Autoimmunity can develop from an often undetermined interplay of genetic and environmental factors. Rare forms of autoimmune conditions may also result from single gene mutations as for autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy, an autosomal recessive disease associated with mutated forms of the

The principal alpha subunit of voltage-gated sodium channels is associated with auxiliary beta subunits that modify channel function and mediate protein-protein interactions. We have identified a new beta subunit termed beta4. Like the beta1-beta3 subunits, beta4 contains a cleaved signal

The redox states of proteins in cells are key factors in many cellular processes. To determine the redox status of cysteinyl thiol groups in proteins in vivo, we developed a new maleimide reagent, a photocleavable maleimide-conjugated single stranded DNA (DNA-PCMal).
