With extensive experience in providing Glycoinformatics-assisted Analysis/Prediction Services, CD BioGlyco offers a comprehensive range of professional services including Glycoinformatics-based Structure Modeling Services and Structural and Functional Prediction Services. The details of our glycoinformatics-assisted mucin-type glycosylation site prediction service are as follows.
Our experts first obtain mammalian protein sequence data and glycosylation site information from UniProt, and then build models to predict glycosylation sites based on this information. After obtaining protein sequence data and glycosylation site information, we analyze and organize these data, and use bioinformatics tools to perform sequence comparison, structure prediction, and other operations to identify potential glycosylation sites. Then, the machine learning algorithms or deep learning models are applied to build models for predicting glycosylation sites and evaluate the accuracy and reliability of the models through validation experiments. Our glycosylation site models use a variety of features, including amino acid sequences, secondary structures, relative accessibility of residues, physicochemical properties of amino acids, and features of amino acid sequences, to improve the accuracy of predictions.
We perform detailed calculations and analysis of the frequency of amino acid presence around the glycosylation sites to more accurately estimate the probability of amino acid presence at each position relative to the glycosylation site. Through this, we help you gain insight into the distribution of amino acids at different positions in the protein structure, which provide an important reference for further studies of protein function and structure.

Results: The researchers used support vector machines (SVMs) to predict glycosylation sites of mucins and found that glycosylation sites are usually aggregated in the sequence while other sites are dispersed in the sequence. Therefore, they developed two types of SVMs to predict aggregated and dispersed sites, respectively. They found that amino acid composition is effective for predicting aggregated glycosylation sites, while site-specific algorithms are effective for predicting dispersed glycosylation sites. The highest prediction accuracy for aggregated glycosylation sites was 74%, while the highest prediction accuracy for dispersed glycosylation sites was 79%. Independent component analysis revealed that the position-specific presence of amino acid sequences around glycosylation sites was an independent component. The researchers also found that the glycosylation sites of mucins were more likely to map to disordered regions of extracellular proteins.
