GTPase-activating protein for RHOA and CDC42. Facilitates mitochondrial quality control by promoting Parkin-mediated recruitment of autophagosomes to damaged mitochondria.Negatively regulates the growth of human parainfluenza virus type 2 by inhibiting hPIV-2-mediated RHOA activation via interaction with two of its viral proteins P and V.
基因名
ARHGAP26
蛋白名
Rho GTPase-activating protein 26
亚基
Interacts with NYAP1, NYAP2 and MYO16 (By similarity). Binds to the C-terminus of PTK2/FAK1.
亚细胞定位
Cell junction; focal adhesion. Cytoplasm; cytoskeleton. Colocalizes with actin stress fibers and cortical actin structures.
疾病
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.
