Possesses microtubule stabilizing properties. Involved in regulating aneuploidy, cell cycling, and cell death in a p53/TP53-dependent manner.
Abundant in testis, thymus, and in tumor derived cell lines, while barely detectable in liver, prostate, and kidney.
Belongs to the CKAP2 family.
Present 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).
Cytoplasm > 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.
