H-Ras protein

• Catalog Number: orb533497
• Category: Proteins
• Description: Ras proteins are members of the superfamily of small GTP-binding proteins that function as molecular switches controlling a variety of signaling and transport pathways. H-Ras is one of the classic human Ras proteins (H-, N-, K-Ras4A, and K-Ras4B). Suitable as a substrate for farnesyltransferase. Protein preparation is 98% GDP-and 2% GTP-loaded, measured by HPLC.
