Recent Findings in the Posttranslational Modifications of PD-L1

Figure 1

The mechanism of PD-L1 PTMs. Multiple factors are involved in the PTMs of PD-L1 at protein level. The signals implicating the PTMs (N-glycosylation, phosphorylation, polyubiquitination, and palmitoylation) of PD-L1 are presented.
