Background

Connexin 43 (Cx43) is a member of the large family of gap junction proteins. Connexins assemble as a hexamer and are transported to the plasma membrane to create a hemichannel that can associate with hemichannels on nearby cells to create cell-to-cell channels. Clusters of these channels assemble to make gap junctions. Gap junction communication is important in development and regulation of cell growth. Phosphorylation of Cx43 is important in regulating assembly and function of gap junctions (1,2). Ser368 of Cx43 is phosphorylated by protein kinase C (PKC) after activation by phorbol esters, which decreases cell-to-cell communication (3). Src can interact with and phosphorylate Cx43 to alter gap junction communication (4,5).

Western Blotting Image 1: Connexin 43 (E7N2R) XP® Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using Connexin 43 (E7N2R) XP® Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Low expression of connexin 43 protein in BeWo cells is consistent with the predicted expression pattern.

Western blot analysis of extracts from control 293T cells (lane 1) or connexin 43 knockout 293T cells (lane 2) using Connexin 43 (E7N2R) XP® Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). The absence of signal in the connexin 43 knockout 293T cells confirms specificity of the antibody for connexin 43.
