ProteomicsDifferential N-terminal COFRADIc analyses of Ogden fibroblasts
The X-linked lethal Ogden syndrome was the first reported human genetic disorder associated with a mutation in an N-terminal acetyltransferase gene. The affected males harbour a Ser37Pro mutation in the gene encoding hNaa10, the catalytic subunit of NatA, themajor human NAT. In order to understand t...

ProteomicsN-terminal acetylome analysis reveals an expanded substrate profile for the NatC N-terminal acetyltransferase complex in yeast
N-terminal acetylation is a conserved protein modification among eukaryotes, and the yeast Saccharomyces cerevisiae is a valuable model system for studying this modification. The enzymes responsible for the bulk of protein N-terminal acetylation in S. cerevisiae are the N-terminal acetyltransferases...

Proteogenomics is a research field where proteome data is used to improve gene annotation. To achieve this, customized protein databases are constructed to match proteomic data. We perform a proteogenomic analysis using N-terminal COFRADIC data in order to identify novel translational initiation sta...

ProteomicsPositional proteomics reveals differences in N-terminal proteoform stability.
To understand the impact of alternative translation initiation on a proteome, we performed the first large-scale study of protein turnover rates in which we distinguish between N-terminal proteoforms pointing to translation initiation events. Using pulsed SILAC combined with N-terminal COFRADIC we m...

N-terminal proteoforms stem from the same gene but differ at their N-terminus, and most of these are found to be truncated, though some are N-terminally extended caused by ribosomes starting translation from codons in the annotated 5’UTR, and/or carry modified N-termini different from those of the c...

ProteomicsN-terminal acetylome analyses reveals the substrate specificity profile of Naa50 (Nat5) and implicate NATs in influencing initiator Methionine processing
Co-translational N-terminal (Nt-) acetylation of nascent polypeptides is catalyzed by N-terminal acetyltransferases (NATs). The very N-terminal amino acid sequence is the major factor determining whether or not a given protein is Nt-acetylated. In humans, six different NATs, denoted NatA-NatF, are i...

ProteomicsMetabolic regulation of N-terminal acetylation in yeast
N-terminal (Nt) acetylation, catalyzed by N-terminal acetyltransferases (NATs), has emerged as an important co-translational modification in eukaryotes, and involves the transfer of the acetyl moiety from acetyl-CoA (Ac-CoA) to the α-amino group of a nascent polypeptide. Here, we report the first gl...

ProteomicsAn organellar Nα-acetyltransferase Naa60 acetylates cytosolic N-termini of transmembrane proteins and maintains Golgi integrity
N-terminal acetylation is a major and vital protein modification catalysed by N-terminal acetyltransferases (NATs). NatF or Nα-acetyltransferase 60 (Naa60) was recently identified as a NAT in higher eukaryotes. Here, we found that Naa60 differs from all other known NATs by its Golgi localization. A ...
