OsCIPK08 is a member of CIPK genes (CIPKs,calcineurin B-like protein interacting protein kinases) in rice[1].

Annotated Information


Almost all OsCIPK proteins contain the complete protein kinase domain (except OsCIPK21) and the NAF domain (except OsCIPK8). OsCIPK08 has lost the region containing the FISL/NAF motif, but it contains the full N-terminal catalytic domain (sharing sequence homology with SNF)[1].

GO assignment(s): GO:0004672,GO:0004674, GO:0006468, GO:0005524, GO:0007165


OsCIPK08 was induced by salinity stress[1], the expression of OsCIPK08 was relatively high in the shoot[2].


OsCIPK08 belongs to subgroup I of OsCIPK family[2].

Knowledge Extension

Figure 1. Functional gene network analysis of OsCIPK family members.(from reference [2]).
  • From real-time RT-PCR analyses, Giong et al. identified 16 OsCIPK genes showing a significant up- or down-regulation in response to drought stress. Using the probable functional gene network tool, RiceNet, Giong et al. generated a hypothetical functional gene network based on 15 out of 16 OsCIPK proteins (Fig. 1)[2].
  • More than 200 interactions mediated by these OsCIPK proteins. This network was further refined by integrating fold change data showing at least 1 log2-fold up-regulation (red colored nodes in Fig. 1) or less than -1 log2-fold down-regulation (green colored nodes in Fig. 1) under drought stress to all the elements in this network[2].
  • Integrated subcellular localization data further enhances the feasibility of functional modules consisting of co-expressed functional groups such as CIPK and PPC and other components in the network(Fig. 1)[2].
  • The calcineurin B-like protein–CBL-interacting protein kinase (CBL–CIPK) signaling pathway in plants is a Ca2+-related pathway that responds strongly to both abiotic and biotic environmental stimuli[3]. The CBL-CIPK system shows variety, specificity, and complexity in response to different stresses, and the CBL–CIPK signaling pathway is regulated by complex mechanisms in plant cells[3].
