant viruses are accomplished by three proteins encoded by a triple gene block (TGB). The second protein (TGBp2) in the block is a transmembrane protein. This study was aimed to unravel the mechanism underlying the relatively inefficient cell-to-cell movement of Bamboo mosaic virus (BaMV) caused by amino acid substitutions for the three Cys residues, Cys-109, Cys-112 and Cys-119, at the C-terminal tail of TGBp2.

The stable association of virion with the triple-gene-block protein 3-based complex of Bamboo mosaic virus.

The triple-gene-block protein 3 (TGBp3) of Bamboo mosaic virus (BaMV) is an integral endoplasmic reticulum (ER) membrane protein which is assumed to form a membrane complex to deliver the virus intracellularly. However, the virus entity that is delivered to plasmodesmata (PD) and its association with TGBp3-based complexes are not known. Results from chemical extraction and partial proteolysis of TGBp3 in membrane vesicles revealed that TGBp3 has a right-side-out membrane topology; i.

The two conserved cysteine residues of the triple gene block protein 2 are critical for both cell-to-cell and systemic movement of Bamboo mosaic virus.

The triple gene block protein 2 (TGBp2) of Bamboo mosaic virus (BaMV) is a transmembrane protein which is known to be required for the cell-to-cell movement of potexviruses. This protein has two conserved Cys residues, Cys-109 and Cys-112, at its C-terminal tail, which is supposed to be exposed on the outer surface of the endoplasmic reticulum (ER) membrane and ER-derived granular vesicles. In this study, we investigated the importance of these two Cys residues on the cell-to-cell and systemic movement of BaMV.

Characterization of the RNA-binding properties of the triple-gene-block protein 2 of Bamboo mosaic virus.

The triple-gene-block protein 2 (TGBp2) of Bamboo mosaic virus (BaMV) is a transmembrane protein which was proposed to be involved in viral RNA binding during virus transport. Here, we report on the RNA-binding properties of TGBp2. Using tyrosine fluorescence spectroscopy and UV-crosslinking assays, the TGBp2 solubilized with Triton X-100 was found to interact with viral RNA in a non-specific manner.

Topological properties of the triple gene block protein 2 of Bamboo mosaic virus.

The triple gene block protein 2 (TGBp2) of Bamboo mosaic virus (BaMV) has been proposed to be a transmembrane protein; however, its features remain unclear. Here, we used biochemical approaches to determine its topological properties. Our data reveal that TGBp2 is mainly associated with the endoplasmic reticulum membrane.
