Abstract The present invention relates to a chimeric antigen receptor (CAR) which specifically binds to CADM1, a polynucleotide encoding the CAR, a vector including the polynucleotide, a T cell or a natural killer cell (an NK cell) transformed with the vector, and a cell therapeutic agent or pharmaceutical composition for the treatment of cancer, which includes the cell as an active ingredient. The CAR of the present invention includes the extracellular domain of CRTAM, which specifically binds to CADM1. Accordingly, the cytotoxic T cells or natural killer cells transformed with a vector capable of overexpressing the CAR have specific cytotoxicity against carcinomas expressing CADM1, so the cells can be advantageously used as an immune cell therapeutic agent for cancer treatment. 본 발명은 CADM1에 특이적으로 결합하는 키메릭 항원 수용체(chimeric antigen receptor, CAR); 상기 키메릭 항원 수용체 단백질을 코딩하는 폴리 뉴클레오티드; 상기 폴리 뉴클레오티드를 포함하는 벡터; 상기 벡터로 형질전환된 T 세포 또는 자연살생세포(Natural killer cell, NK cell) 및 상기 세포를 유효성분으로 포함하는 세포 치료제 또는 암의 치료용 약학적 조성물에 관한 것이다. 본 발명에 따른 키메릭 항원 수용체는 CADM1에 특이적으로 결합하는 CRTAM의 세포외 도메인을 포함한다. 따라서, 상기 키메릭 항원 수용체를 과발현시킬 수 있는 벡터로 형질전환된 세포독성 T 세포 또는 자연살생세포의 경우 CADM1을 발현하는 암종에 특이적으로 세포독성을 갖게되므로 암 치료를 위한 면역세포 치료제로서 유용하게 이용될 수 있다.
