背景介绍 TAK1 is a serine/threonine protein kinase that mediates signaling by TGFβ and morphogenetic protein (BMP) (1). In response to IL-1, TAK1 forms a kinase complex with TAB1 and this complex is required for the activation of nuclear factor kappa B (Nf?B). TAK1 can also activate MAPK8/JNK and MAP2K4/MKK4 and thus play a role in the cell response to environmental stress. Tak1 is essential for thymocyte development and activation and deletion of TAK1 prevents maturation of single-positive thymocytes displaying CD4 or CD8 (2). Thymocytes lacking TAK1 fail to activate Nf?B and JNK and are prone to apoptosis upon stimulation. 产品介绍 Recombinant fusion protein consisting of human proteins TAK1 (TGFβ-activated kinase 1), also known as MAP3K7 (Mitogen-activated protein kinase kinase kinase 7), Genbank Accession #NM_003188, a.a. 1-303, and human TAB1 (TAK1-binding protein), Genbank Accession #NM_006116, a.a. 437-end, linked by a small peptide (DFGGGGG), and with an N-terminal GST-tag, MW = 74 kDa, expressed in Sf9 cells via a baculovirus expression system.
