Antimicrobial peptides (AMPs) play a significant role in guiding drug
design, advancing targeted therapies, and cancer treatment research. The
function of peptides is highly associated with their three-dimensional
structure. AMPs particularly favor alpha-helical structures, or
alpha-folds, due to their ability to disrupt the protective layers that
surround cells effectively and their structural stability. Existing
classifiers mainly identify AMPs but overlook their structural fold
which can provide valuable insights into their function. To address this
limitation, we introduce an innovative multitask classifier that
recognizes AMPs and predicts their alphahelical folds simultaneously.
Our approach employs k-mers and Transformer networks for efficient,
accurate multitask classification. Results on the datasets indicate
comparable performance compared to single-task methods in half the time
and complexity.@INPROCEEDINGS{10446946,
