Function

Direct ligand for the ERBB4 tyrosine kinase receptor. Binding results in ligand-stimulated tyrosine phosphorylation and activation of the receptor. Does not bind to the EGF receptor, ERBB2 or ERBB3 receptors.

Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: Highly expressed in most regions of the brain with the exception of corpus callosum. Expressed at lower level in testis. Not detected in heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, ovary, small intestine, colon and peripheral blood leukocytes

Product Specifications

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.
