Abstract
The present invention relates to CD98hc binding moieties with high specificity and with ability to cross the blood brain barrier (BBB). Such moieties may be used alone or as components in specific conjugates that target the amino acid transporter complexes formed with a light chain and CD98hc. The invention relates more specifically to VNAR single chain antibodies derived from nurse shark that bind to CD98hc, compounds and compositions comprising a CD98hc-specific binding moiety, diagnostic and therapeutic methods of use in vitro or in vivo, e.g., to diagnose, treat and/or prevent a pathological condition, disorder or disease in which it is beneficial to deliver a heterologous biomolecule across the blood brain barrier by association with a CD98hc-specific VNAR binding moiety. The invention also includes Type IV semi-synthetic VNAR libraries derived from shark VNARs for selection of binding moieties that specifically bind to a molecular or cellular target of interest.
