1 What I wanted to do this summer
Evaluate inducible inactivation system designed to regulate mitochondrial gene expression Examine unintended consequences of TAP-tagging What I really did this summer

2

3 Targets for protein engineering

4 Pilot studies = no TAP-tag FY631
MAT(A) his4-917, lys2-173R2, leu21, ura3-52, trp163 = SPT3-TAP = SPT7-TAP = SPT10-TAP FY2305 MAT(A) his3200, lys2-128, leu21, ura3-52, trp163

5 SPT10: most affected genes, pt 1
higher - TAP HIS3 as expected

6 SPT10: most affected genes, pt 1
higher - TAP LYS2 No TAP lys2-173R2 vs +TAP lys2-128

7 Also in SPT3-TAP and SPT7-TAP
SPT10: most affected genes, pt 1 higher - TAP OLI1 again! F0-ATP synthase subunit 9 encoded on the mitochondrial genome Ask: OligomycinR? Also in SPT3-TAP and SPT7-TAP

8 SPT10: most affected genes, pt 1
higher - TAP mitochondrial genes

9 SPT10: most affected genes, pt 2
higher + TAP SPT10 Increased expression of SPT10-TAP vs SPT10

10 SPT10: most affected genes, pt 2
higher + TAP PHO5 and PHO11

11 Also in SPT3-TAP and SPT7-TAP
SPT10: most affected genes, pt 2 higher + TAP ADH2 (alcohol dehydrogenase) and ADY2 (Acetate transporter required for normal sporulation; phosphorylated in mitochondria) Also in SPT3-TAP and SPT7-TAP
