When TCR are stimulated, the membrane protein called p36-38 is phosphorylated in the T cells. Then, the phosphorylated tyrosines bind the SH2 domains of Grb2 whereas the SH3 domains are bound to Vav proteins. These interactions allow the T cell proliferation, the calcium flux in these cells and the MAP kinase activation.<ref name="A"/>

Grb2 is an intermediate protein and recruits signalling molecules to form complexes. These signalling complexes cause cellular responses like cellular proliferation or invasion which can have an impact in cancer. Grb2 can also occur in many other stages of the cancer progression : it can lead to tumorigenesis.<ref>DOI:10.1517/14728222.12.8.1021</ref> Moreover, the phosphorylation of the 160 tyrosine on Grb2 has been observed in many human cancers such as prostate, colon or breast cancers and the switch between the dimeric and monomeric conformations regulates the cancer progression.<ref name="anaïs">PMID: 26234419</ref>
