    Protocol

    Specificity / Sensitivity

    Phospho-RRM2 (Thr33) Antibody recognizes endogenous levels of RRM2 protein only when phosphorylated at Thr33. By western blot, this antibody detects a 110 kDa band of unknown origin.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr33 of mouse RRM2 protein. Antibodies are purified by peptide affinity chromatography.

    Background

    Ribonucleotide reductase catalyzes the rate-limiting step in the synthesis of deoxynucleotide triphosphates (dNTPs). Ribonucleoside-diphosphate reductase subunit M2 (RRM2) is frequently overexpressed and associated with poor prognosis in multiple human cancers (1). RRM2/AKT/NF-κB signaling pathway is implicated in tumor invasiveness in gastric cancer (2). RRM2 is highly expressed in melanoma, and correlated with poor prognosis in BRAF-mutant melanoma. Knockdown of RRM2 stabilized the transient response of cells and patient-derived xenograft (PDX) model system to BRAF inhibition (3).
    Cyclin-dependent kinase (CDK) mediated phosphorylation of RRM2 at Thr33 targets the protein for degradation, allowing cells to maintain balanced dNTP pools (4).
