Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
Mutants are hypersensitive to paraquat.
Hk β subunit modulates a wide range of the Sh K+ current properties, inducing its amplitude, activation and inactivation, temperature dependence and drug sensitivity. Modulation is thought to occur via hydrophobic interactions, Hk β subunits modulate Sh channel formation in the cytoplasmic pore region.
