A	small GTPase superfamily, ARF type M-CSA #628	The GTP dependent protein Arl-2 is part of a family of close relatives of the Arf proteins. Although the function of the Arf proteins themselves has been determined (they are involved in regulating vesicular transport) the function of the Arl family has not yet been determined. The protein Arl-2 interacts with PDEdelta which is a relative of the important signalling protein Rho, thus suggesting Arl-2 regulates transport by PDEdelta. As Ras interacts with Rho, it is not surprising that the mechanism of GTP hydrolysis employed by Arl-2 is similar to that found in Ras. Therefore study of this protein may shed insight into an area of highly important cancer research.
