Protein Structure

UniProt Annotation

Function

GTPase-activating protein for RHOA and CDC42.

Subcellular Localization

Cell junction, focal adhesion {ECO:0000250}. Cytoplasm, cytoskeleton {ECO:0000250}. Note=Colocalizes with actin stress fibers and cortical actin structures. {ECO:0000250}.

Disease Associations

Leukemia, juvenile myelomonocytic (JMML) [MIM:607785]: An aggressive pediatric myelodysplastic syndrome/myeloproliferative disorder characterized by malignant transformation in the hematopoietic stem cell compartment with proliferation of differentiated progeny. Patients have splenomegaly, enlarged lymph nodes, rashes, and hemorrhages. Note=The gene represented in this entry is involved in disease pathogenesis. A chromosomal translocation t(5;11)(q31;q23) with KMT2A/MLL1 has been found in leukemic cells from JMML patients, also carrying inactivating mutations on the second allele (PubMed:10908648). {ECO:0000269PubMed:10908648}.
