The KTN1 Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from the HeLa human cervical adenocarcinoma line. This product offers a loss-of-function model for KTN1, encoding kinectin, a kinesin-binding protein essential for organelle transport and ER architecture. The polyclonal format ensures genetic diversity while disrupting KTN1 across the population, enabling sustained functional studies without transient suppression.
The HeLa host is an immortalized HPV18-positive epithelial tumor line from cervical adenocarcinoma, widely used in cancer and cell biology. Its robust growth and well-characterized signaling make it ideal for studying cytoskeletal dynamics, migration, and organelle organization. In this knockout context, HeLa cells enable analysis of how ER tubulation and kinesin-mediated transport affect tumor cell behavior.
KTN1 serves as a scaffold linking kinesin-1 (KIF5B) to cargoes, driving ER tubule extension along microtubules. It interacts with ER membrane proteins CLIMP-63 and RTN4, and Rab18, to regulate organelle positioning. Upstream, KTN1 is modulated by integrin signaling, Src-family kinases, and the unfolded protein response. Downstream, it influences kinesin-1 binding, ER protein distribution, and focal adhesion components like paxillin, thereby integrating ER morphology with adhesion and migration.
In HeLa cervical adenocarcinoma cells, KTN1 disruption is pertinent to cancer metastasis research. KTN1 has implications in ovarian and hepatocellular carcinoma, and its role in focal adhesion dynamics suggests knockout cells may display altered motility and invasion. This polyclonal pool allows population-level phenotypic analysis while reducing clonal artifacts, facilitating studies linking ER network organization to oncogenic signaling and metastatic potential.
Applications include ER morphology assessment via immunofluorescence, organelle transport analysis via live-cell imaging, and knockout validation by Western blotting or RT-qPCR. Migration/invasion assays, wound healing, and kinesin-1 co-immunoprecipitation can probe KTN1??s role in motility and motor coupling. This model also supports spastic paraplegia and therapeutic target studies. For technical inquiries, contact Ascent Research.
