WebSyk is an important protein-tyrosine kinase in immunoreceptor signaling. FcεRI aggregation in mast cells induces tyrosine phosphorylation and increased enzymatic activity of Syk. The two adjacent tyrosines in the Syk activation loop are thought to be important for the propagation of FcεRI signaling.

Web12. jan 2024. · Let us first explain why the anomaly we have just computed corresponds to a one-loop effect. One can introduce a formal loop-counting parameter by rescaling the action as S → 1 λ S. Then in computing Feynman diagrams, the propagators get an extra factor λ while the vertices get an extra 1 λ. Thus every Feynman diagram comes with a … Web26. feb 2024. · In this paper we show that a similar picture holds for generalizations of the SYK model with q-fermion interactions.
