HIV-1 REV peptide apatmer
Timeline
Jensen KB and Green L produced small RNA ligands with high affinity for HIV-1 Rev protein by SELEX in vitro evolution method for a series of chemical modification studies[1]
The solution structure of the 35-mer high affinity RNA aptamer binding site of HIV-1 17-mer rev peptide was determined by NMR molecular dynamics[2]
The study showed that the RNA structure determines whether the same HIV-1 Rev peptide folds into an extended conformation or an alpha-helical conformation at the time of complex formation[3]
The solution structure of HTLV-1 arginine-rich Rex peptide bound to its RNA aptamer target as determined by multidimensional heteronuclear NMR was demonstrated[4]
It was demonstrated that HIV Rev, which is limited by the limited viral genome, can also form organized RNP by assembling homologous oligomers on Rev reaction element (RRE) RNA[5]
The arginine-rich RNA-binding motif of HIV-1 Rev is intrinsically disordered and folds upon RRE binding[6]
Description
In 1994, Jensen KB and Green L produced small RNA ligands with high affinity for HIV-1 Rev protein by SELEX in vitro evolution method for a series of chemical modification studies. In 1996, Ye X and Gorin A combined NMR molecular dynamics method have been applied to determine the solution structure of the HIV-1 17-mer rev peptide binding to its 35-mer high affinity RNA aptamer binding site[1,2].SELEX

SELEX ligand
Jensen KB and Green L Select rna that is chemically modified under denaturation conditions and assign it through a filter for Rev binding. Selected at Rev concentrations of 30, 6, and 1 "2 nM (binding buffer volumes of 1.5 and 25 ml, respectively), 200 mM potassium acetate, 50mM Tris 'hci (pH 7" 7), 10 mM I)TT. About 3pmo of modified RNA was added to each protein solution, mixed and stored in ice or 15 rain, then transferred to 37o(' 10 rain). The binding solution is flushed with 5ml of binding buffer through the pre-wet nitrocellulose filter. The RNA is eluted from the membrane and the remaining modification sites are detected. The modified RNA is also labeled on a filter and elutes to check for uniform recovery of the modified RNA[1].Name | Sequence | Ligand | Affinity |

Similar compound
We used the Dail server website to compare the structural similarities of ligand proteins, and chose the top 10 in terms of similarity for presentation. The Dali server is a network service for comparing protein structures in 3D. Dali compares them against those in the Protein Data Bank (PDB). Z-score is a standard score that is converted from an original score. The list of neighbours is sorted by Z-score. Similarities with a Z-score lower than 2 are spurious. RMSD(Root Mean Square Deviation) value is used to measure the degree to which atoms deviate from the alignment position.
