Potential function for the Huntingtin protein as a scaffold for selective autophagy.
Although dominant gain-of-function triplet repeat expansions in the Huntingtin (HTT) gene are the underlying cause of Huntington disease (HD), understanding the normal functions of nonmutant HTT protein has remained a challenge. We report here findings that suggest that HTT plays a significant role in selective autophagy. Loss of HTT function in Drosophila disrupts starvation-induced autophagy ...
متن کاملThe albumin-binding domain as a scaffold for protein engineering
The albumin-binding domain is a small, three-helical protein domain found in various surface proteins expressed by gram-positive bacteria. Albumin binding is important in bacterial pathogenesis and several homologous domains have been identified. Such albumin-binding regions have been used for protein purification or immobilization. Moreover, improvement of the pharmacokinetics, through the non...
متن کاملOptimal colocalization of TCR and CD8 as a novel mechanism for the control of functional avidity.
The improved efficacy of high avidity CTL for clearance of virus has been well-documented. Thus, elucidation of the mechanisms that confer the increased sensitivity to peptide ligand demonstrated by high avidity CTL is critical. Using CTL lines of high and low avidity generated from a TCR transgenic mouse, we have found that functional avidity can be controlled by the expression of CD8alphaalph...
متن کاملMAGI-2 scaffold protein is critical for kidney barrier function.
MAGUK Inverted 2 (MAGI-2) is a PTEN-interacting scaffold protein implicated in cancer on the basis of rare, recurrent genomic translocations and deletions in various tumors. In the renal glomerulus, MAGI-2 is exclusively expressed in podocytes, specialized cells forming part of the glomerular filter, where it interacts with the slit diaphragm protein nephrin. To further explore MAGI-2 function,...
متن کاملChaperonins as protein-folding machines
The Escherichia coli chaperone GroEL epitomizes the group of chaperone proteins termed as chaperonins. The wealth of structural and functional information available for GroEL, and its accessory protein, the co-chaperonin GroES, has been of much value in deciphering the role of chaperonins in facilitating the folding of substrate proteins in the cell. The chaperonin machinery has a complex archi...
