    ..Interestingly, CeRac1 and CDC42Ce are found at the same location, which might point to their common involvement in hypodermal cell fusion, a crucial morphogenetic event for nematode development. ..

    ..The CePAK::GFP fusion protein was preferentially localized to the cell surface in pharyngeal muscles. ..

    ..We propose that the interaction between activated CED-10/Rac1 and MIG-10/lamellipodin triggers local cytoskeletal assembly and polarizes outgrowth activity in response to UNC-6/netrin. ..

    ..Our findings should help understand how hemidesmosome dynamics are regulated in vertebrate systems. ..

    ..We suggest that similar pathways could promote epithelial morphogenesis or wound healing in other organisms in which epithelial cells adhere to tension-generating contractile cells...

    ..2 gene activation) of this worm could be used as the first indicator of extended lifespan for a quick in vivo screening for PAK1-blockers...
  8. Kennedy L, Pham S, Grishok A. Nonautonomous regulation of neuronal migration by insulin signaling, DAF-16/FOXO, and PAK-1. Cell Rep. 2013;4:996-1009 pubmed publisher
    ..Because a FOXO-Pak1 pathway was recently shown to regulate mammalian neuronal polarity, our findings indicate that the roles of FOXO and Pak1 in neuronal migration are most likely conserved from C. elegans to higher organisms. ..

    ..Moreover, we suggest that ROCK and PAK regulate at least one other target essential for elongation, in addition to MLC-4. ..
