Intersectin 1 forms complexes with SGIP1 and Reps1 in clathrin-coated pits

► Endocytic adaptor ITSN1 interacts with proteins SGIP1 and Reps1. ► Interaction data evidence for triple complex formation comprising ITSN1, SGIP1, Reps1. ► Complexes of ITSN1 with SGIP1 and Reps1 are found in clathrin-coated pits. ► SH3 domain of amphiphysin 1 binds SGIP1 and Reps1.
