MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene contains a kinase domain most closely related to the cyclin-dependent protein kinases. The encoded kinase may activate cyclin-dependent kinase 2 and is involved in cell growth. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Dec 2009]
PHENOTYPE: Mice homozygous for a null allele display exencephaly, open neural tubes, cleft palate, absence of the floor plate, achondroplasia of the radius and ulna, and abnormal cilia. [provided by MGI curators]
