Monoclonal Mouse Affinity Purified E B IF
Intracellular communication mediated by gap junctions plays an important role in a variety of cellular processes including homeostasis, morphogenesis, cell differentiation, and growth control. Gap junctions are transmembrane channels that serve to directly link neighboring cells by mediating the exchange of low-molecular weight metabolites, ions, and second messengers. Gap junctions are formed by the interaction of connexons or hemichannels on adjacent cells. The connexon itself is composed of a hexameric assembly of proteins referred to as connexins. Connexins are highly homologous proteins encoded by a multigene family. The connexins exhibit similar structural features which include a cytoplasmic amino terminal region, four transmembrane domains, two extracellular loops, and a carboxy-terminal cytoplasmic tail of varying length. Comparison of the amino acid sequences of the various connexin family members indicate that the two areas of greatest divergence amongst the connexin family members are the intracellular loop connecting the second and third transmembrane. Speci c for one of the unphosphorylated forms of Connexin 43.Connexin 43 can be phosphorylated at multiple sites. Recent studies have shown that phosphorylation occurs at a serine within the epitope recognized by this antibody.

Clone TypeMonoclonal
IsotypeIgG1,k
Clone No3G106
HostMouse
SourceRat
Concentration~0.5mg/ml
FormSupplied as a liquid in PBS, pH 7.4, 0.1% sodium azide.
PurityPurified by immunoaf nity chromatography.
ImmunogenSynthetic peptide corresponding to a cytoplasmic sequence located near the C-terminus of rat Connexin 43.
SpecificityRecognizes rat Connexin 43 only when the serine at residue 368 is unphosphorylated. Does recognize Connexin 43 if it is phosphorylated at sites other than Ser368. In some cell types, crossreactivity with a ~70kD protein of unknown identity has been observed. This crossreactivity is likely due to a shared epitope. Species Crossreactivity: canine, human and mouse
