SUMOylation Analysis Service

SUMOylation, a post-translational modification, involves the covalent binding of a small ubiquitin-like modifier (SUMO) to proteins. For comprehensive SUMOylation analysis services, turn to Creative Proteomics, where we excel in the identification, quantification, and characterization of protein SUMOylation modifications. These services promise valuable insights into your protein research initiatives.

What is SUMOylation

In the realm of molecular biology, SUMO proteins, classified as small ubiquitin-like modifiers, constitute a family of petite proteins resembling ubiquitin and are acknowledged as members of the ubiquitin-like protein family. SUMOylation follows an enzymatic cascade akin to that found in ubiquitination. Unlike ubiquitin, however, SUMO does not serve as a marker for proteins slated for degradation. The maturation of SUMO involves the removal of the last four amino acids from the C-terminus, facilitating the creation of an isopeptide bond between the C-terminal glycine residue of SUMO and an acceptor lysine on the target protein.

SUMO proteins undergo covalent attachment or detachment from other cellular proteins through a process known as SUMOylation. While SUMOylation shares similarities with ubiquitination, its functions are distinct. While ubiquitination primarily orchestrates the enzymatic degradation of target molecules, SUMOylation takes charge of localizing and functionally regulating target molecules. This includes aspects such as protein interactions, nucleus-cytoplasmic transport, signal transduction, protein localization, transcriptional regulation, protein stability, and counteracting the effects of ubiquitination.

Applications of SUMOylation Analysis

In addition, it also has many applications such as immune response, neurodegenerative diseases, cell cycle regulation and transcriptional regulation, etc.

Our Service

Creative Proteomics has advanced protein detection technologies and can provide customized services to researchers and scientists to help them reveal the complexity of PTM using powerful mass spectrometry technologies.

• Sample Preparation
  Proper extraction and preparation of proteins from biological samples to ensure preservation of SUMOylated proteins.
• SUMOylation Enrichment
  Enrichment techniques are employed to isolate SUMOylated proteins or peptides. This step is crucial as SUMOylation modifications are often present in low abundance compared to unmodified proteins.
• Detection
  WB, protein microarrays and LC-MS/MS are powerful tools for the identification and quantification of SUMOylated peptides, and they provide detection information that facilitates a comprehensive analysis of SUMOylation.
• Bioinformatics Analysis
  Advanced bioinformatics tools are used to analyze data, identify SUMOylated peptides, and map these modifications to protein sequences.
• Result Delivery
  After professional data analysis, we deliver results quickly and consistently.

Creative Proteomics brings a wealth of experience to the field of protein research. Our comprehensive services and products cover the entire spectrum of utilizing suitable and efficient gateways.
