Summary: Predicted to enable several functions, including ATP hydrolysis activity; ATP-dependent chromatin remodeler activity; and histone binding activity. Involved in several processes, including determination of adult lifespan; neuron development; and segmentation. Located in nucleus. Is expressed in several structures, including epithelium; ganglia; germ layer; gut section; and imaginal disc. Used to study CHARGE syndrome; autism spectrum disorder; and congenital heart disease. Human ortholog(s) of this gene implicated in CHARGE syndrome and hypogonadotropic hypogonadism 5 with or without anosmia. Orthologous to several human genes including CHD6 (chromodomain helicase DNA binding protein 6) and CHD9 (chromodomain helicase DNA binding protein 9).

The CHD Protein, Kismet, is Important for the Recycling of Synaptic Vesicles during Endocytosis.
Title: The CHD Protein, Kismet, is Important for the Recycling of Synaptic Vesicles during Endocytosis.
Kis is important for motor neuron synaptic morphology, the localization and clustering of postsynaptic glutamate receptors, larval motor behavior, and synaptic transmission.
Title: Kismet positively regulates glutamate receptor localization and synaptic transmission at the Drosophila neuromuscular junction.
KIS promotes transcription elongation and counteracts Polycomb group repression via distinct mechanisms. KIS antagonizes Polycomb group repression by facilitating ASH1-dependent H3K36 dimethylation.
Title: The trithorax group proteins Kismet and ASH1 promote H3K36 dimethylation to counteract Polycomb group repression in Drosophila.
the evolutionary conservation of Kismet/CHD8 function in negatively controlling hedgehog expression.
Title: A conserved function of the chromatin ATPase Kismet in the regulation of hedgehog expression.
analysis of this disease model can complement and expand upon the existing studies for this disease, allowing a better understanding of the role of kismet in neural developmental, and Chd7 in CS pathogenesis
Title: Kismet/CHD7 regulates axon morphology, memory and locomotion in a Drosophila model of CHARGE syndrome.
KIS is a key transcriptional regulator of genes that function in the CRY signaling cascade, and thus it plays an important role in the synchronization of circadian rhythms with the dayrationight cycle.
Title: A constant light-genetic screen identifies KISMET as a regulator of circadian photoresponses.
promotes early elongation and counteracts Polycomb group repression by recruiting the ASH1 and TRX histone methyltransferases to chromatin
Title: Drosophila Kismet regulates histone H3 lysine 27 methylation and early elongation by RNA polymerase II.
facilitates an early step in transcriptional elongation by Pol II
