Abstract:
We have now discovered a new method for treating carcinoembriyonic antigen (CEA) associated cancers. This involves blocking a protein expressed by the hnRNP M4 gene (preferably the human hnRNP M4 gene). We identified and isolated a liver-derived recombinant cDNA clone, termed heterogeneous nuclear RNA binding protein M4 (hnRNP M4) SEQ ID NO: 1, from rat macrophages Kupffer cells (KC) that encodes a novel protein interacting with CEA molecules and is 91% homologous with the deletion mutant of the human hnRNP M4 gene (# U32577). The novel protein is, hereinafter, considered as one protein population with the human homologue and referred to herein as hnRNP M4 CEA receptor, or hnRNP M4.
