Zimp10 CRISPR/Cas9 KO Plasmid (h): sc-407608

Overview

ZMIZ1 encodes Zimp10, a PIAS-like transcriptional co-regulator that modulates gene expression by partnering with sequence-specific transcription factors and components of the SUMOylation machinery. Zimp10 has been linked to regulation of nuclear receptor signaling, chromatin-associated transcriptional programs, and cell fate decisions, including effects on proliferation and differentiation. Through these functions, ZMIZ1 is frequently studied in pathways relevant to hematopoietic development and immune regulation, where altered transcriptional control can contribute to disease-associated gene expression states. Dysregulated ZMIZ1 activity and genetic variation have been investigated in the context of cancer biology and immune-mediated disorders, supporting its utility as a node for mechanistic studies of transcriptional networks.

Zimp10 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the ZMIZ1 gene in human cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the ZMIZ1 locus, alongside the Streptococcus pyogenes Cas9 nuclease, and encodes GFP to enable fluorescent identification and enrichment of successfully transfected cells. This multi-guide strategy increases the likelihood of inducing frameshifts or deletions that produce a functional knockout, offering a more robust alternative to single-guide approaches. DSBs induced at multiple sites are resolved through non-homologous end joining (NHEJ) or, when used with the included HDR donor template, homology-directed repair (HDR) at a defined target site within the locus.

When used in conjunction with the RFP-expressing HDR donor, GFP and RFP fluorescence can be used together to distinguish transfected from edited cell populations, streamlining flow cytometry-based sorting and clone selection workflows.

Homology-Directed Repair (HDR) Donor — Puromycin Cassette with RFP Reporter

For applications requiring confirmed, selectable knockout clones, Zimp10 HDR Plasmid (h) includes an HDR donor construct containing a puromycin resistance cassette (PuroR) and a red fluorescent protein (RFP) reporter, flanked by homology arms specific to a defined ZMIZ1 target site.
When co-transfected with Zimp10 CRISPR/Cas9 KO Plasmid (h):

• The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the ZMIZ1 open reading frame.
• RFP fluorescence provides an immediate visual indicator of successful integration, enabling fluorescence-based identification or sorting of edited cells prior to or alongside puromycin selection.
• Successfully edited cells are confirmed through puromycin resistance, substantially reducing clone screening burden.
• This selection strategy is ideal for generating stable, clonal KO cell lines for downstream functional studies, drug screening, or model development.

Cre-lox Cassette Removal System

The HDR donor construct features loxP sites flanking the PuroR-RFP selection cassette to allow clean marker removal following clone confirmation. Transient expression of Cre recombinase via the included Cre Vector: sc-418923 excises the cassette, leaving a minimal residual loxP site within the ZMIZ1 locus and eliminating potential confounding effects on downstream assays.
This two-step approach:

• Minimizes disruption to local chromatin architecture and neighboring regulatory elements
• Restores a near-native genomic context at the edited locus
• Enables reuse of the puromycin selection strategy in the same cell line for additional edits
