CD28 mediates transcriptional upregulation of the interleukin-2 (IL-2) promoter through a composite element containing the CD28RE and NF-IL-2B AP-1 sites.

abstract：:All inbred strains of mice carry the Ren-1 structural gene, which encodes the renin-1 isozyme, the classical renin activity found in kidneys. In addition, some strains carry a second renin structural gene, Ren-2, which encodes the predominantly expressed submaxillary gland renin isozyme, renin-2. Ren-1 and Ren-2 exhib...
