Biological background
Biological context: The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors ly responsible for vesicle formation, movement, tethering and fusion. That Rab plays a role in endocytic recycling, regulating apical recycling of several transmembrane proteins including cystic fibrosis transmembrane conductance regulator/CFTR, epithelial sodium channel/ENaC, potassium voltage-gated channel, and voltage-dependent L-type calcium channel. May also regulate constitutive and regulated secretion, like insulin granule exocytosis. Required for melanosome transport and release from melanocytes. Also regulates V-ATPase intracellular transport in response to extracellular acidosis.
Expression and localization notes: cellular localization: Recycling endosome membrane, Lipid-anchor, Synaptic vesicle membrane, Phagosome membrane., tissue context: Expressed in all tissues except liver. Highest levels found in heart, skeletal muscle and pancreas..
Common research applications
- Western blotting (WB): Compare CNTN1 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of CNTN1 in tissue sections, considering fixation and antigen retrieval effects.
- Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
- Flow cytometry: Quantify CNTN1-positive populations in single-cell suspensions with appropriate gating and controls.
- ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.
Notes for experimental interpretation
- Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
- Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.
Additional product notes (from provided fields)
- Background: Contactin 1, also known as CNTN1, is a protein which in humans is encoded by the CNTN1 gene. The protein encoded by this gene is a member of the immunoglobulin superfamily. It is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Recycling endosome membrane, Lipid-anchor, Synaptic vesicle membrane, Phagosome membrane.
- Tissue details: Expressed in all tissues except liver. Highest levels found in heart, skeletal muscle and pancreas.
- Research category: Angiogenesis,Cancer,Cardiovascular,Growth Factors,Growth Factors/Hormones,Invasion/Microenvironment,Neurogenesis,Neurology Process,Neuroscience,Signal Transduction
