Sequence analysis revealed that TRK-T1 is created by an intrachromosomal rearrangement that juxtaposes the 5' end of the TPR gene to the TRK tyrosine kinase domain.     ///    TRK-T1 is a novel oncogene formed by the fusion of TPR and TRK genes in human papillary thyroid carcinomas..     ///    "In this paper we describe the isolation and characterization of one of the thyroid TRK oncogenes, designated TRK-T1. "    ///    TRK-T1 mRNA encodes a protein of 55 kDa reacting with antibodies against the carboxy terminus of the proto-TRK protein.
