ICK

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Required for ciliogenesis (PubMed:24797473). Phosphorylates KIF3A (By similarity). Involved in the control of ciliary length (PubMed:24853502). Regulates the ciliary localization of SHH pathway components as well as the localization of IFT components at ciliary tips (By similarity). May play a key role in the development of multiple organ systems and particularly in cardiac development (By similarity). Regulates intraflagellar transport (IFT) speed and negatively regulates cilium length in a cAMP and mTORC1 signaling-dependent manner and this regulation requires its kinase activity (By similarity).By similarity2 Publications

Juvenile myoclonic epilepsy 10 (EJM10)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of juvenile myoclonic epilepsy, a subtype of idiopathic generalized epilepsy generally characterized by afebrile seizures with onset in adolescence (rather than in childhood) and myoclonic jerks, which usually occur after awakening and are triggered by sleep deprivation and fatigue. EJM10 is an autosomal dominant seizure disorder with variable manifestations, even within families. Affected individuals have febrile, myoclonic, tonic-clonic, or absence seizures, although several seizure types can occur in the same individual. Some patients have onset of seizures in the first years of life.
