The human TRIP-1 (transforming growth factor-β (TGBβ)-receptor interacting protein-l) cDNA encodes a protein able to associate specifically with the type II TGFβ receptor. It is phosphorylated on serine and threonine by this receptor kinase which makes it a strong candidate as part of the TGFβ signal transduction pathway. We have isolated the genomic sequence of TRIP-1 and found that the complete coding region is organised into 11 exons ranging from 39 to 397 bp and spanning approximately 9 kb of genomic DNA. The 5' flanking region lacks a TATA box but is GC-rich, suggesting that it is a constitutively expressed gene which is in agreement with its wide pattern of expression. Fluorescence in situ hybridisation mapped the TRIP-1 gene to chromosome 1p34.1 whereas a pseudogene is located on chromosome 7q32.
