Betacellulin Recombinant, Human (BTC, Probetacellulin)
20ug
Molecular Biology Storage: -20CShipping: Blue Ice
Betacellulin (BTC) is a widely expressed EGF-related polypeptide growth factor, proteolytically processed into a soluble mature form, which acts as a potent inducer of mitosis in vascular smooth muscle cells and retinal pigment epithelial cells. BTC signals through binding to the homodimeric ErbB-1 and ErbB-4 receptors, but also appears to uniquely bind to and activate all known heterodimeric ErbB receptors.
