The Alternatively Spliced Form “b” of the Epithelial Sodium Channel α subunit (α ENaC): Any Prior Evidence of its Existence?
The epithelial sodium channel (ENaC) is critical in maintaining sodium balance across aldosterone-responsive epithelia. ENaC is a combined channel formed of three subunits (αβγ) with α ENaC subunit being the most critical for channel functionality. In a previous report, we have demonstrated the existence and mRNA expression levels of four alternatively spliced forms of the α ENaC subunit denote...
متن کاملExpression of alternatively spliced sodium channel alpha-subunit genes. Unique splicing patterns are observed in dorsal root ganglia.
Molecular medicine requires the precise definition of drug targets, and tools are now in place to provide genome-wide information on the expression and alternative splicing patterns of any known gene. DNA microarrays were used to monitor transcript levels of the nine well-characterized alpha-subunit sodium channel genes across a broad range of tissues from cynomolgus monkey, a non-human primate...
متن کاملThe Epithelial Sodium Channel α subunit (α ENaC) alternatively spliced form "b" in Dahl rats: What's next?
BACKGROUND The amiloride-sensitive Epithelial Sodium Channel (ENaC) is critical in maintaining Na+ balance, extracellular fluid volume and long term blood pressure control. ENaC is composed of three main subunits alpha, beta, & gamma. While alpha ENaC is critical for channel functionality, beta & gamma ENaC maximize channel function. To date, there are four alternatively spliced forms of the al...
متن کاملSodium current density correlates with expression of specific alternatively spliced sodium channel mRNAs in single neurons.
Elements within the first cytoplasmic loop of voltage-gated sodium channels have been implicated in regulating channel function. We have examined the role of alternative splicing within the first cytoplasmic loop of the Drosophila sodium channel gene para in regulating sodium current expression, using single-cell RT-PCR. In addition to a previously described exon (a), we identified a second exo...
