Product Specific Information
This antibody detects endogenous levels of Connexin 43 (GJA1) only when phosphorylated at Ser373.
Target Information
Connexin 43 (Cx43) is a member of the gap junction protein family. Connexins assemble as hexamers and are transported to the plasma membrane to form hemichannels that connect with adjacent cells to create cell-to-cell channels. These clusters form gap junctions, which are essential for intercellular communication, development, and cell growth regulation.
Phosphorylation of Cx43 regulates gap junction assembly and function. Ser368 of Cx43 is phosphorylated by protein kinase C (PKC), reducing cell-to-cell communication. Src kinase can also phosphorylate Cx43, modulating junctional communication. Connexin 43 is the major gap junction protein in the heart, playing a crucial role in synchronized contraction and embryonic development. Mutations in related genes can cause various inherited diseases.
