Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the C-terminus of human RALB, different from the related mouse sequence by three amino acids, and from the related rat sequence by four amino acids.
• Molecular weight context: reported MW: 23 kDa; calculated MW: 23409 MW
• Reactivity: Human,Mouse,Rat
• Applications: Flow Cytometry, IF, 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

Ras-related protein Ral-B; Ras-related protein Ral-B. Ras-related protein Ral-B (RalB) is a protein that in humans is encoded by the RALB gene on chromosome 2. This protein is one of two isoforms of the Ral protein, the other being RalA, and part of the Ras GTPase family. As a Ras GTPase, RalB functions as a molecular switch that becomes active when bound to GTP and inactive when bound to GDP. RalB can be activated by RalGEFs and, in turn, activate effectors in signal transduction pathways leading to biological outcomes. Additionally, Ral proteins have been associated with the progression of several cancers, including bladder cancer and prostate cancer. While the above functions appear to be shared between the two Ral isoforms, their differential subcellular localizations result in their differing involvement in certain biological processes. In particular, RalB is more involved in apoptosis and cell motility. Moreover, RalB specifically interacts with Exo84 to assemble the beclin-1–VPS34 autophagy initiation complex, and with Sec5 to activate the innate immune response via the Tank-binding kinase 1 (TBK1). Functional note: Multifunctional GTPase involved in a variety of cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Accomplishes its multiple functions by interacting with distinct downstream effectors. Acts as a GTP sensor for GTP-dependent exocytosis of dense core vesicles. Required both to stabilize the assembly of the exocyst complex and to localize functional exocyst complexes to the leading edge of migrating cells. Plays a role in the late stages of cytokinesis and is required for the abscission of the bridge joining the sister cells emerging from mitosis. Required for suppression of apoptosis. . Reported localization: Cell membrane ; Lipid-anchor ; Cytoplasmic side . During late cytokinesis localizes at the midbody. Expression/tissue context: Cells of the B- and T-lymphocyte lineages.

Research relevance and current trends

• Small G Proteins: Researchers commonly examine how RALB (Ras-related protein Ral-B) relates to this theme using model systems and orthogonal readouts.

Common research applications

• Western blotting: compare relative RALB (Ras-related protein Ral-B) levels across conditions; band patterns may reflect isoforms and processing.
• 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.

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.
