High impact information on ARAC11/AtROP1/ROP1/ROP1AT

  • These results provide strong evidence that RopGEF1 activates ROP1 in control of polar growth in pollen tubes [1].
  • The RopGEF1 overexpression phenotype was suppressed by expression of a dominant-negative mutant of ROP1, probably by trapping RopGEF1 [1].
  • Tip growth requires the coordinate action of two ROP1 downstream pathways that promote the accumulation of tip-localized Ca2+ and actin microfilaments (F-actin), respectively [2].
  • UDP-glucose transferase, Rop1 and, possibly, annexin [3].
 

Other interactions of ARAC11/AtROP1/ROP1/ROP1AT

  • In vitro GEF assays show that DUF315 but not the full-length version of RopGEF1 has high GEF activity toward ROP1 [1].
