WormMine: Gene WBGene00002235

• WormBase Gene ID: WBGene00002235
• Gene Name: kqt-3
• Sequence Name: Y54G9A.3
• Brief Description: kqt-3 encodes one of three C. elegans KCNQ-like potassium channel subunits and, with respect to humans, is most similar to the KCNQ1 channel protein which when mutated leads to inherited long QT syndrome (OMIM:607542); although loss of KQT-3 activity via large-scale RNAi screens results in no obvious abnormalities, KQT-3 likely functions to regulate cellular excitability as expression of KQT-3 in Xenopus oocytes can produce K+ channel currents that functionally resemble vertebrate M-currents; activity of these KQT-3 channels can be suppressed by coexpression with the human M1 muscarinic receptor and treatment with diacylglycerol analogs, although KQT-3 is less sensitive to each of these treatments than KQT-1; a KQT-3::GFP fusion protein is expressed in the anterior- and posterior-most intestinal cells, the anterior and posterior mechanosensory neurons ALM and PLM, amphid and phasmid neurons, and in some additional head neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Enables potassium channel activity. Involved in G protein-coupled acetylcholine receptor signaling pathway and potassium ion transport. Predicted to be located in membrane. Predicted to be part of voltage-gated potassium channel complex. Expressed in head neurons; intestine; and sensory neurons. Used to study Jervell-Lange Nielsen syndrome. Human ortholog(s) of this gene implicated in several diseases, including heart conduction disease (multiple); long QT syndrome (multiple); and type 2 diabetes mellitus. Is an ortholog of human KCNQ1 (potassium voltage-gated channel subfamily Q member 1).

6 Expression Patterns

• Primary Identifier: Expr1031312
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr3236
• Pattern: Translational fusions of kqt-3 gene with GFP revealed prominent expression in a variety of C. elegans tissues including intestinal cells, mechanosensory neurons, chemosensory neurons, and other head neurons. The mechanosensitive touch neurons PLM and ALM were clearly labeled by kqt-3::GFP. In addition, a large subset of DiI-positive chemosensory amphid and phasmid neurons consistently labeled with kqt-3::GFP. These identified kqt-3::GFP positive neurons included the amphid neurons ADL, ASI, AWB, and ASH located in the head, and the phasmid neurons PHA and PHB in the tail. An additional DiI-negative neuron in the head labeled consistently with kqt-3::GFP, which were tentatively identified as the chemosensory neuron AWC. Additional unidentified head neurons were labeled by kqt-3::GFP, although expression was not reliably observed in neurons of the ventral or dorsal cord.

The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.
