Mouse Rtp1 encodes receptor transporter protein 1 (RTP1), a small membrane-associated accessory factor that promotes trafficking and functional surface expression of specific G protein–coupled receptors, particularly olfactory receptors. RTP1 supports GPCR maturation, ER export, and plasma membrane localization, thereby influencing receptor-dependent signal transduction and sensory GPCR biology. By modulating receptor availability at the cell surface, RTP1 can shape downstream cAMP-linked signaling dynamics and cellular responsiveness to ligands. Dysregulation of receptor trafficking and GPCR signaling is relevant to neurobiology and sensory system studies, and RTP1 is frequently used as a tool gene in heterologous GPCR expression and deorphanization workflows.
RTP1 Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Rtp1 upregulation across a broader range of human cell types.
RTP1 Lentiviral Activation Particles (m) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the Rtp1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous RTP1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Rtp1 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
