EAST is an EGF receptor substrate that binds actin (as does the EGF receptor its self - see below).  The name comes from EGFR-Associated protein with SH3 and TAM domains, and is not to be confused with another protein called EAST that is a nucleoskeletal protein (part of the nuclear matrix) (see Lasky, 2000). As the name implies EAST binds the EGF receptor directly (Lohi et al, 1998).  The N-terminus of EAST is responsible for binding actin (Lohi & Lehto, 1998).  EAST also binds Eps15 another ABP (see below). EAST is enriched at focal adhesions and in some cells (MDCK) at cell-cell contacts (Lohi & Lehto, 1998).
