In addition, the new receptors described herein incorporate an extracellular oligomerization domain to promote oligomer formation of the chimeric receptors. Also provided are compositions and methods useful for producing such receptors, nucleic acids encoding same, engineered cells genetically modified with the nucleic acids, as well as methods for modulating an activity of a cell and/or for the treatment of various diseases such as cancers.
