Abstract: In order to elucidate the characteristics and expression profile of Calm1 in ovarian hierarchical follicles and tissues of Sichuan white goose,the Calm1 coding region sequence of the goose was clone,and it's structure and function was characterized.The relative abundance of Calm1 mRNA in ovarian follicles and various tissues of Sichuan white goose were assessed by quantitative Real-time PCR.The results showed that the Calm1 coding sequence was 450 bp with encoding 149 amino acid residues.The sequence of the goose Calm1 amino acids shared a 99% similarity compared to Gallus gallus.The level of Calm1 gene expression in cerebrum was significantly higher than others (P<0.05). Calm1 transcripts were detectable in all of the experimental follicles.The level of Calm1 gene expression in F2 was 1.76-fold compared with small white follicles,and was significantly higher than F5,F4,F3 and F1 level follicle (P<0.05).The level of Calm1 in postovulatory follicle 1 was significantly higher than POF2,POF3 and POF4 (P<0.05).The Calm1 expression level in ovarian tissue was 1.75-fold compared with small white follicles (P<0.05).Calm1 is a highly conserved ubiquitous protein.Calm1 may participate in regulating the animal reproduction by affecting the growth of follicular cell proliferation and synthesis of steroid hormones.
