Function

[FYB_HUMAN] Acts as an adapter protein of the FYN and LCP2 signaling cascades in T-cells. Modulates the expression of interleukin-2 (IL-2). Involved in platelet activation. Prevents the degradation of SKAP1 and SKAP2. May play a role in linking T-cell signaling to remodeling of the actin cytoskeleton.[1] [2] [3]

Publication Abstract from PubMed

Oxidation-induced conformational changes in proteins provide a powerful mechanism to sense the redox state of a living cell. In contrast to the unspecific and often irreversible oxidation of intracellular proteins during severe oxidative stress, regulatory redox events need to have specific and transient effects on cellular targets. Here we present evidence for the reversible formation of a vicinal disulfide bond in a prototypic protein interaction domain. NMR spectroscopy was used to determine the structure of the N-terminal hSH3 domain (hSH3N) of the immune cell protein ADAP (adhesion and degranulation promoting adapter protein) in the reduced and oxidized states. An eight-membered ring formed upon oxidation of two neighboring cysteines leads to significant changes in the variable arginine-threonine (RT) loop of the hSH3N domain and alters the helix-sheet packing of the domain. The redox potential for this structural transition is -228 mV at pH 7.4. This is compatible with a role of the cysteinylcysteine moiety in redox signaling during T cell activation.
