 It can also form heterodimers with the related proteins CEBP-alpha, CEBP-delta, and CEBP-gamma.The encoded protein is important in the regulation of genes involved in immune and inflammatory responses and has been shown to bind to the IL-1 response element in the IL-6 gene, as well as to regulatory regions of several acute-phase and cytokine genes.In addition, the encoded protein can bind the promoter and upstream element and stimulate the expression of the collagen type I gene.
