The KCTD6 Knockout HEK293T Polyclonal Cells are a targeted loss-of-function model generated by CRISPR/Cas9-mediated disruption of the endogenous KCTD6 gene in HEK293T cells. This polyclonal population consists of heterogeneous editing events that collectively abolish KCTD6 protein expression, offering a robust system for studying the functions of this Cullin3 adaptor. The polyclonal format avoids clonal bottlenecks and preserves biological complexity, enabling versatile applications in ubiquitin-proteasome research and signal transduction.
HEK293T is a human embryonic kidney cell line stably expressing the SV40 large T-antigen, which permits episomal replication of plasmids containing the SV40 origin. Its epithelial-like morphology, rapid doubling time, and high transfection efficiency have established HEK293T as a premier host for recombinant protein production, lentiviral packaging, and CRISPR-based genome manipulation. These features make it an ideal background for generating KCTD6 knockout pools suitable for biochemical dissection and pharmacological screening.
KCTD6 functions as a substrate adaptor for the Cullin3-RING E3 ubiquitin ligase, which ubiquitinates the histone deacetylase HDAC1 for proteasomal degradation. This targeted proteolysis controls HDAC1 protein levels and consequently modulates Wnt/??-catenin signaling through effects on DVL and ??-catenin stability. KCTD6 interacts with Cullin3 and RBX1, and its activity is regulated by Cullin3 neddylation. It also associates with GABAB receptor subunits, implicating it in GPCR signaling pathways. Thus, KCTD6 integrates protein quality control with key signal transduction networks.
In the HEK293T background, KCTD6 knockout likely stabilizes HDAC1, altering histone acetylation and gene expression programs relevant to cancer and neurodevelopment. This model enables investigation of HDAC1 degradation dynamics, cullin-RING ligase function, and cross-talk between Wnt and GPCR signaling. Its utility extends to drug screening for modulators of the ubiquitin-proteasome system and HDAC-related pathways.
Researchers can apply this polyclonal knockout to a variety of assays, including in vitro ubiquitination and proteasome inhibition experiments, co-immunoprecipitation coupled with Western blotting for interaction and degradation studies, RT-qPCR for transcriptional readouts, and Wnt-responsive luciferase reporter assays. High-throughput screening and interactome mapping are also feasible. For ordering or technical inquiries, please contact Ascent Research.
