Exploring the expression and preliminary function of chicken Gimap5 gene.
Ontology highlight
ABSTRACT: GTPase immune-associated protein 5 (Gimap5) plays a key role in maintaining T cell homeostasis, immunological tolerance and inflammatory processes. However, there are no reports on the chicken Gimap5 gene. In this study, the Gimap5 gene was first cloned from chicken and characterized its tissue expression characteristics in different developmental stages. The transcriptional activities of the Gimap5 gene in immune response were identified. The results showed that full-length cDNA sequence of Gimap5 contained 771 bp and encoded a 256-amino acid protein. The Gimap5 gene was transcribed in various tissues and different development stages. The transcriptional activities of Gimap5 gene in the most tissues increased with the development of chicken, but significantly up to peak in liver and large intestine of 10-month-old chicken. The Gimap5 gene exhibited differential transcriptional activities in immune-related tissues in immune responses, with down-regulated in liver (P < 0.01), spleen (P < 0.05) and bursa of Fabricius (P < 0.05), and up-regulated in thymus (P < 0.01). The results show that Gimap5 may be a multifunctional gene involved in tissue function, development and immune response in chicken. These data can provide the foundation for further study of Gimap5.
