CITED2 is a cAMP-responsive element-binding protein (CBP)/p300 interacting transcriptional modulator. CITED-2 has been proposed as a negative regulator for HIF-1 alpha, as it is thought to interfere with the binding of transcription factors HIF-1a and STAT2 to p300/CBP. Recruitment of CBP/p300 by HIF-1 is essential for the transcriptional response to hypoxia.
CITED 2 antibodies are useful tools for research on hypoxic response mechanisms.
