Figure 1. Schematic representation of the aa sequence of the HIV-1 p17 matrix protein and its derived synthetic fragments. The primary sequence of the full-length p17 protein (132 aa) is shown at the top. Two main regions, designated as the F2 (blue) and the F3 (purple) fragments, were further dissected into shorter sub-fragments to map specific functional sequences. The F2 region (aa 17-36) was subdivided into two smaller peptides: F2 17-22 (EKIRLR) and F2 26-33 (KKKYKLKH). The F3 region (aa 32-52) was truncated into shorter sequences, including F3 37-52 (ASRELERFAVNPGLLE), F3 37-44 (ASRELERF), F3 40-44 (ELERF), and F3 39-43 (RELER). The aa positions are numbered according to the p17 reference sequence. The original illustration was created with Microsoft PowerPoint. aa: Amino acid; HIV-1: Human Immunodeficiency Virus type 1.
