Claim: TSG101 (Tumor susceptibility gene 201) recognises short linear motif : P(T/S)AP via the UEV protein domain of the VPS23/TSG101 subunit and the structure is primarily composed of four long, parallel helical hairpins, each corresponding to a different subunit.
Evidence: The structure is primarily composed of three long, parallel helical hairpins, each corresponding to a different subunit.
