| abstract |
The presently disclosed subject matter relates to antibodies, antibody fragments or derivatives thereof, which specifically bind to and/or interact with at least one epitope of the extracellular domain of the mammalian KCNK9 potassium channel, and to nucleic acid molecules encoding the same, as well as to vectors comprising said nucleic acid molecules. The presently disclosed subject matter provides methods for the preparation of said antibodies, antibody fragments or derivatives thereof, as well as pharmaceutical compositions, diagnostic compositions, and kits comprising the same. Compositions, kits, methods, and uses of the antibodies, antibody fragments or derivatives thereof for assessing for the presence of KCNK9 expressing cells, inhibiting KCNK9 activity in cells, inhibiting the growth or survival of KCNK9 expressing cells (e.g., cancer cells), inhibiting the growth and/or metastases of tumors, stimulating complement-dependent cancer cell cytotoxicity, and the treatment of cancer are also provided. |
