Overview
Mouse Anti-GIRK1 (Kir3.1) (extracellular) Antibody is an antibody targeting KCNJ3, G protein-activated inward rectifier potassium channel 1 Monoclonal raised in Mouse (Unconjugated). This antibody is commonly used in IC, IF, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: KCNJ3, G protein-activated inward rectifier potassium channel 1 (also reported as KCNJ3, G protein-activated inward rectifier potassium channel 1).
- Immunogen/epitope region: Extracellular loop.
- Homology note: Kir3.1 from human, rat and mouse samples (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat.
- Lot quality control (as provided): Western blot analysis.
- Conjugate/format: Unconjugated (may affect detection channel and background).
- Antibody type: Monoclonal / IgG1.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Kir3.1 (or G-protein regulated inward-rectifier K+ channel 1, GIRK1) is a member of the family of inward rectifying K+ channels. The family includes 15 members that are structurally and functionally different from the voltage-dependent K+ channels.The family's topology consists of two transmembrane domains that flank a single and highly conserved pore region with intracellular N- and C-termini. As is the case for the voltage-dependent K+ channels, the functional unit for the Kir channels is composed of four subunits that can assemble as either homo- or heterotetramers.Kir channels are characterized by a K+ efflux that is limited by depolarizing membrane potentials thus making them essential for controlling resting membrane potential and K+ homeostasis.Kir3.1 is a member of the Kir3.x subfamily that includes four members (Kir3.1- Kir3.4).
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
