Product Type Specific: CDK1 protein kinase pan-specific antibody
Antibody Code: NK025-7
Antibody Target Type: Pan-specific
Protein UniProt: P06493
Protein SigNET: CDK1
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human CDK1 (CDC2) sequence peptide
Antibody Immunogen Sequence: PLFHGDSEIDQLFRIFALGTPGGC
Antibody Immunogen Description: Corresponds to amino acid residues P202 to P223; in the protein kinase catalytic subdomain X region.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.
Antibody Concentration: 1 mg/ml
Storage Buffer: Phosphate buffered saline pH 7.4, 0.05% Thimerasol
Storage Conditions: For long term storage, keep frozen at -40°C or lower. Stock solution can be kept at +4°C for more than 3 months. Avoid repeated freeze-thaw cycles.
Product Use: Western blotting | Antibody microarray
Antibody Dilution Recommended: 2 µg/ml for immunoblotting
Antibody Potency: Weak immunoreactivity of a target-sized protein by Western blotting in brain, testes and thymus.
Antibody Species Reactivity: This antibody detects the target protein in the following species due to conservation of amino acid sequence: Human | Chimpanzee | Rhesus macaque | Dog | Sheep | Rat | Platypus | Chicken | Frog | Zebra fish | Fruit fly | Honey bee | Nematode worm | Sea urchin | Maize | Thale cress | Budding yeast.
Antibody Positive Control: The observed molecular mass of the processed target protein on SDS-PAGE gels is reported to be around 30-35 kDa.
Antibody Specificity: Medium
Antibody Cross Reactivity: Very strong detection of 46 kDa protein in mouse brain and 38 kDa protein in mouse skeletal muscle that may be GSK3-beta, which was also detected in various human cancer cell lines (e.g. A431, HEK-293, HepG2, Jurkat and MCF7).

Scientific Background: CDK1 (CDC2) is a 34 kDa protein-serine/threonine kinase of the CMGC group and CDK family. It plays an essential role in cell cycle control in eukaryotic cells by regulating the centrosome cycle, mitotic onset, G2-M phase transition, G1 progression, and G1-S phase transition through an association with various interphase cyclin proteins. Beyond mitosis, CDK1 regulates Golgi remodeling, vesicle transport, and is implicated in DNA damage checkpoints. Phosphorylation events at Thr-14 or Tyr-15 on CDK1 are inactivating, while phosphorylation at Thr-161 is stimulatory. It is activated by binding to cyclin B1, followed by activation via CDC25 phosphatase, which removes inhibitory phosphorylation from WEE1/MYT1 kinases. CDK1 phosphorylates over 200 proteins to trigger mitotic events like centrosome separation, nuclear envelope breakdown, and chromosome condensation. CDK1 is found in the nucleus, cytoplasm, centrosomes, and mitotic spindle. Human CDK1 shares approximately 63% amino-acid identity with yeast, allowing it to function across species. Gain-of-function mutations in the CDK1 gene have been linked to several forms of cancer, indicating an oncogenic role for the CDK1 protein. Cells transformed with the oncogene MYC undergo apoptosis when treated with small-molecule CDK1 inhibitors. Elevated expression of CDK1 has been reported as a diagnostic marker for cancer progression in esophageal adenocarcinoma, potentially reflecting the role of the CDK1 protein in tumorigenesis. CDK1 expression can be used as a prognostic indicator for early breast cancer. For example, breast cancer tumours with high expression of CDK1 are correlated with a significantly lower 5-year patient survival rate (66. 9%) than tumours that have low levels of CDK1 expression (84. 2%).
