The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 149 kDa (predicted molecular weight: 153 kDa).
FunctionPlays an important role in cell division and centrosome function by participating in centriole duplication. Inhibits microtubule nucleation from the centrosome.
Involvement in diseaseDefects in CENPJ are the cause of microcephaly primary type 6 (MCPH6) [MIM:608393]. A disorder defined as a head circumference more than 3 standard deviations below the age-related mean. Brain weight is markedly reduced and the cerebral cortex is disproportionately small. Despite this marked reduction in size, the gyral pattern is relatively well preserved, with no major abnormality in cortical architecture. Primary microcephaly is further defined by the absence of other syndromic features or significant neurological deficits. Defects in CENPJ are the cause of Seckel syndrome type 4 (SCKL4) [MIM:613676]. SCKL4 is 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.
Sequence similaritiesBelongs to the TCP10 family.
Post-translational modificationsPhosphorylation at Ser-589 and Ser-595 by PLK2 is required for procentriole formation and centriole elongation. Phosphorylation by PLK2 oscillates during the cell cycle: it increases at G1/S transition and decreases during the exit from mitosis. Phosphorylation at Ser-595 is also mediated by PLK4 but is not a critical step in PLK4 function in procentriole assembly.
Cellular localizationCytoplasm > cytoskeleton > centrosome. Cytoplasm > cytoskeleton > centrosome > centriole. Localized within the center of microtubule asters. During centriole biogenesis, it is concentrated within the proximal lumen of both parental centrioles and procentrioles.
