DEP domain-containing mTOR-interacting protein (DEPTOR) also known as DEP domain-containing protein 6 (DEPDC6) is a protein that in humans is encoded by the DEPTOR gene.[1]
Structure
The gene DEPTOR can be found only in vertebrates. In human, DEPTOR gene locates at chromosome 8, 8q24.12 with protein size 409 a.a.[2] Human DEPTOR contains two N-terminal DEP domains and a C-terminal PDZ domain.[3]
Function
DEPTOR is involved in mTOR signaling pathway as an inhibitor. A direct interaction between DEPTOR and mTOR has been shown.[3] Overexpression of DEPTOR downregulates the activity of mTORC1 while activates mTORC2. mTORC1 and mTORC2 can both inhibit DEPTOR through phosphorylation.[3]
Clinical cancer
Although in most cancer, mTOR pathway is constitutively activated and the expression of DEPTOR is low, one study has found that DEPTOR is overexpressed in multiple myeloma cells and is necessary for their survival.[3]
