Beschreibung

Allgemeine Beschreibung

Pathway Explorer Antibody MiniPack:
Each Pathway Explorer Antibody Minipack contains three related antibodies as part of a signaling cascade or a combination of total and phosphorylated forms of key signaling targets. Each of the three antibodies are 30% the original pack size. Full size versions of each of the Pathway Explorer antibodies are available for sale individually under the same catalog number with the removal of “SP” off of each one (e.g. 05-591SP can be ordered as 05-591).

ATM:
Ataxia telangiectasia mutated kinase (ATM) and ataxia telangiectasia and Rad3-related kinase (ATR) are related kinases that regulate cell cycle checkpoints and DNA repair. Mutation in the ATM gene results in the autosomal recessive disease ataxia telangiectasia (AT). The identified substrates for ATM are p53, p95/NBS1, MDM2, Chk2, BRCA1, CtIP, 4E-BP1 and Chk1. The essential requirement for the substrates of ATM/ATR is S/TQ. Hydrophobic amino acids at positions -3 and -1, and negatively charged amino acids at position +1 are positive determinants for substrate recognition by these kinases. Positively charged residues surrounding the S/TQ are negative determinants for substrate phosphorylation. The complex phenotype of cells derived from patients with AT suggests that ATM has additional cellular substrates. In unirradiated cells, ATM is present as an inactive homodimer or multimer. Double-stranded breaks in DNA caused by ionizing radiation cause rapid ATM kinase activation through dissociation of this complex and ATM autophosphorylation at Ser1981.

Chk2:
The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in p53 signaling, including Chk2, p53R2, p53AIP1, Noxa, PIDD, and PID/MTA2, were recently discovered. The checkpoint kinase Chk2 is the mammalian homologue of yeast Cds1/Rad53. In response to DNA damage, the checkpoint kinase ATM phosphorylates and activates Chk2, which in turn directly phosphorylates and activates p53. Chk2 serves as ATM downstream effector to mediate activation of p53. Chk2 also phosphorylates and activates BRCA1, the product of a tumor suppressor gene that is mutated in breast and ovarian cancer.
