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 variants 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.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iF4C22C6CCD5878D2
