FunctionPossesses microtubule stabilizing properties. Involved in regulating aneuploidy, cell cycling, and cell death in a p53/TP53-dependent manner.
Tissue specificityAbundant in testis, thymus, and in tumor derived cell lines, while barely detectable in liver, prostate, and kidney.
Sequence similaritiesBelongs to the CKAP2 family.
Developmental stagePresent at the G1/S boundary. Accumulates as cells progress from S to G2 into mitosis. Rapidly degraded during mitosis exit by CDH1-activated anaphase promoting complex/cyclosome (APC/C).
Cellular localizationCytoplasm > cytoskeleton. Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > spindle. Cytoplasm > cytoskeleton > spindle pole. Contrary to the ectopically expressed protein, endogenous CKAP2 does not colocalize with microtubules in G1, S and early G2. At late G2 and prophase after separation of duplicated centrosomes, colocalizes with gamma-tubulin and centrosome-proximal microtubules. From prometaphase through anaphase B, colocalizes with mitotic spindle poles and spindle microtubules. During cytokinesis, absent from midbody microtubules.
