-
CKAP2 acts as a functional oncogene in cervical carcinoma development and may exert its function by targeting FAK-ERK2 signaling pathway.
-
Knockdown of CKAP2 expression effectively suppressed the proliferation and induced the apoptosis by inhibiting the phosphorylation of JAK2/STAT3 of osteosarcoma cells.
-
High CKAP2 expression is associated with highgrade glioma.
-
High CKAP2 expression is associated with Ovarian Cancer.
-
Chromatin CKAP2 is an independent prognostic marker for relapse-free survival in early-stage breast cancer, and could potentially replace the mitotic activity index in clinical evaluation of proliferation activity.
-
The transcriptional activity of RHOA, SEMA3B, and CKAP2 genes was assessed in blood samples of leukaemia patients and healthy donors.
-
expression might be a potential biologic marker for identifying hepatocellular carcinoma patients at risk of early and extensive recurrence after operative resection
-
CKAP2 is involved in the maintenance of microtubule nucleation sites
-
GC box was responsible for the cyclic activity of human CKAP2 promoter through the phosphorylation of Sp1, possibly by Cyclin A/Cdk complex.
-
Findings suggest that the motif surrounding Ser627 ((625) RRSRRL (630)) is a critical for kinase-substrate recognition and for regulation of the subcellular localization of TMAP during mitosis.
-
TMAP is limited to pre-anaphase stages and suggest that the multiple phosphorylation may not act in concert but serve diverse functions.
-
CKAP2 comprises nine exons ranging 70-1442 bp and is about 22 kb in size (regulatory regions included). The CKAP2 promoter contains CCAAT (-39...-33) rather than the canonical TATA box, and harbors nine binding sites for six transcription factors
-
protein is expressed cell cycle dependently and it is involved in cell proliferation
-
Data show that degradation of TMAP/CKAP2 during mitotic exit is mediated by the anaphase-promoting complex bound to Cdh1 and that the KEN box motif near the N terminus is necessary for its destruction.
-
CKAP2 is a physiological substrate of anaphase-promoting complex/cyclosome during mitotic exit and that a tight regulation of the CKAP2 protein level is critical for the normal mitotic progression.
-
Cdk1-cyclin B1-mediated phosphorylation of TMAP is important for and contributes to proper regulation of microtubule dynamics and establishment of functional bipolar spindles during mitosis
