General description
Connexins are highly homologous proteins that assemble as hexamers (connexons) to form gap junctions, small channels which allow for the passage of ions and other small molecules up to 1,200 daltons between neighboring cells. Gap junctions play an important role in a variety of cellular processes including homeostasis, intercellular metabolic cooperation and synchronization, morphogenesis, cell differentiation, and growth control. The most broadly studied connexins are the 26, 32, 43 and 45 kDa isoforms. Connexin 43 is a 382 a.a. protein belonging to the alpha-type (Group II) subfamily of connexin proteins and possessing four transmembrane regions, with cytoplasmic amino and carboxyl terminals. It undergoes rapid turnover in the cell and its monomers may reside in the ER/Golgi network, forming a reservoir available for assembly upon degradation of existing connexin-43 channels. Connexin 43 has been detected in a variety of tissues including: atrial and ventricular myocytes, granulose cells, astrocytes, fibroblasts, leptomeningeal cells, brain, lung, smooth muscle, uterine muscle, kidney, lens, epithelium, cornea and testis. Connexin 43 also may have a role in communication between migrating cardiac neural crest cells.
Specificity
Connexin-43. Recognizes proteins of molecular weight 43-47 kDa on Western blots of mouse brain lysate. Mouse connexin 43 sequence is identical in rat and bovine, and differs by one amino acid in pig. This sequence has no known homology with other connexins. Also effective for detection of Cx43 in mouse keratinocyte cells and on frozen sections of rat heart.
Immunogen
A synthetic peptide corresponding to positions 252-270 of the mouse connexin 43 sequence. This sequence is identical in rat and bovine.
Epitope: C-terminus
Application
Anti-Connexin 43 Antibody, clone 4E6.2 detects level of Connexin 43 & has been published & validated for use in ELISA, IC, IH & WB.
