Nexus between Pin1 and inositol pyrophosphate (IPP) status. (A) Pin1 is essential in the absence of IP8. S. pombe strains with genotypes as specified were spot-tested for growth on YES agar at the indicated temperatures. (B) Lethality of asp1-H397A aps1Δ is rescued by pin1Δ. Cells with the indicated genotypes were grown in liquid culture in YES medium at 30°C and assayed for Pho1 acid phosphatase activity.
