N2 - Arl2 and Arl3, members of the Arf subfamily of small G proteins, are believed to be involved in ciliary and microtubule-dependent processes. Recently, we could identify RP2, responsible for a variant of X-linked retinitis pigmentosa, as the Arl3-specific GAP. Here, we have characterized Arl2/3 interactions. We show the formation of a ternary complex between Arl3, its cognate GAP RP2 and its retinal effector HRG4. This complex seems to be important for photoreceptor function.
