The NPM sequences contained in the shorter NPM-RAR cDNA are identical to the NPM sequences contained in the NPM-ALK fusion gene expressed in t(2;5) lymphomas.     ///    "Both NPM-RAR transcripts fuse NPM and RARA sequence in the same reading frame, to generate translation products of 57 kD and 62 kD. "    ///    "In transcriptional assays using a retinoic acid response element reporter construct, both NPM-RAR fusion proteins act as retinoic acid-dependent transcriptional activators. "
