General description

Programmed cell death 4 (PDCD4) also known as nuclear antigen H731-like, Protein 197/15a, neoplastic transformation inhibitor protein), is a tumor suppressor protein that is lost in progressed carcinomas of lung, breast, colon and prostate.

Application

Anti-phospho-PDCD4 (pSer67) antibody produced in rabbit has been used in immunoblotting.

Biochem/physiol Actions

Programmed cell death 4 (PDCD4) suppresses translation initiation by specifically inhibiting the helicase activity of eukaryotic translation initiation factor 4A (eIF4A), a component of the translation initiation complex and by competing with eIF4G, a second component of the translation initiation complex, for binding to eIF4A. In response to mitogens, PDCD4 was rapidly phosphorylated on Ser67 by the protein kinase S6K1 and subsequently degraded via the ubiquitin ligase SCF-β (TRCP). It has been shown that the protein is specifically phosphorylated on Ser67 and Ser457 by Akt, both in vitro and in vivo. This phosphorylation causes nuclear translocation of PDCD4.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Triple-negative breast cancer (TNBC) remains clinically challenging as effective targeted therapies are lacking. In addition, patient mortality mainly results from the metastasized lesions. CXCR4 has been identified to be one of the major chemokine receptors involved in breast cancer metastasis.

Ubiquitin-activating enzyme (UAE or E1) activates ubiquitin via an adenylate intermediate and catalyzes its transfer to a ubiquitin-conjugating enzyme (E2). MLN4924 is an adenosine sulfamate analogue that was identified as a selective, mechanism-based inhibitor of NEDD8-activating enzyme (NAE), another E1
