BAG-1, an important regulatory protein associates with several signaling molecules and is capable of suppressing apoptosis. A 97-amino acid segment that includes the ubiquitin homology domain of mouse BAG-1 interacts with the cytoplasmic tail domain of proHB-EGF, and this interaction is likely to have functional significance. Here we report the backbone and side-chain resonance assignments for this 97-amino acid segment of mouse BAG-1. The assignment data has been deposited in the BMRB database under the accession number 18416.
