  • Function

    GTPase-activating protein for RHOA and CDC42.
  • Involvement in disease

    Defects in ARHGAP26 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:607785]. JMML is a pediatric myelodysplastic syndrome that constitutes approximately 30% of childhood cases of myelodysplastic syndrome (MDS) and 2% of leukemia. Chromosomal translocation t(5;11)(q31;q23) with MLL has been found in a JMML patient.
  • Sequence similarities

    Contains 1 PH domain.
    Contains 1 Rho-GAP domain.
    Contains 1 SH3 domain.
  • Cellular localization

    Cell junction > focal adhesion. Cytoplasm > cytoskeleton. Colocalizes with actin stress fibers and cortical actin structures.
