Transforming Growth Factor (TGF) alpha [1E8-G6]

Transforming Growth Factor, alpha (TGF-a) is a 50 amino acid peptide that is involved in the regulation of normal and malignant cell growth. The mature peptide is released following proteolytic cleavage from a 160 amino acid transmembrane precursor molecule. It is one of the various ligands for EGFR and seem to be involved in the growth regulation of intestinal mucosa and might be related to the development and progression of gastrointestinal tumors. Macrophages secrete TGF-a to trigger proliferation of cancer cells. TGF-a is synthesized by several cells, like epidermal keratinocytes, fibroblasts, and cells of hematopoetic origin like eosinophils and stimulated macrophages.
