摘要
Two TGF-beta s, TGF-beta I and 2, have previously been isolated from the mouse. Here we report the isolation of a murine TGF-beta 3 cDNA. RNAs extracted from 15-day-old mouse embryos and several mouse cell lines were reverse-transcribed. These cDNA mixtures were used as substrates for polymerase chain-reaction amplifications, using oligonucleotides designed on the basis of known human and chicken TGF-beta 3 sequences, including the initiation and stop codons. Several overlapping cDNAs containing either the amino-terminal domain or the carboxy-terminal domain, as well as the complete 1.2-kb coding region of the mouse TGF-beta 3 cDNA were obtained. The mouse TGF-beta 3 coding region is 1230 nucleotides long and codes for a 410 amino acid polypeptide very similar to its human counterpart. This cDNA hybridizes to a unique 3.5-kb RNA and is differentially expressed in various mouse tissues and at different embryonic stages.
