HIV N-linked Glycosylation Site Analyzer

HIV N-linked Glycosylation Site Analyzer analyzes N-linked glycosylation sites in HIV-1 gp120 sequences to map and compare glycosylation patterns and to refine gp120 alignments using Envelope variable loops for studies of viral diversity and evolution.

Key Features:

• Automated Mapping: Maps N-linked glycosylation sites across diverse HIV-1 gp120 sequence populations.
• Comparative Analysis: Compares glycosylation site presence and patterns among different HIV-1 strains.
• Sequence Alignment Refinement: Uses N-linked glycosylation sites as alignment anchors to refine gp120 sequence alignments in highly variable regions.

Scientific Applications:

• HIV diversity and evolution studies: Enables analysis of glycosylation pattern variation to investigate HIV-1 population diversity and evolutionary trajectories.
• Immune escape and vaccine design: Provides data on glycosylation changes relevant to mechanisms of immune evasion and considerations for vaccine antigen design.
• Phylogenetic and evolutionary analyses: Improves accuracy of gp120 alignments to support phylogenetic inference and evolutionary studies.

Methodology:

n-glyco leverages the enrichment of N-linked glycosylation sites within the Envelope variable loops of HIV-1 as focal anchors to map glycosylation sites and enhance gp120 sequence alignment.
