Anti-Human IRGQ Polyclonal Antibody

Immunity-related GTPase family Q protein (IRGQ) is a ~62 kDa protein. Autophagy receptor that specifically promotes clearance of misfolded MHC class I molecules by targeting them to the lysosome for degradation. Acts as a molecular adapter that specifically recognizes and binds (1) misfolded MHC class I molecules following their ubiquitination, as well as (2) autophagy-related proteins, promoting the recruitment of misfolded MHC class I molecules to autophagy machinery for degradation. Degradation of misfolded MHC class I molecules is essential to prevent accumulation of defective MHC class I complexes at the surface of CD8(+) T-cells and prevent a stronger T-cell-mediated response. In contrast to other members of the family, does not show GTPase activity.
