KRAS G13D Protein, Human, Recombinant, AviTag

$ 500.00

Human KRAS protein is a small guanosine triphosphatase (GTPase) that is the component of the mitogen activated protein kinase (MAPK) signaling pathway. High occurrences of KRAS mutations in some types of cancers make KRAS one of the most important targets in oncology for drug development. The four most frequent KRAS mutations are G12D, G12V, G13D, and G12C.

Recombinant KRAS G13D protein with the N-terminal AviTag™ peptide and His-tag is produced in E. coli cells. Presence of AviTag™ peptide can be useful for a site-specific biotinylation with BirA enzyme (

Sequence of recombinant human KRAS G13D protein (amino acids 1 – 185; G13D mutant variant of isoform KRAS4B (UNIPROT: P01116-2))




Loading of the KRAS proteins with nucleotides or nucleotides' analogs can be performed if requested.
