G3BP1 and neoplasm: To further explore the role of CAPRIN1 in the tumor suppression process by circVAMP3, we analyzed the interaction network of CAPRIN1 and other proteins using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database.[20] The network showed that G3BP1 protein had the highest correlation with CAPRIN1 (Figure 3d and Figure S3f, Supporting Information).
