Programmed death ligand 1 (PD-L1) is critical for the ability of cancer cells to evade attacks by the host immune system. However, the molecular mechanisms controlling PD-L1 expression have not been fully understood. Here, we demonstrate that sorting nexin 6 (SNX6) is a novel regulator of PD-L1 expression. Knockdown of SNX6 in cancer cells significantly decreases PD-L1 protein levels. In contrast, loss of SNX6 does not reduce PD-L1 mRNA levels. Instead, SNX6 interacts with Cullin3, an E3 ubiquit ...[more]
