Connexin 43 Rabbit anti-Human, Mouse, Rat, Polyclonal, Invitrogen™
Rabbit Polyclonal Antibody
Manufacturer: Invitrogen PA137497
This antibody is predicted to react with bovine, canine, mouse, porcine and rabbit based on sequence homology. Heat-mediated antigen retrieval is recommended prior to staining, using a 10mM citrate buffer, pH 6.0, for 10 minutes followed by cooling at room temperature for 20 min. Following antigen retrieval, incubate samples with primary antibody for 10 min at room temperature. A suggested positive control is heart tissue.Connexin 43 (Cx43) is a member of the gap junction protein family. 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. Ser368 of Cx43 is phosphorylated by protein kinase C (PKC) after activation by phorbol esters, which decreases cell-to-cell communication. Src can interact with and phosphorylate Cx43 to alter gap junction communication. GFAP are membrane-spanning proteins that facilitate the transfer of ions and small molecules between cells. According to sequence similarities at the nucleotide and amino acid levels, the gap junction proteins are divided into two categories, alpha and beta. Connexin 43 is the major protein of gap junctions in the heart, and gap junctions are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. Connexin 43 is also targeted by several protein kinases that regulate myocardial cell-cell coupling. A related intron-less connexin 43 pseudogene, GJA1P, has been mapped to chromosome 5. Mutations in the GFAP gene cause X-linked Charcot-Marie-Tooth disease, an inherited peripheral neuropathy, oculodentodigital dysplasia and heart malformations. Alternatively spliced transcript variants of GFAP have been found.
