However, there is sparse information about their structure, tissue expression, in birds, where their biological functions remain unknown. In this study,we cloned and characterized two SOCS1 genes(named c SOCS1 a and c SOCS1b) from chickens. SOCS1 a is predicted to encode a 207-amino acid protein, which shares high amino acid sequence identity(64%–67%) with human and mouse SOCS1. Besides SOCS1 a, a novel SOCS1 b gene was also identified in chickens and other non-mammalian vertebrates including Xenopus tropicalis.Chicken SOCS1 b is predicted to encode a 212-amino acid protein, which shares only 30%–32% amino acid sequence identity with human SOCS1 and c SOCS1 a. RT-PCR assay revealed that both c SOCS1 a and c SOCS1 b are widely expressed in all chicken tissues. Using a luciferase reporter assay system, we further demonstrated that transient expression of c SOCS1 a and c SOCS1 b can significantly inhibit chicken growth hormone(GH)- or prolactin(PRL)-induced luciferase activities of Hep G2 cells expressing c GH receptor(or c PRL receptor), indicating that SOCS1 a and SOCS1 b proteins can negatively regulate GH/PRL signaling. Taken together, these data suggest that both c SOCS1 a and c SOCS1 b may function as negative regulators of cytokine/hormone actions, such as modulation of GH/PRL actions in chickens.展开更多
