Irf8 | Interferon regulatory factor 8; Plays a role as a transcriptional activator or repressor (By similarity). Specifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes (the interferon consensus sequence (ICS)). Plays a negative regulatory role in cells of the immune system. Involved in CD8(+) dendritic cell differentiation by forming a complex with the BATF-JUNB heterodimer in immune cells, leading to recognition of AICE sequence (5'-TGAnTCA/GAAA-3'), an immune-specific regulatory element, followed by cooperative binding of BATF and IRF8 and act [...] (424 aa) | ||||
Pde8a | High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8A; Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in maintaining basal levels of the cyclic nucleotide and/or in the cAMP regulation of germ cell development. Binding to RAF1 reduces RAF1 'Ser- 259' inhibitory-phosphorylation and stimulates RAF1-dependent EGF- activated ERK-signaling. Protects against cell death induced by hydrogen peroxide and staurosporine. (823 aa) |
