- Abstract:

To address the current challenges in relying solely on single-modal features of target proteins and neglec-tingnetwork-scale features of biological networks, a drug-target affinity prediction (DTA) model based on multimo-dalcross-scale feature fusion was proposed. Target proteins both as sequences and graphs for feature extraction were presented, with semantic and topological features respectively, to enhance the target proteins′ feature representa-tion.The strong affinity relationships between drugs and target proteins were analyzed to construct a heterogeneous graph network of drug-target interaction. A cross-scale feature fusion method was then used to effectively integrate the scale features of the heterogeneous graph network, then to enrich the feature representations of both target pro-teinsand drug molecules. Experimental results on the DAVIS and KIBA datasets demonstrated that, compared with the more advanced model SISDTA, the proposed model achieved reductions in MSE by 0. 015 and 0. 003, respectively,and increases in CI by 0. 005 and 0. 004, respectively, improving the accuracy and stability of affinity pre-diction.It demonstrated the effectiveness of multimodal and cross-scale feature fusion in DTA prediction tasks.
