Background:

Advancements in glycopeptide identification and glycoproteomic data necessitate sophisticated downstream analysis tools.
Functional and mechanistic studies require robust platforms for mining complex glycoproteomic datasets.

Purpose of the Study:

Introduce StrucGAP (Structural Glycoproteomics Analysis Platform) for scalable, site-specific N-glycoproteomics data mining.
Provide integrated modules for data quality control, glycan characterization, feature extraction, functional annotation, and network analysis.
Enable visualization and insight-tracking for generating chart-based reports and extracting key glycosylation insights.

Main Methods:

Developed StrucGAP, a comprehensive platform integrating multiple analytical modules.
Applied StrucGAP to an uncharacterized aging mouse uterus dataset.
Utilized visualization and insight-tracking functionalities for data interpretation.

Main Results:

Identified bidirectional regulation of core-fucosylation in the aging mouse uterus.
Observed progressive enrichment of sialylation (Neu5Ac), Lewis epitopes, and hybrid glycans.
Linked observed glycosylation changes to functional roles in adhesion and remodeling.

Conclusions:

StrucGAP effectively distills critical glycosylation insights from multi-dimensional structural N-glycoproteome data.
The platform uniquely enables chart-based analysis reports and extraction of key glycosylation insights.
Demonstrated the platform's capability in revealing biologically relevant glycosylation dynamics.
