TMEM45A CRISPR Activation Plasmid (h): sc-412437-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- TMEM45A CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- TMEM45A CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by TMEM45A CRISPR Activation Plasmid (h) and TMEM45A CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the TMEM45A transcriptional start site. One or both designs may be available

TMEM45A encodes a multi-pass transmembrane protein implicated in epithelial differentiation and cellular adaptation to microenvironmental stress, with reported enrichment in hypoxic and keratinizing tissues. TMEM45A has been associated with regulation of membrane trafficking and stress-response programs that influence proliferation, survival, and barrier-related processes. Transcriptional changes in TMEM45A have been observed across multiple tumor types, supporting its use as a marker-linked gene in studies of hypoxia-driven remodeling and treatment response pathways. As a membrane-localized factor with context-dependent expression, TMEM45A is frequently investigated for its contribution to tumor cell plasticity and phenotypic heterogeneity.
TMEM45A CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TMEM45A expression without altering the underlying DNA sequence.
TMEM45A CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TMEM45A locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the TMEM45A transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous TMEM45A expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TMEM45A locus and enabling the study of TMEM45A-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of TMEM45A pathway restoration in tumor cells with silenced or reduced TMEM45A expression.
