  • 蛋白结构(Molecular Characterization)

    WEE1 Structure

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 51.1 kDa. The protein migrates as 8 kDa,30-33 kDa and 55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 纯度(Purity)

    >80% as determined by SDS-PAGE.

  • 制剂(Formulation)

    Supplied as 0.2 μm filtered solution in 50 mM Tris, 300 mM NaCl, pH7.5 with glycerol as protectant.

  • 电泳(SDS-PAGE)

    WEE1 SDS-PAGE

    Human WEE1 Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 80% (With Star Ribbon Pre-stained Protein Marker).

  • 活性(Bioactivity)

    The WEE1 assay is performed using the ADP-Glo TM Kinase Assay kit which quantifies the amount of ADP produced by the WEE1 reaction. The ADP- Glo TM Reagent is added to terminate the kinase reaction and to deplete the remaining ATP, and then the Kinase Detection Reagent is added to convert ADP to ATP and to measure the newly synthesized ATP using luciferase/luciferin reaction. The specific activity is >10 pmol/min/μg (QC tested).

背景介绍

WEE1​​ is a ​​serine/threonine protein kinase​​ that acts as a ​​critical regulator of the cell cycle​​, particularly at the ​​G₂/M checkpoint​​. It inhibits cell cycle progression by phosphorylating and inactivating ​​CDK1​​ (Cyclin-Dependent Kinase 1) at Tyr15, thereby preventing premature entry into mitosis and allowing time for DNA repair.Originally identified in fission yeast, WEE1 is highly conserved in mammals and plays a key role in maintaining genomic stability. Dysregulation of WEE1 is linked to ​​cancer progression​​, as its overexpression in tumors (e.g., ovarian, breast, pancreatic cancers) supports cancer cell survival by enabling DNA damage tolerance. This dependency makes WEE1 a ​​promising therapeutic target​​, especially in p53-mutant cancers where inhibiting WEE1 induces synthetic lethality by forcing cells with unrepaired DNA into catastrophic mitosis.
