The ACTBL2 Knockout HEK293T Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population designed for loss-of-function studies of the ACTBL2 gene. This polyclonal pool, generated by CRISPR/Cas9-mediated gene disruption in HEK293T cells, provides a heterogeneous knockout model that avoids clonal artifacts while enabling robust investigation of ACTBL2 function in cellular processes. The product retains the key attributes of the HEK293T background and is suitable for a wide range of biochemical and cell-based assays.
The host cell line, HEK293T, is a derivative of the human embryonic kidney HEK293 cell line that stably expresses the SV40 large T antigen. This modification enhances episomal replication of transfected plasmids containing the SV40 origin of replication, resulting in high-level protein expression. HEK293T cells exhibit adherent epithelial morphology and are a staple in molecular and cell biology laboratories for transient transfection, viral packaging, and functional genomics applications.
ACTBL2 encodes an actin-like protein that participates in actin cytoskeleton organization and cell motility. The protein functions downstream of Rho GTPases such as RhoA, which act through ROCK and LIMK to regulate actin dynamics via cofilin phosphorylation. ACTBL2 interacts with key actin-binding partners including profilin, the ARP2/3 complex, gelsolin, and tropomyosin to facilitate actin filament polymerization and lamellipodia formation. Upstream inputs from integrin signaling, serum response factor (SRF), and TGF-beta further converge on ACTBL2 to modulate cytoskeletal rearrangements and focal adhesion turnover.
In the HEK293T context, disruption of ACTBL2 impairs actin filament dynamics, leading to reduced lamellipodia formation and diminished cell migration. These phenotypic changes are consistent with a compromised Rho GTPase signaling axis and defective cytoskeletal integrity. The polyclonal knockout model therefore provides a physiologically relevant system to dissect ACTBL2??s role in processes such as cell adhesion, proliferation, and the aggressive migratory behavior characteristic of metastatic cancer cells.
ACTBL2 Knockout HEK293T Polyclonal Cells are ideally suited for investigating actin cytoskeleton dynamics, cell migration mechanisms, and cancer cell invasion. Researchers can assess ACTBL2-dependent changes using western blotting for total actin and phospho-cofilin, immunofluorescence staining with phalloidin to visualize F-actin, transwell migration and invasion assays, live-cell imaging of actin dynamics, and wound-healing assays. This polyclonal knockout population offers a versatile and accessible tool for probing the molecular underpinnings of cytoskeletal regulation and its disruption in disease.
