High-depth sequencing to identify pathogenic SNPs and Indels across the 50+ exons of the ANK2 gene, critical for diagnosing cardiac and neurological syndromes.
Creative Biolabs' expert team utilizes a high-throughput, precision-driven platform to provide comprehensive ankyrin-B (ANK2) analysis. Our services offer a variety of strategies and readout options, helping clients gain an additional layer of information through assay setups tailored to specific research needs.
Introduction of ANK2
The ANK2 gene encodes ankyrin-B, a critical scaffolding protein that anchors integral membrane proteins, such as ion channels and transporters, to the spectrin-actin cytoskeleton. This structural linkage is essential for cellular stability and signaling, and its disruption is a known driver in the etiology of autism spectrum disorders (ASD), where ANK2 acts as a high-confidence candidate gene. Beyond neurology, ANK2 serves as a versatile oncological biomarker; while its downregulation in colorectal and thyroid cancers suggests tumor-suppressive properties, its mutation or elevated expression in advanced lung adenocarcinoma (LUAD) correlates with enhanced efficacy of immune checkpoint inhibitors. Consequently, precise ANK2 analysis is vital for advancing both neurodevelopmental research and personalized cancer immunotherapy.

Applications
Neurodevelopmental Research
Analysis of ANK2 variants provides critical insights into the molecular pathology of non-syndromic autism. Quantifying the giant 440 kDa isoform helps researchers understand how disrupted microtubule bundling leads to the ectopic axonal branching characteristic of ASD phenotypes.
Cardiac Electrophysiology
Mapping ANK2 mutations is essential for identifying the underlying cause of Type 4 Long QT Syndrome. Evaluating the stability of the ankyrin-B/NCX1/Na+/K+ ATPase complex allows for the characterization of calcium-dependent arrhythmias and sinus node dysfunction.
Immunotherapy Stratification
Assessing ANK2 mutational status in lung adenocarcinoma serves as a predictive tool for immune checkpoint inhibitor (ICI) response. High tumor mutational burden involving ANK2 often correlates with improved clinical outcomes and prolonged progression-free survival in patients.
Metabolic Syndrome Studies
Investigation into the ankyrin-B/GLUT4 pathway reveals the genetic basis of impaired glucose transport. Analysis of ANK2 expression in adipose and muscular tissues assists in identifying susceptibility markers for Type 2 Diabetes and related metabolic imbalances.
Oncology Prognostics
Monitoring the downregulation of ANK2 mRNA in colorectal and thyroid malignancies serves as a prognostic indicator. Reduced scaffolding activity often mirrors the loss of cell-cell adhesion, providing a metric for assessing metastatic potential and tumor grade.

FAQs
-
Q: Which starting materials are most suitable for ANK2 expression analysis?
A: For protein-level detection, fresh-frozen tissue or cell pellets are preferred to maintain the integrity of the large ankyrin-B protein. For mRNA studies, RNA-stabilized samples or high-quality total RNA are sufficient to provide accurate quantitative PCR or RNA-Seq results.
-
Q: Can your platform distinguish between the different isoforms of ANK2?
A: Yes, our specialized primers and antibodies are designed to target the neurospecific domain unique to the 440 kDa giant isoform. This allows for precise quantification of the brain-specific variant versus the more common 220 kDa isoform found in the heart.
-
Q: How do you handle the high polymorphism rate of the ANK2 gene during analysis?
A: We utilize a proprietary bioinformatic pipeline that cross-references identified variants against extensive databases of healthy controls and known pathogenic cohorts. This allows us to accurately filter out benign polymorphisms and focus on clinically significant mutations.
-
Q: Is it possible to develop a custom ELISA specifically for my target ANK2 domain?
A: Our team can produce custom monoclonal or polyclonal antibodies against specific peptides or recombinant domains of ankyrin-B. These are then validated for sensitivity and specificity within a sandwich or indirect ELISA format tailored to your research.
-
Q: How do you ensure the stability of the large ANKB protein during Western Blotting?
A: Due to the high molecular weight of the 440 kDa isoform, we employ specialized high-porosity gels and optimized transfer buffers. These modifications ensure that even the largest isoforms are successfully separated and transferred for accurate immunodetection.
-
Q: Can ANK2 analysis be used to predict drug-induced cardiotoxicity?
A: Investigating the interaction between a candidate compound and the ankyrin-B scaffolding complex can reveal indirect cardiotoxic effects. If a drug interferes with ANK2-mediated channel anchoring, it may lead to arrhythmias, making this analysis a valuable safety screen.
