Deletion of the N-myristoylprotein SIP2 results in reduced resistance to nutrient deprivation and a 60% shorter lifespan accompanied by signs of accelerated aging such as loss of silencing from telomeres and mating loci, redistribution of Sir3 to the nucleolus, progressive sterility, nucleolar fragmentation and enlargement, and accumulation of extrachromosomal rDNA [10921902].
SIP2 deletion increases replicative lifespan by 20% in the alpha strain [19030232].
SIP1 null mutation causes increase in the intracellular ATP and NAD+ levels in both young cells (generation 0-1) and older cells (generation 4), but the increase is greater in older cells [10921902].
Mean: -60 to +20
