Summary
The invention describes the identification and characterization of a FNIP1 homolog, folliculin-interacting protein 2 (FNIP2), that interacts with folliculin, the protein encoded by the FLCN gene, which is responsible for the Birt-Hogg-Dube’ (BHD) syndrome. BHD is a dermatologic disorder associated with an increased risk for developing renal cancer, spontaneous pneumothorax and lung cysts. FNIP2 binds to the C-terminus of folliculin and to AMPK. Importantly, FNIP2 expression was elevated in renal tumors seen in BDH patients. This finding suggests that FNIP2 may serve as a biomarker for BHD.
