For example, would disruption the CUL4A or DDB1 or CRBN expression of the E3 ubiquitin ligase CUL4-RBX1-DDB1-CRBN (known as CRL4(CRBN)) affect other proteins expression of this complex?
Previously when I co-coluture anti-CD19(FMC63) CAR-Jurkat with Raji with E:T=5:1, Jurkat can eliminate Raji in 24h. However, when I test another CAR construct, although I can dectect totally CD69...
