BBS1 is the most important BBSome subunit for cargo recognition as it mediates the interaction of the GTP-bound Arf-like GTPase ARL6 with the BBSome, a critical step in the recruitment of the BBSome to membranes [2]. This entry represents the GAE domain of BBS1, found at the C-terminal. It adopts a beta-sandwich fold [2]. This domain mediates interactions with other subunits (BBS8 and BBS9) of the complex.
