ITSN1 is an endocytic scaffold protein implicated in synaptic functioning. Ca²⁺ is known to be important for endo- cytosis in both pre- and post-synaptic terminals. ITSN1 contains two EH (Eps15 homology) domains which possess putative Ca²⁺-binding EF-hand motifs. Aim. To test the effect of Ca²⁺ on the EH domain binding properties. Methods. His-tag pulldown, Western blotting. Results. Addition of 1.5 mM Ca²⁺ does not affect the binding of the ITSN1 EH domains to the C-terminal fragment of the endocytic protein Epsin 1. Conclusions. The data obtained indicate that Ca²⁺ has no effect on the binding properties of the ITSN1 EH domains.
