Disease

KIF11_HUMAN Defects in KIF11 are the cause of microcephaly with or without chorioretinopathy, lymphedema, or mental retardation (MCLMR) [MIM:152950. An autosomal dominant disorder that involves an overlapping but variable spectrum of central nervous system and ocular developmental anomalies. Microcephaly ranges from mild to severe and is often associated with mild to moderate developmental delay and a characteristic facial phenotype with upslanting palpebral fissures, broad nose with rounded tip, long philtrum with thin upper lip, prominent chin, and prominent ears. Chorioretinopathy is the most common eye abnormality, but retinal folds, microphthalmia, and myopic and hypermetropic astigmatism have also been reported, and some individuals have no overt ocular phenotype. Congenital lymphedema, when present, is typically confined to the dorsa of the feet, and lymphoscintigraphy reveals the absence of radioactive isotope uptake from the webspaces between the toes.[1]

Function

KIF11_HUMAN Motor protein required for establishing a bipolar spindle. Blocking of KIF11 prevents centrosome migration and arrest cells in mitosis with monoastral microtubule arrays.[2]

Publication Abstract from PubMed

We have identified and synthesized a series of thiophene containing inhibitors of kinesin spindle protein. SAR studies led to the synthesis of 33, which was co-crystallized with KSP and determined to bind to an allosteric pocket previously described for other known KSP inhibitors.

Synthesis and SAR of thiophene containing kinesin spindle protein (KSP) inhibitors.,Pinkerton AB, Lee TT, Hoffman TZ, Wang Y, Kahraman M, Cook TG, Severance D, Gahman TC, Noble SA, Shiau AK, Davis RL Bioorg Med Chem Lett. 2007 Jul 1;17(13):3562-9. Epub 2007 Apr 29. PMID:17498954[3]
