Post-transcriptional mechanisms in synaptic plasticity and memory consolidation: Role of mRNA stability (A06)

Subject Area Molecular Biology and Physiology of Neurons and Glial Cells
Term since 2013
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 221828878
 
In the previous funding period, we established that the RNA-binding protein Gadd45a is essential for the consolidation of hippocampus-dependent aversive memory in mouse. RNA-seq analyses of hippocampal tissue revealed that Gadd45a regulates the stability of mRNAs encoding proteins, which are centrally involved in synaptic plasticity and memory processes. In the next funding period we will identify new protein members of Gadd45a containing complexes, the mRNA signatures required for targeting by Gadd45a, and the function of the Ccr4-Not complex (a newly identified Gadd45a partner which is a member of the nonsense-mediated mRNA decay pathway) in mediating the effect of Gadd45a in RNA homeostasis and memory consolidation.
