The mammalian sorting nexin (SNX) proteins are involved in the endocytosis and the sorting machinery of transmembrane proteins. Additionally to the family defining phox homology (PX) domain, SNX17 is the only member with a truncated FERM (4.1, ezrin, radixin, and moesin) domain and a unique C-terminal region (together designated as FC unit). By gel filtration and lipid overlay assays we show that SNX17 is a non-self-assembling and a PtdIns(3)P high class affinity protein. A SNX17 affinity to any other phosphoinositides was not detected. By yeast two-hybrid- and GST-trapping assays we identified KRIT1 (krev1 interaction trapped 1) as a new specific interaction partner of the FC unit of SNX17. KRIT1 binds SNX17 by its N-terminal region like the known interaction partner ICAP1alpha (integrin cytoplasmic domain-associated protein-1). The interaction was also detected in HEK 293 cells transiently expressing GFP-tagged KRIT1 and Xpress-tagged SNX17. KRIT1 mutations cause cerebral cavernous malformation (CCM1). Our finding suggests a SNX17 involvement in the indicated KRIT1 function in cell adhesion processes by integrin signaling.
