"EHBP-1 is required for the endosomal localization of SID-3."; "The EHBP-1 lipid-binding C2-like domain (aa 1-223) interacted strongly with SID-3, while the actin-binding CH domain (aa 260-510) and C-terminal coiled-coil domain (
aa511-901) displayed no affinity for SID-3. Further analysis revealed that the C2-like domain of EHBP-1 interacts with the tyrosine kinase domain (aa 1-370) and the central segment (aa 545-782) of SID-3."
