Overview
| Product Description | Mouse Monoclonal antibody [H-RAS-03] recognizes H-Ras |
|---|---|
| Tested Reactivity | Hu |
| Tested Application | WB |
| Specificity | The clone H-RAS-03 reacts with human H-Ras, an ubiquitously expressed 21 kDa intracellular protein. Although reactivity with other species has not been determined, it is probable as the epitope is highly conserved among animals. |

| Background | H-Ras is one of three ubiquitously isoforms of Ras GTPase that operate at the intracellular leaflet of the plasma membrane to regulate multiple signal transduction pathways, such as mitogen-activated protein kinase (MAPK) cascade. H Ras is anchored to the plasma membrane by farnesyl and two palmityl residues. GTP loading decreases H-Ras affinity for lipid rafts and allows the protein to target to nonraft microdomains, the primary sites of H-Ras signaling. Sos protein and other guanine nucleotide-exchange factors catalyze dissociation of GDP from Ras. Besides its roles in the plasma membrane, active H-Ras also diffuses through the cytoplasm on nanoparticles termed rasosomes, which is dependent on Ras palmitoylation. |
| Function | Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. [UniProt] |
| Research Area | Cancer antibody; Cell Biology and Cellular Response antibody; Cell Death antibody; Gene Regulation antibody; Signaling Transduction antibody |
| Calculated MW | 21 kDa |
| PTM | Palmitoylated by the ZDHHC9-GOLGA7 complex. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi. S-nitrosylated; critical for redox regulation. Important for stimulating guanine nucleotide exchange. No structural perturbation on nitrosylation. The covalent modification of cysteine by 15-deoxy-Delta12,14-prostaglandin-J2 is autocatalytic and reversible. It may occur as an alternative to other cysteine modifications, such as S-nitrosylation and S-palmitoylation. Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs). |
