The present invention is directed to a nucleic acid molecule comprising a polynucleotide sequence encoding a chimeric antigen receptor comprising (a) an anti-CLEC14A binding domain, (b) a transmembrane domain and (c) an intracellular signalling domain wherein said anti-CLEC14A binding domain is capable of binding to the C- type lectin domain of CLEC14A. The invention further provides a chimeric antigen receptor encoded by the nucleic acid molecule, a vector comprising the nucleic acid molecule, a cell comprising the nucleic acid molecule, vector or CAR and the therapeutic use of the nucleic acid, vector or cell, particularly in treating CLEC14A expressing conditions.
