Molecular cloning and expression of cDNAs for the human interleukin-2 receptor

Abstract
The human T-cell growth factor (interleukin-2) receptor was purified. cDNA [complementary DNA] corresponding to this receptor were cloned sequenced and expressed. One gene, but 2 interleukin-2 receptor mRNA which differ in their polyadenylation signals were identified. An additional cDNA that may correspond to an alternatively spliced mRNA that lacks a 216 base segment and appears to encode an altered membrane protein which cannot bind interleukin-2 was isolated.
