There are many diseases related to ion channels. Mutations in muscle voltage-gated sodium, potassium, calcium and chloride channels, and acetylcholine-gated channel may lead to such physiological disorders as hyper- and hypokalemic periodic paralysis, myotonias, long QT syndrome, Brugada syndrome, malignant hyperthermia and myasthenia. Neuronal disorders, e.g., epilepsy, episodic ataxia, familial hemiplegic migraine, Lambert-Eaton myasthenic syndrome, Alzheimer's disease, Parkinson's disease, schizophrenia, hyperekplexia may result from dysfunction of voltage-gated sodium, potassium and calcium channels, or acetylcholine- and glycine-gated channels. Some kidney disorders, e.g., Bartter's syndrome, policystic kidney disease and Dent's disease, secretion disorders, e.g., hyperinsulinemic hypoglycemia of infancy and cystic fibrosis, vision disorders, e.g., congenital stationary night blindness and total colour-blindness may also be linked to mutations in ion channels.

We investigated the regulation of the cjaA and cjaB genes of Campylobacter coli. These genes are seemingly arranged into one operon but appear to encode functionally different proteins i.e. an extracytoplasmic solute receptor and a MHS - metabolite: H+ symporter transport protein. Analysis of various transcriptional cjaA and/or cjaB lacZ fusion constructs revealed that both genes are arranged in an operon. RACE analysis located the transcription start site of the cjaAB operon 46 bp upstream of the translation start point. Beta-galactosidase reporter assays yielded much higher activity for the cjaA than the cjaB gene fusion products. RT-PCR showed unequal amounts of mRNA, indicating differential post-transcriptional processing of cjaA and cjaB mRNA possibly related to the presence of inverted repeats in the intergenic region. Phylogenetic analysis grouped CjaB into a new MHS sub-family together with potential transporters with uncharacterised functions of Campylobacter and Helicobacter. Notably, no CjaB family members were identified in epsilon-Proteobacteria from different ecological niches, such as H. hepaticus and Wolinella succinogenes.
