This gene encodes a protein that belongs to the centromere protein family. During cell division, this protein plays a structural role in the maintenance of centrosome integrity and normal spindle morphology, and it is involved in microtubule disassembly at the centrosome. This protein can function as a transcriptional coactivator in the Stat5 signaling pathway, and also as a coactivator of NF-kappaB-mediated transcription, likely via its interaction with the coactivator p300/CREB-binding protein. Mutations in this gene are associated with primary autosomal recessive microcephaly, a disorder characterized by severely reduced brain size and mental retardation. Alternatively spliced transcript variants have been found for this gene.,CENPJ,BM032,CENP-J,CPAP,LAP,LIP1,MCPH6,SASS4,SCKL4,Sas-4,Epigenetics & Nuclear Signaling,Cell Biology & Developmental Biology,Cell Cycle,Centrosome,Centromere,CENPJ
