text: Mollapour’s laboratory has discovered the tumor suppressor TSC1 and FNIPs function as the new co-chaperones of Hsp90. These two proteins are involved in Tuberous Sclerosis Complex and Birt–Hogg–Dubé syndrome (BHD) syndromes respectively. His research has identified a cross-talk between these two co-chaperones and demonstrated interconnectivity and compensatory mechanisms between the BHD and TSC pathways.
