This antibody reacts with mouse Connexin 36. On western blots, it identifies a single band at ~36 kDa. The specificity of this antibody was demonstrated using Connexin 36 knockout mice. Reactivity has been confirmed with mouse Connexin 36 transfected HeLa cell lysates, mouse brain, retina and pancreas homogenates.
Intercellular communication through gap junctions plays an important role in a variety of cellular processes including homeostasis, morphogenesis, cell differentiation, and growth control. Interestingly, reduction or alteration in the levels or types of connexin expressed in a given cell type has been found to correlate with tumor progression and metastasis. The murine GJA9, also called connexin-36 (CX36), gene encodes a protein of 321 amino acids most homologous to connexin-35. It is a member of the connexin gene family that is expressed predominantly in mammalian neurons. Connexins associate in groups of 6 and are organized radially around a central pore to form connexons. Each gap junction intercellular channel is formed by the conjunction of 2 connexons. Based on the presence of an intron within its coding region the CX36 gene is suggested to form a new delta subclass of murine connexin genes. Specific cell types in the brain express specific types of connexins; expression and expression patterns coincide with tissue compartmentalization and function. These compartments change during development. Cx36 is the first gap junction protein expressed predominantly in neuronal cells of the mammalian central nervous system. It is highly expressed in adult retina and is present in neurons of the inferior olive, the olfactory bulb, the CA3/CA4 hippocampal subfields and several brain-stem nuclei. Cx36 mRNA expression in the brain gradually increases during fetal development until day seven post-partum when it's expression begins to decline. Biophysical measurements of gap junction channels formed by transfected and endogenous Cx36 indicate that they possess unique properties well suited for mediating flexible electrical and biochemical interactions between neurons.
