Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Ex Input:
Ataxin-3 (AT3) is the protein that triggers the inherited neurodegenerative disorder spinocerebellar ataxia type 3 when its polyglutamine (polyQ) stretch close to the C-terminus exceeds a critical length. AT3 consists of the N-terminal globular Josephin domain (JD) and the C-terminal disordered one. It cleaves isopeptide bonds between ubiquitin monomers, an event involved in protein quality control mechanisms. AT3 has been implicated in the pathway that sorts aggregated protein to aggresomes via microtubules, in which dynein and histone deacetylase 6 (HDAC6) also seem to be involved. By taking advantage of small angle X-ray scattering (SAXS) and surface plasmon resonance (SPR), we have investigated the interaction of AT3 with tubulin and HDAC6. Based on SAXS results, the AT3 oligomer, consisting of 6-7 subunits, tightly binds to the tubulin hexameric oligomer in a "parallel" fashion. By SPR analysis we have demonstrated that AT3 binds to tubulin dimer with a 50nM affinity. Binding fits with a Langmuir 1:1 model and involves a single binding interface. Nevertheless, the interaction surface consists of three distinct, discontinuous tubulin-binding regions (TBR), one located in the JD, and the two others in the disordered domain, upstream and downstream of the polyQ stretch. In the absence of any of the three TBRs, the affinity is drastically reduced. By SPR we have also provided the first evidence of direct binding of AT3 to HDAC6, with affinity in the range 0.1-1M. These results shed light on the interactions among the components of the transport machinery that sorts aggregate protein to the aggresome, and pave the way to in vivo studies aimed at further clarifying their roles.

Ex Output:
Which is the protein implicated in Spinocerebellar ataxia type 3?


Ex Input:
Coming off their divisional road win over the Dolphins, the Jets flew to Ralph Wilson Stadium for a Week 4 AFC East duel with the throwback-clad Buffalo Bills. New York scored in the first quarter as running back LaDainian Tomlinson got a 1-yard touchdown run. The Jets added onto their lead in the second quarter with a 19-yard field goal from kicker Nick Folk, followed by quarterback Mark Sanchez completing a 41-yard touchdown pass to wide receiver Braylon Edwards. The Bills closed out the half with quarterback Ryan Fitzpatrick finding tight end David Martin on a 4-yard touchdown pass. New York pulled away in the third quarter as tight end Dustin Keller caught a 3-yard touchdown pass from wide receiver/quarterback Brad Smith, followed by his 2-yard touchdown reception thrown by Sanchez. Afterwards, Tomlinson's 26-yard touchdown run effectively secured the victory. Buffalo closed out the game in the fourth quarter as Fitzpatrick threw a touchdown pass to wide receiver Steve Johnson.

Ex Output:
Which player scored multiple touchdowns?
