A number of highly regulated gene classes are regulated post-transcriptionally at the level of mRNA stability. and AUF1/AUF1 homodimers as well as HuR/AUF1 heterodimers was observed. Treatment with the MAP kinase activator, anisomycin, which commonly stabilizes ARE-containing mRNAs, caused rapid nuclear to cytoplasmic shuttling of HuR. AUF1 also underwent shuttling, but on a longer time… Continue reading A number of highly regulated gene classes are regulated post-transcriptionally at
