Study Notes
HIV Proteins and Structure
- Spikes Composition: HIV spikes are comprised of gp120 and gp41 proteins, crucial for virus attachment and entry into host cells.
- Core Formation: The matrix and core of HIV are formed by proteins P17 and P24, essential for structural integrity and protection of viral RNA.
- Virus Classification: HIV is classified as a retrovirus, specifically within the subclass lentivirus, indicating its capacity to integrate into the host genome.
Gene Functionality
- Key Genes: The three main HIV genes—gag, pol, and env—are responsible for synthesizing new HIV particles, enabling replication and expression of the virus.
- Regulatory Genes: Additional genes tat, rev, nef, vif, vpr, and vpu play a vital role in controlling infection and regulating viral life cycle processes, including gene expression and immune evasion.
