Psychiatry related information on SMY1

 

High impact information on SMY1

  • We have also observed a genetic interaction between SMY1 and two of the late SEC mutations, sec2 and sec4 [1].
  • Unexpectedly, we found that abolition of microtubules by nocodazole does not interfere with the ability of Smy1p to correct the mutant Myo2p defect, nor does it interfere with the ability of Smy1p to localize properly [1].
  • We have previously reported that a defect in Myo2p, a myosin in budding yeast (Saccharomyces cerevisiae), can be partially corrected by overexpression of Smy1p, which is by sequence a kinesin-related protein (Lillie, S.H., and S.S. Brown. 1992. Nature. 356:358- 361) [1].
  • Such a functional link between putative actin- and microtubule-based motors is surprising, so here we have tested the prediction that Smy1p indeed acts as a microtubule-based motor [1].
  • Smy1p, a kinesin-related protein that does not require microtubules [1].
 

Biological context of SMY1

 

Physical interactions of SMY1

  • We now show by two-hybrid analysis that a 69-amino acid region of the Smy1p tail interacts with the globular portion of the Myo2p tail [4].
 

Regulatory relationships of SMY1

  • We propose that Smy1p enhances some aspect of Myo2p function, perhaps delivery or docking of vesicles at the bud tip [4].
