Ostreococcus lucimarinus MYB-related Family


Martin & Paz-Ares. 1997: The cloning of the first transcription factor from plants, the C1 gene of maize, indicated that plants use transcription factors that are structurally related to those of animals in their control of gene expression, because C1 showed significant structural homology to the vertebrate cellular proto-oncogene c-MYB. Since 1987, the catalogue of MYB-related transcription factors has increased considerably in size due, primarily, to the ever-expanding number of MYB genes identified in higher plants (Arabidopsis thaliana is estimated to contain more than a hundred MYB genes). In vertebrates, the MYB-related proto-oncogenes comprise a small family with a central role in controlling cellular proliferation and commitment to development. However, while the functions of some plant MYB genes are relatively well understood they are, at present, quite distinct from their animal counterparts.

Benchmark against A. thaliana

The Sensitivity and Positive Predictive Value (PPV) were assessed for the families MYB and MYB-related jointly. The data reported by Yanhui et al. 2006 for A. thaliana were taken as gold standard.

The gold standard reported 198 members for this families, 184 of which are present in ArabTFDB, giving a PPV of 0.88. Fourteen additional members not present in ArabTFDB might be false negatives, giving a Sensitivity of 0.93.

This family is also present in:
