In vivo assembly of plasmid-expressed ribosomal protein S7 of Thermus thermophilus into Escherichia coli ribosomes and conditions of its overexpression.

abstract：:In this study, we demonstrated that tissue inhibitor of metalloproteinases (TIMP) produced by human bone marrow stromal cell line KM-102 had erythroid-potentiating activity (EPA) which stimulates the proliferation of erythroid progenitor cells. We, then, propose a scheme for the bifunctional role of TIMP/EPA in hemato...

Taking advantage of this homology, a novel cDNA was cloned from pig bone marrow RNA. This encodes a 166-residue polypeptide with highly conserved pre- (29 residues) and pro- (101 residues) sequences,...
