DDIT4, ID (REDD1, RTP801, DNA Damage-inducible Transcript 4 Protein, HIF-1 Responsive Protein RTP801, Protein Regulated in Development and DNA Damage Response 1, FLJ20500)

RTP801 was initially identified as a gene induced by DNA damage, and later found to also be regulated by other cellular stresses such as hypoxia and glucocorticoid treatment. Recently, RTP801 has been shown to act as a mediator of tuberous sclerosis complex (TSC)-dependent regulation of the mammalian Target of Rapamycin (mTOR), an evolutionarily conserved serine/threonine kinase that regulates cell growth and cell cycle. In response to energy stress, RTP801 inhibits mTOR function, resulting in dephosphorylation of downstream targets such as ribosomal protein S6 kinase 1 and 4EBP1 and decreasing cell growth. Disregulation of RTP801 may thus contribute to human tumorigenesis.\n\nApplications:\nSuitable for use in ELISA, Western Blot and Immunohistochemistry.
