A putative model of the C9orf72-RAB complex.
a. The structure model of C9orf72 (PDB: 6LT0), Longin domain: orange, DENN domain: blue.
b. DENND1B-RAB35 (PDB: 3TW8), Longin domain: green, DENN domain: red, RAB35: grey.
c. Superimposition of the structure models of C9orf72 and DENND1B-RAB35. The colours are same as (A) and (B). The two structures will adopt a similar overall structure after that the DENN domain of C9orf72 rotates ~90° and moves ~45 Å towards the DENN of DENND1B.
d. The structure model of C9orf72 adopts similar folds to DENND1B.
e. The putative structure model of C9orf72-RAB is generated on the basis of the structure of DENND1B-RAB35.
