[Molecular Cloning of Smooth Muscle Calponin h1 in SHeep.].

It was found that the level of Calponin h1 (CaP h1) mRNA was significantly up-regulated by Estrogen in the myometrium of sheep towards the end pregnancy. Although the CaP h1 has been widely used as a reference gene to observe the changes of expression level of other genes, the full-length gene in sheep has not been obtained. With the oligo nucleotide primers according to human, mouse and pig CaP h1 mRNA, the full-length cDNA of CaP h1 was cloned by 5'- and 3'-RACE (Genbank accession number = AY327118).
