REDD1 (Thr23/25) Antibody

Product Specifications

Background

REDD1, Regulated in Development and DNA damage responses 1, is induced by hypoxia, cell stress, and apoptosis. Reduced REDD1 levels can sensitize cells towards apoptosis, where elevated levels of REDD1 induced by hypoxia can desensitize cells to apoptotic stimuli (Schwarzer et al, 2005) . REDD1 has a crucial role in inhibiting mammalian rapamycin complex 1 (mTORC1) signaling during hypoxic stress (Katiyar et al, 2009) . It has been shown that the rapid degradation of REDD1 is mediated by the CUL4A–DDB1–ROC1–b-TRCP E3 ligase complex and is regulated by REDD1 phosphorylation at Thr-25, Thr-23 and Ser-19 through the activity of GSK3b (Katiyar et al, 2009) .

Source

Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr23/25 of human REDD1, conjugated to keyhole limpet hemocyanin (KLH) .

Applications

Purification

Antigen Affinity purification from Pooled whole antiserum

Concentration

Lot Dependent

Dilution

WB (1:300-5000)

Buffer

10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Modification

Phosphorylation

Storage Conditions

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Specificity

Specific for endogenous levels of the ~34 kDa REDD1 phosphorylated at Thr23/25. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.
