摘要:
The present invention provides an extracellular anti-linker/label epitope chimeric antigen receptor (anti-LLE CAR) comprising I) a linker/label epitope (LLE) binding domain, II) a transmembrane domain, and III) a signal transduction domain, wherein said extracellular LLE binding domain binds a target cell binding molecule (TCBM) comprising i) an antigen binding moiety (ABM), wherein said ABM binds specifically to an antigen expressed on a target cell, ii) a label moiety (LaM), wherein said LaM is a naturally occurring molecule in a subject or a derivative thereof, iii) a linker moiety (LiM) conjugating said ABM and said LaM, thereby forming a linker/label epitope (LLE), wherein said extracellular LLE binding domain binds said LLE with a higher preference than said naturally occurring molecule.
摘要:
The present invention provides a composition comprising i) a polypeptide comprising calmodulin and two immunoglobulin superfamily domains, wherein said two immunoglobulin superfamily domains are linked via said calmodulin; ii) a calmodulin binding molecule; iii) ions binding to the Ca 2+ binding site of calmodulin; wherein the binding of said calmodulinbinding molecule and of said ions to said Ca 2+ binding site of calmodulin affects the binding of said polypeptide to an antigen to be bound by said polypeptide. The calmodulin may be a permutated calmodulin. A method for affecting the binding of a polypeptide for an antigen using said composition is also disclosed.
