ID:CEP63_HUMAN DESCRIPTION: RecName: Full=Centrosomal protein of 63 kDa; Short=Cep63; FUNCTION: Required for normal spindle assembly. Maintains centrosome numbers through centrosomal recruitment of CEP152. Also recruits CDK1 to centrosomes. Plays a role in DNA damage response. Following DNA damage, such as double-strand breaks (DSBs), is removed from centrosomes; this leads to the inactivation of spindle assembly and delay in mitotic progression (By similarity). SUBUNIT: Interacts with CEP152 and CDK1; these interactions recruit both ligands to centrosomes. May also interact with CDK2. INTERACTION: Q9NRI5:DISC1; NbExp=7; IntAct=EBI-741977, EBI-529989; SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, centrosome. Note=Colocalizes with CEP152 in a discrete ring around the proximal end of the parental centriole. At this site, a cohesive structure is predicted to engage parental centrioles and procentrioles. DISEASE: Defects in CEP63 are the cause of Seckel syndrome type 6 (SCKL6) [MIM:614728]. A rare autosomal recessive disorder characterized by proportionate dwarfism of prenatal onset associated with low birth weight, growth retardation, severe microcephaly with a bird-headed like appearance, and mental retardation. SIMILARITY: Belongs to the CEP63 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
