SREBF2 and renal carcinoma: Another intrinsic protein encoding an E3 ubiquitin ligase in ER, TRC8 (translocation in renal cancer from chromosome 8), is capable of binding both SREP-2 and SCAP to form a TRC8/SREBP-2/SCAP complex, which hampers the interaction between SCAP and Sec24, a COPII protein, to reduce the cleavage of SREBP-2 (34).
