The UniProt recommended name is Ras-related protein Rab-1A (RAB1A). This essential member of the Rab family regulates the formation, movement, and docking of transport vesicles that ensure protein secretion and Golgi organization.\u003cbr\u003e\u003cbr\u003eFunctionally, RAB1A antibody identifies a 205-amino-acid GTP-binding protein that cycles between active GTP-bound and inactive GDP-bound states. Active RAB1A recruits effector proteins such as p115, GM130, and COPII components to mediate vesicle tethering and fusion at the cis-Golgi membrane. It coordinates early secretory pathway events and maintains ER-to-Golgi transport fidelity, supporting proper protein maturation and trafficking.\u003cbr\u003e\u003cbr\u003eThe RAB1A gene is located on chromosome 2p14 and is ubiquitously expressed in eukaryotic cells, with particularly high expression in secretory tissues. Its activity is regulated by GEFs (guanine nucleotide exchange factors) and GAPs (GTPase-activating proteins) that control the GTP\/GDP cycle and subcellular localization.\u003cbr\u003e\u003cbr\u003ePathologically, RAB1A dysregulation affects autophagy, neurodegeneration, and cancer progression. Overexpression enhances cell proliferation and Golgi reorganization in tumor cells, while impaired RAB1A function contributes to ER stress and defective autophagosome formation. Research using RAB1A antibody supports studies in membrane trafficking, Golgi function, and oncogenic signaling.\u003cbr\u003e\u003cbr\u003eRAB1A antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect small GTPases. \u003cbr\u003e\u003cbr\u003eStructurally, Ras-related protein Rab-1A contains conserved GTP-binding motifs (GxxxxGK[S\/T], DxxG, NKxD, and SAx) and a C-terminal geranylgeranylation site that anchors it to membranes. Its switch regions undergo conformational changes upon GTP binding, enabling interaction with effectors that mediate vesicle transport. This antibody allows exploration of RAB1A's role in ER-Golgi trafficking and its contribution to secretory pathway regulation.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=RAB1A - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=RAB1A - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=RAB1A - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/RAB1A - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=RAB1A+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047319069037,"sku":"FY13241","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_17bb894d-160c-4295-a0f3-48abe6a06cbb.jpg?v=1782237081","url":"https:\/\/www.ebiohippo.com\/products\/rab1a-antibody-ras-related-protein-rab-1a-bha17136143","provider":"BioHippo","version":"1.0","type":"link"}
