Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Multidomain scaffolding protein with a role in synaptic transmembrane protein anchoring and ion channel trafficking. Contributes to neural development and regulation of gene expression via interaction with the transcription factor TBR1. Binds to cell-surface proteins, including amyloid precursor protein, neurexins and syndecans. May mediate a link between the extracellular matrix and the actin cytoskeleton via its interaction with syndecan and with the actin/spectrin-binding protein 4.1. Component of the LIN-10-LIN-2-LIN-7 complex, which associates with the motor protein KIF17 to transport vesicles containing N-methyl-D-aspartate (NMDA) receptor subunit NR2B along microtubules.
Gene References into Functions
  1. Data suggest that children with heterozygous mutation in the gene CASK kinase (CASK) and mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH) are responsive to intensive therapy aimed at increasing functional skills/independence. PMID: 29258560
  2. Authors have identified mutations in PAK3, CASK, and MECP2 that likely contribute to intellectual disability, and the findings extend the spectrum of mutations and phenotypes associated with X-linked intellectual disability. PMID: 28481730
  3. The CASK as a novel regulator of Cav1.2 via a modulation of the voltage-gated calcium channel Cav1.2 open probability. PMID: 27720444
  4. findings demonstrate that microcephaly with pontine and cerebellar hypoplasia (MICPCH) is a genetically heterogeneous condition, in which CASK inactivating mutations appear to account for the majority of MICPCH cases and with severer phenotypes, while the non-CASK mutation cases tend to have milder microcephaly PMID: 28783747
  5. we provide a further characterization of genotype-phenotype correlations in CASK mutations and the presentation of nystagmus and the FGS4 phenotype. PMID: 28139025

  7. we report a patient presenting with a complex phenotype consisting of severe, adult-onset, dilated cardiomyopathy, hearing loss and developmental delay, in which exome sequencing revealed two genetic variants that are inherited from a healthy mother: a novel missense variant in the CASK gene, mutations in which cause a spectrum of neurocognitive manifestations PMID: 27173948
  8. In clinical specimens, CASK was over-expressed in tumors and H. pylori positive tissues, and its mRNA levels were inversely correlated with miR-203 expression. PMID: 25373785
  9. Data indicate that patients with low calcium/calmodulin-dependent serine protein kinase (CASK) staining had a significantly better survival compared to patients with high CASK staining. PMID: 24927672
