Vps10p stability and CPY maturation in WT,
apl2Δ, clc1Δ,
pep12Δ, and vps34Δ strains.
WT/LSY93-2A, apl2Δ/GPY1783-10A,
clc1Δ/LSY93-5B,
pep12Δ/RSY1306, and
vps34Δ/ PHY102 strains were
radiolabeled for 10 min with [35S]methionine and cysteine
directly at 30°C. After a chase for the indicated times (0, 1, and
2 h), aliquots of cells were removed and subjected to
immunoprecipitation with antibodies to Vps10p (A) or CPY (B). The
PEP4-dependent cleavage product is indicated (∗).
