Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E. coli-derived human RP2 recombinant protein (Position: D244-M348). (reported region: D244-M348).
• Molecular weight context: reported MW: 40 kDa; calculated MW: nan
• Reactivity: Human,Mouse,Rat
• Applications: ELISA, Flow Cytometry, IF, IHC, ICC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

RP2, ARL3 GTPase activating protein. Protein XRP2 is a protein that in humans is encoded by the RP2 gene. It is mapped to Xp11.3. The RP2 locus has been implicated as one cause of X-linked retinitis pigmentosa. The predicted gene product shows homology with human cofactor C, a protein involved in the ultimate step of beta-tubulin folding. Progressive retinal degeneration may therefore be due to the accumulation of incorrectly folded photoreceptor or neuron-specific tubulin isoforms followed by progressive cell death. The RP2 protein is also involved in regulating the function and extension of outer segment of cone photoreceptors in mice. Functional note: Acts as a GTPase-activating protein (GAP) involved in trafficking between the Golgi and the ciliary membrane. Involved in localization of proteins, such as NPHP3, to the cilium membrane by inducing hydrolysis of GTP ARL3, leading to the release of UNC119 (or UNC119B). Acts as a GTPase-activating protein (GAP) for tubulin in concert with tubulin-specific chaperone C, but does not enhance tubulin heterodimerization. Acts as guanine nucleotide dissociation inhibitor towards ADP-ribosylation factor-like proteins. Reported localization: Cell membrane. Expression/tissue context: Ubiquitous. Expressed in the rod and cone photoreceptors, extending from the tips of the outer segment (OS) through the inner segment (IS) and outer nuclear layer (ONL) and into the synaptic terminals of the outer plexiform layer (ONL). Also detected in the bipolar, horizontal and amacrine cells in the inner nuclear layer (INL), extending to the inner plexiform layer (IPL) and though the ganglion cell layer (GCL) and into the nerve fiber layer (NFL) (at protein level).

Research relevance and current trends

• Neuroscience: Researchers commonly examine how RP2 relates to this theme using model systems and orthogonal readouts.
• Sensory System: Researchers commonly examine how RP2 relates to this theme using model systems and orthogonal readouts.
• Visual System: Researchers commonly examine how RP2 relates to this theme using model systems and orthogonal readouts.

Common research applications

• Western blotting: compare relative RP2 levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of RP2 across tissue regions and cell types using matched controls.
• IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
• ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
