title: Structural analysis of a mature hst-1 protein with transforming growth factor activity.
abstract: A recombinant hst-1 protein produced in silkworm cells by a recombinant baculovirus, previously shown to be a potent mitogen for NIH3T3 cells and human endothelial cells, also stimulated anchorage-independent growth of NRK-49F cells. Amino acid sequence analysis revealed that the amino-terminal sequence with 58 amino acids was cleaved off in silkworm cells. These results indicated that the mature hst-1 protein consisting of 148 amino acids had transforming growth factor activity.
