Human K-Ras 2B Xpress Clones
Ras proteins are members of small GTPase superfamily. They bind GDP/GTP and possess intrinsic GTPase activity. These proteins act as switches to turn on/off their downstream target proteins in response to upstream stimuli because they can alternate between an inactive form bound to GDP and an active form bound to GTP. Activating mutations of KRAS2, including G12V, have been implicated in various malignancies, including lung denocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. On the other hand, S17N is a widely used dominant negative mutant.
Alternative splicing of KRAS-2 gene leads to variants encoding two isoforms that differ in the C-terminal region. KRAS-2B variant terminates in exon 4b, encoding a unique C terminus and lacks exon 4a that is present in the longer transcript variant KRAS-2A.
Gene Name: Homo sapiens v-Ki-ras2 Kirsten rat sarcoma 2 viral oncogene homolog (KRAS2), transcript variant B. Other Names: Transforming protein p21b, K-Ras 2B, Ki-Ras, c-K-ras

Maintenance of plasmid clones
Upon receiving of the plasmids, briefly spin the vials to collect contents to the bottom before storing at 2-8oC if will be used shortly, or -20 oC for long term storage. It is recommended that you propagate the vectors in E. coli strains that are recombinant deficient (recA) and endonuclease A-deficient (endA) (e.g. DH5α or XL1-Blue).

About Xpress Clones
Xpress Clones are a collection of expression verified genes, including protein kinase genes, dominant negative mutants, consititutively active mutants and kinase deficient mutants, and other expression ready genes. Unlike other collections aiming to have more genes, we focus on the genes important to your research, the mutations with a meaning to your experiment.
If your gene of interest is not in our list, please let us know and we can clone the genes with desired mutant forms, expression verified in the organism you choose.
