HIVP-SAE is a Flask framework-based web server that can be used to predict the susceptibility or resistance of mutant HIV-1 viruses to 5 FDA approved drugs based on the mutant protease sequences.
Drug resistance is one of the most pressing issues in HIV treatment today. The susceptibility testing of HIV-1 drug resistance is essential to developing new anti-viral drugs and optimizing the use of existing drugs. Current methods for HIV resistance testing include phenotypic drug-susceptibility assays to measure drug inhibition of HIV-1 in vitro and genotypic assays that detect mutations known to confer drug resistance. HIVP-SAE is an AI-based method which models the drug susceptibility defined as the ratio of the IC50 of a mutant and a wild-type control. It is implemented as a web server using the Flask framework for quick screening of effective drugs (i.e., protease inhibitors) based on the input of mutant HIV protease sequences.
There are two ways to provide input data to HIV-SAE as described below, and a more detailed instruction is linked to the "Help" button above in the submission form.
In the Form box on the web page, directly input the HIVP mutant sequences in the fasta format. Examples are provided in the Form.
Upload a file containing all HIVP mutant sequences in the fasta format, with ".fasta" as the file extension. An example file is also provided.
HIVP-SAE currently only accepts 20 natural amino acid types in the fasta format, with each amino acid as a single capital letter. Otherwise, the input will be considered as "illegal". If this happens, an error message will show in the Form. However, the program can handle the sequence input very robustly, for instance, if there are spaces between amino acids, or even blank lines, HIVP-SAE will automatically combine all amino acids together as its input. Please see Help for more details.
HIVP-SAE is free for academic research with a user-friendly interface. Currently, no registration is needed to explore its full functionality. However, commercial users should contact us for agreement and support.
Please cite this server. The manuscript has been submitted for peer-reviewed publication, and the preprint is currently available on bioRxiv.
