High impact information on ark-1

  • A screen for synthetic enhancers of sli-1 identified ark-1 (forAck-related tyrosine kinase), a novel inhibitor of let-23 EGFR signaling in C. elegans [1].
  • An ark-1 mutation synergizes with mutations in other negative regulators of let-23, resulting in increased RAS signaling [1].
  • Further, we identify an inhibitory tyrosine of LET-23 requiring sli-1(+) for its effects: removal of this tyrosine closely mimics the loss of sli-1 but not of another negative regulator, ark-1 [2].
