Description

RAN (Ras-related nuclear protein) serves as a master regulator of nucleocytoplasmic transport, playing essential roles in nuclear envelope assembly, mitotic spindle organization, and post-mitotic nuclear reformation. This small GTPase cycles between GTP- and GDP-bound states to establish the gradient that drives nuclear import and export, making it fundamental to cell cycle progression and chromosome segregation. Dysregulation of RAN has been implicated in various cancers, positioning it as a significant target for researchers investigating cell division, nuclear transport mechanisms, and oncogenic pathways.

This recombinant monoclonal antibody, generated against a synthetic peptide derived from human RAN, offers the reproducibility and consistency that demanding experimental workflows require. As a sequence-defined recombinant clone, it eliminates the lot-to-lot variability inherent in traditional hybridoma-derived antibodies, ensuring your results remain comparable across extended studies and collaborative projects.

Validation across multiple platforms demonstrates genuine experimental flexibility. Immunohistochemistry studies in paraffin-embedded human testis tissue reveal clear target detection using standard citrate buffer antigen retrieval protocols at dilutions of 1:50–1:200. Immunofluorescence analysis in HeLa cells shows distinct staining patterns when counterstained with DAPI, while flow cytometry validation in the same cell line confirms robust detection with clear separation from isotype control, as demonstrated in overlay histogram analysis.

Whether you are investigating nuclear transport dynamics, characterizing mitotic machinery, or exploring RAN's documented role as an androgen receptor-associated protein in hormone-responsive contexts, this antibody provides a reliable tool for advancing your research across immunohistochemical, immunofluorescent, and flow cytometric applications.

Target Background

Function

GTPase involved in nucleocytoplasmic transport, participating both to the import and the export from the nucleus of proteins and RNAs. Switches between a cytoplasmic GDP- and a nuclear GTP-bound state by nucleotide exchange and GTP hydrolysis. Nuclear import receptors such as importin beta bind their substrates only in the absence of GTP-bound RAN and release them upon direct interaction with GTP-bound RAN, while export receptors behave in the opposite way. Thereby, RAN controls cargo loading and release by transport receptors in the proper compartment and ensures the directionality of the transport. Interaction with RANBP1 induces a conformation change in the complex formed by XPO1 and RAN that triggers the release of the nuclear export signal of cargo proteins. RAN (GTP-bound form) triggers microtubule assembly at mitotic chromosomes and is required for normal mitotic spindle assembly and chromosome segregation. Required for normal progress through mitosis. The complex with BIRC5/survivin plays a role in mitotic spindle formation by serving as a physical scaffold to help deliver the RAN effector molecule TPX2 to microtubules. Acts as a negative regulator of the kinase activity of VRK1 and VRK2. Enhances AR-mediated transactivation. Transactivation decreases as the poly-Gln length within AR increases.
