The N-terminal SH3 domain encompasses two three-stranded antiparallel β-sheets, one strand crosses the two sheets. This confers a barrel-like structure upon the domain. The first sheet contains the 3 following strands: S1 (<scene name='71/719865/Glu2-ala5/1'>Glu2-Ala5</scene>), S2 (<scene name='71/719865/Ile24-lys26/1'>Ile24-Lys26</scene>) and S6 (<scene name='71/719865/Ile53-met55/1'>Ile53-Met55</scene>). The second sheet contains the strands S3 (<scene name='71/719865/Val27-asn29/1'>Val27-Asn29</scene>), S4 (<scene name='71/719865/Trp36-leu41/1'>Trp36-Leu41</scene>) and S5 (<scene name='71/719865/Asp45-ile48/1'>Asp45-Ile48</scene>). The structure of this SH3 domain is stabilized by a high number of hydrophobic residues, which form the centre of the protein.<ref name="a"/> | The N-terminal SH3 domain encompasses two three-stranded antiparallel β-sheets, one strand crosses the two sheets.
