The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 2 - 3 µg/ml.
Use a concentration of 0.01 - 0.03 µg/ml. Detects a band of approximately 21 kDa (predicted molecular weight: 21 kDa).
FunctionRas proteins bind GDP/GTP and possess intrinsic GTPase activity.
Involvement in diseaseDefects in NRAS 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. Defects in NRAS are the cause of Noonan syndrome type 6 (NS6) [MIM:613224]. A syndrome characterized by facial dysmorphic features such as hypertelorism, a downward eyeslant and low-set posteriorly rotated ears. Other features can include short stature, a short neck with webbing or redundancy of skin, cardiac anomalies, deafness, motor delay and variable intellectual deficits.
Sequence similaritiesBelongs to the small GTPase superfamily. Ras family.
Post-translational modificationsPalmitoylated by the ZDHHC9-GOLGA7 complex. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi.
Cellular localizationCell membrane. Golgi apparatus membrane. Shuttles between the plasma membrane and the Golgi apparatus.
