The mRNA coding for rat intestinal calcium-binding protein, a vitamin D3-induced protein (M(r) 7500), has been partially purified from growing rat duodenum. Double-stranded DNA synthesized from the purified mRNA preparation was inserted into the PstI site of pBR322, using the oligo(dG-dC) tailing procedure. Clones containing DNA complementary to vitamin D-dependent calcium-binding protein mRNA were selected by differential colony hybridization with [32P] cDNA synthesized from enriched or low vitamin D-dependent calcium-binding protein mRNA preparations. Plasmid DNAs from the selected clones were each verified by both a solution hybrid-arrest assay and a filter hybrid-selection assay. Four recombinant clones showed identical endonuclease restriction maps and contained inserts ranging from 250 to 380 base pairs.
