Human FYN-binding protein 1,FYB1 ELI

Acts as an adapter protein of the FYN and LCP2 signaling cascades in T-cells (By similarity).

May play a role in linking T-cell signaling to remodeling of the actin cytoskeleton (PubMed:10747096, PubMed:16980616).

Modulates the expression of IL2 (By similarity).

Involved in platelet activation (By similarity).

Prevents the degradation of SKAP1 and SKAP2 (PubMed:15849195).

May be involved in high affinity immunoglobulin epsilon receptor signaling in mast cells (By similarity).
