Dataset Summary
TitleFICD activity and AMPylation remodelling modulate human neurogenesis
DescriptionThe AMPylation is novel protein post-translation modification. In consist of attachment of the adenosine monophosphate onto the serine, threonine or tyrosine amino acid residues of the protein. This process is catalysed by bacterial effectors or in human by protein FICD (also called HYPE) which contain conserved fic domain. In our study we have focused on identification of the unknown AMPylated proteins and their function in human cells (HeLa, A549, SH-SY5Y, iPSCs, NPCs and neurons) and cerebral organoids (COs). For this purpose we designed and synthesized the small molecule N6-propargyl phosphoramidate adenosine (pro-N6pA) which was used for in situ labelling of the AMPylation in cells and COs. Subsequnetly the the propargyl tag was employed for preparation of chemical-proteomic samples which were measured by LC-MS/MS. This approach confirmed the known AMPylation of heat shock protein HSPA5 and found diverse group of novel AMPylation targets. Several cathepsins found as AMPylation targets were further characterized by identification of AMP binding site. Based on our chemical proteomic data we found out that neurons and neuronal like cells contain distinct AMPylatino pattern from other studied cell types. This also suggested the importance of the AMPylation in these cell types which were then studied in cerebral organoids by overexpressing the FICD wt and E234G highly active mutant. This led to the accelerated differentiation of progenitors into the neurons. Overall our approach is suitable for identification of the AMPylated proteins in living cells and led to characterization of FICD function.
