原癌基因N-Ras重组兔单抗

NRAS

GTPase NRas

Interacts (active GTP-bound form preferentially) with RGS14. Interacts (active GTP-bound form) with RASSF7.

Cell membrane; Lipid-anchor; Cytoplasmic side. Golgi apparatus membrane; Lipid-anchor. Note=Shuttles between the plasma membrane and the Golgi apparatus.

Widely expressed.

Palmitoylated by the ZDHHC9-GOLGA7 complex. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi.
Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs).

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 disease is caused by mutations affecting the gene represented in this entry.
Noonan syndrome 6 (NS6) [MIM:613224]: A form of Noonan syndrome, a disease characterized by short stature, facial dysmorphic features such as hypertelorism, a downward eyeslant and low-set posteriorly rotated ears, and a high incidence of congenital heart defects and hypertrophic cardiomyopathy. Other features can include a short neck with webbing or redundancy of skin, deafness, motor delay, variable intellectual deficits, multiple skeletal defects, cryptorchidism, and bleeding diathesis. Individuals with Noonan syndrome are at risk of juvenile myelomonocytic leukemia, a myeloproliferative disorder characterized by excessive production of myelomonocytic cells. Note=The disease is caused by mutations affecting the gene represented in this entry.
Autoimmune lymphoproliferative syndrome 4 (ALPS4) [MIM:614470]: A disorder of apoptosis, characterized by chronic accumulation of non-malignant lymphocytes, defective lymphocyte apoptosis, and an increased risk for the development of hematologic malignancies. Note=The disease is caused by mutations affecting the gene represented in this entry.

Belongs to the small GTPase superfamily. Ras family.

Ras proteins bind GDP/GTP and possess intrinsic GTPase activity.
