Function

ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning for the initiator codon.

Biological Context

Disease Association: Neurodevelopmental disorder with hypotonia and speech delay, with or without seizures (NEDHSS) : A disorder characterized by global developmental delay, intellectual disability, poor or absent speech, hypotonia, epilepsy, and structural brain anomalies. Inheritance is autosomal dominant or autosomal recessive. [The disease is caused by variants affecting the gene represented in this entry]

Product Specifications

Recombinant Human Eukaryotic initiation factor 4A-II (EIF4A2) is a recombinant protein from Homo sapiens (Human), expressed in E.coli, covering amino acids 1-407aa, with N-terminal GST-tagged tag, molecular weight 73.4kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

Frequently Asked Questions

How do I order or inquire about this product?

Fill out the Online Inquiry form with your required quantity and specifications. You can also email sales@biocrestsci.com. Our team typically responds within 4 business hours with a quote and availability confirmation.

What is the shipping and delivery time?

Orders placed before 2 PM EST ship the same day. Domestic (US) delivery typically takes 2-3 business days. International orders deliver within 5-10 business days. All products are shipped at ambient temperature with appropriate packaging to ensure stability.

How should I store this recombinant protein?

Lyophilized proteins should be stored at -20°C to -80°C upon receipt. After reconstitution, aliquot and store at -80°C. Avoid repeated freeze-thaw cycles. Shelf life is 12 months from date of receipt when stored as recommended.

What quality controls are performed on your products?

Each product undergoes SDS-PAGE purity analysis (typically >85-95%), endotoxin testing, and bioactivity validation. Products are validated for ELISA, Western Blot, and SPR/BLI applications as specified on this product page. A Certificate of Analysis (CoA) is available upon request.
