- 目标基因介绍: Cytosolic phosphoenolpyruvate carboxykinase that catalyzes the reversible decarboxylation and phosphorylation of oxaloacetate (OAA) and acts as the rate-limiting enzyme in gluconeogenesis (PubMed:11792850, PubMed:11916968, PubMed:29230018, PubMed:30193097). Regulates cataplerosis and anaplerosis, the processes that control the levels of metabolic intermediates in the citric acid cycle (PubMed:30193097). At low glucose levels, it catalyzes the cataplerotic conversion of oxaloacetate to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle (PubMed:30193097). At high glucose levels, it catalyzes the anaplerotic conversion of phosphoenolpyruvate to oxaloacetate (PubMed:30193097). Acts as a regulator of formation and maintenance of memory CD8+ T-cells: up-regulated in these cells, where it generates phosphoenolpyruvate, via gluconeogenesis (PubMed:29230018). The resultant phosphoenolpyruvate flows to glycogen and pentose phosphate pathway, which is essential for memory CD8+ T-cells homeostasis (PubMed:29230018). In addition to the phosphoenolpyruvate carboxykinase activity, also acts as a protein kinase when phosphorylated at Ser-90: phosphorylation at Ser-90 by AKT1 reduces the binding affinity to oxaloacetate and promotes an atypical serine protein kinase activity using GTP as donor (By similarity). The protein kinase activity regulates lipogenesis: upon phosphorylation at Ser-90, translocates to the endoplasmic reticulum and catalyzes phosphorylation of INSIG proteins (INSIG1 and INSIG2), thereby disrupting the interaction between INSIG proteins and SCAP and promoting nuclear translocation of SREBP proteins (SREBF1/SREBP1 or SREBF2/SREBP2) and subsequent transcription of downstream lipogenesis-related genes (By similarity).
- 细胞开发路径: A stable KO cell pool was generated using the CRISPR‑RNP approach; Sanger sequencing confirmed 100% knockout efficiency in the cell pool.
- 应用: A gene knockout cell pool with high knockout efficiency (KO Cell Pool) is particularly well suited for preliminary functional analyses, the development of complex disease models, precision drug screening, and broad‑scale gene discovery studies. The KO pool can be directly applied to a variety of assays and analyses without the need for time‑consuming single‑clone selection, significantly enhancing experimental throughput.

01. Preheat the complete culture medium in a 37°C water bath.
02. Thaw the cryovial in a 37°C water bath for 1–2 minutes.
03. Transfer the cryovials into a biosafety cabinet and wipe their surfaces with 70% ethanol.
04. Unscrew the cap of the cryovial and gently transfer the cell suspension into a sterile centrifuge tube containing 9 mL of complete culture medium.
05. Centrifuge at room temperature at 125g for 5–7 minutes, then discard the supernatant.
06. Resuspend the cell pellet in 5 mL of complete culture medium, and transfer the cell suspension to a T25 culture flask.
07. Transfer the cells to a 37°C incubator with 5% CO2 for culture.
08. Recommended passage ratio: 1/6 to 1/8; cells reach confluence in 2–3 days. -
01. When the cells in the culture flask reach a confluence of 80%–90% or higher, cell passage can be performed.
02. Remove the culture medium, PBS, and trypsin (0.25% Trypsin‑EDTA, Gibco 25200‑056) from the 4°C refrigerator, place them in a 37°C water bath, and once their temperature approaches 37°C, take them out. Spray the exterior of the bottles with 75% ethanol, then transfer them to a biosafety cabinet.03. Remove the culture flask to be passaged from the incubator, spray the exterior of the flask with 75% ethanol, and place it inside a biosafety cabinet.
04. To avoid dispersing the cells, gently rinse the cells along the inner wall of the culture flask with PBS; discard the wash solution, and add 2 mL of PBS to the T25 flask.
05. Add the appropriate volume of trypsin (1.5 mL for a T75 flask, 0.5 mL for a T25 flask), and gently swirl the flask to ensure the enzyme evenly covers the cell‑covered bottom. Adjust the volume as needed based on the specific situation. After approximately 1–2 minutes, when most of the cells have detached, add the corresponding volume of complete culture medium to stop the digestion, then use a 5‑mL pipette to gently pipette up and down until all cells are fully detached.
06. Transfer the cell suspension to a 15 mL centrifuge tube, centrifuge at 300 × g for 5 minutes, and discard the supernatant.
07. Transfer 5 mL of complete culture medium to resuspend the cells, adjust the seeding ratio as needed, and replenish the culture flask with complete medium—add up to 13–15 mL for a T75 flask and 5 mL for a T25 flask—then supplement with 1% double antibiotic solution.
08. After capping the bottle and tightening the lid, gently shake the vial to ensure uniform mixing of the cells, then place it in a 37°C incubator with 5% CO2. -
01. Prepare the cryopreservation solution and pre-cool it in advance.
02. Ensure that the cells to be cryopreserved meet the cryopreservation requirements, and verify the following conditions under a microscope: healthy appearance and morphological characteristics, being in the late logarithmic growth phase, and showing no signs of contamination or senescence.
03. Digest and centrifuge the cells (refer to the subculture protocol for detailed steps).
04. Resuspend the cells in cryopreservation medium at 1 mL per tube, gently pipette up and down to ensure uniformity, then aliquot into cryovials.
05. Place the cells in a programmed cooling box and freeze them at −80°C.
06. Subsequently, the cells are transferred to a liquid nitrogen tank for long-term storage. - In antibody validation
