Introduction

In the field of proteomics, post-translational modification (PTM) plays a crucial role in understanding the complexity of protein function and regulation. PTMs, such as phosphorylation, ubiquitination, and acetylation, can significantly alter the activity, localization, and stability of proteins. However, identifying PTM sites in proteomic experiments can be a challenging task due to the complexity of mass spectrometry (MS) data. Scaffold PTM, a computational tool, has been developed to automate PTM site assignment in proteomic experiments, providing researchers with an objective measure of the confidence of PTM site identification.

What is Scaffold PTM?

Scaffold PTM is a computational tool designed to analyze MS/MS spectral output and assign PTM sites with high accuracy. It uses a combination of algorithms and statistical methods to identify PTM sites, taking into account the complexity of MS data. The tool is particularly useful for researchers who want to identify PTM sites in large-scale proteomic experiments, such as those involving phosphoproteomics or ubiquitinomics.

How Does Scaffold PTM Work?

Scaffold PTM works by analyzing MS/MS spectral output, which is generated by mass spectrometers during proteomic experiments. The tool uses a combination of algorithms and statistical methods to identify PTM sites, including:

Peptide identification: Scaffold PTM identifies peptides from MS/MS spectral output using algorithms such as Mascot or Sequest.
PTM site assignment: The tool assigns PTM sites to identified peptides using statistical methods, such as probability-based scoring.
Confidence scoring: Scaffold PTM provides a confidence score for each PTM site assignment, indicating the likelihood of the site being correct.
