pMEV2HA-P53-DN

Human p53 Xpress Clones

The p53 protein is a nuclear phosphoprotein of 53 kDa. It is a tumor suppressor protein critical for regulation of the cell cycle in response to genotoxic insults such as radiation or chemicals resulting in DNA damages. The highly conserved vertebrate p53 gene is one of the most frequently mutated genes found in human cancers, being either lost or mutated in over half of all human tumors. It has therefore become the center of intensive study ever since the link of p53 mutations with various human cancers was realized. The expression level of several important genes including p21, MDM2, GADD45 (CHOP), Bax and cyclin G was modulated by p53. Among many other roles, it is involved in arresting the cell cycle at G1 phase upon DNA damages.

The native p53 protein is a tetramer in solution and functions as a transcription factor that binds to specific DNA sequences. Many P53 mutations, especially those lie within the DNA-binding domain (so-called hot-spot mutations), show dominance over wild type protein. Replacement of valine 143, one of the hot-spot residues, results in a mutant (V143A) with a transdominant-negative effect on several activities of wild type p53. V143A is also a temperature-sensitive mutant: it shows DNA binding and transcriptional activity at 32oC, but it is inactive at 37oC.

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.
