P35srj is a ubiquitously expressed nuclear protein that binds the transcriptional coactivators p300 and CREB-binding protein (CBP). It is an alternatively spliced isoform of Mrg1, a cytokine-inducible factor that has transformation activity. P35srj interferes with the recruitment of p300/CBP by the transcription factor HIF-1alpha, a process that is essential for the transcriptional response to hypoxia. Here we report the cloning of the human gene CITED2, which encodes p35srj and Mrg1. The CITED2 gene is composed of three exons and two introns. An unusually large (3 kb) CpG island covers both the promoter and the transcribed portions of the gene. The 5'-flanking region of the gene is active as a promoter in transient transfection assays and contains multiple STAT-binding sites, in keeping with its responsiveness to different cytokines. Fluorescence in situ hybridization, and identity to a known human sequence-tagged site (D6S2114), was used to map the CITED2 gene to chromosome 6q23.3.
