Rap1 and Rap2 are similar Ras-like G proteins but perform distinct functions. By the affinity chromatography/mass-spectrometry approach and the yeast two-hybrid screening, we identified Misshapen/NIKs-related kinase (MINK) as a novel Rap2-interacting protein that does not interact with Rap1 or Ras. MINK is a member of the STE20 group of mitogen-activated(More)
Rap2A, Rap2B, and Rap2C are Ras-like small G proteins. The role of their post-translational processing has not been investigated due to the lack of information on their downstream signaling. We have recently identified the Traf2- and Nck-interacting kinase (TNIK), a member of the STE20 group of mitogen-activated protein kinase kinase kinase kinases, as a(More)
Rap2 belongs to the Ras family of small GTP-binding proteins, but its specific signaling role is unclear. By yeast two-hybrid screening, we have found that the Caenorhabditis elegans ortholog of Rap2 interacts with a protein containing a Rho-GTPase-activating protein (RhoGAP) domain, ZK669.1a, whose human ortholog PARG1 exhibits RhoGAP activity in vitro.(More)
