SH2 domain-containing protein 1B, EWS/FLI1-activated transcript 2, EAT-2, SH2D1B, EAT2
By binding phosphotyrosines through its free SRC (MIM 190090) homology-2 (SH2) domain, EAT2 regulates signal transduction through receptors expressed on the surface of antigen-presenting cells (Morra et al., 2001 [PubMed 11689425]).
