RAB11FIP5 encodes Rab11-FIP5, a Rab11 family–interacting protein that functions as an effector in Rab11-dependent recycling endosome trafficking. By linking Rab11-positive membranes to motor and tethering machinery, Rab11-FIP5 helps coordinate cargo sorting, endocytic recycling, and membrane delivery required for polarity, cytokinesis, and receptor turnover. These processes integrate with vesicle transport networks governing signaling amplitude and membrane composition, making RAB11FIP5 a useful node for studying endosomal pathway regulation. Dysregulated endocytic recycling has been implicated in diverse disease-relevant phenotypes, including altered receptor signaling, aberrant cell migration, and changes in immune cell function.
Rab11-FIP5 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient RAB11FIP5 upregulation across a broader range of human cell types.
Rab11-FIP5 Lentiviral Activation Particles (h) 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 RAB11FIP5 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Rab11-FIP5 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native RAB11FIP5 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.
