The mistletoe lectin‐1 (ML‐1) modulates tumor cell apoptosis by triggering signaling cascades through the complex interplay of phosphorylation and O ‐linked N ‐acetylglucosamine ( O ‐GlcNAc) modification in pro‐ and anti‐apoptotic proteins. In particular, ML‐1 is predicted to induce dephosphorylation of Bcl‐2‐family proteins and their alternative O ‐GlcNAc modification at specific, conserved Ser/Thr residues. The sites for phosphorylation and glycosylation were predicted and analyzed using Netphos 2.0 and YinOYang 1.2. The involvement of modified Ser/Thr, and among them the potential Yin Yang sites that may undergo both types of posttranslational modification, is proposed to mediate apoptosis modulation by ML‐1. J.
