Carica papaya bHLH Family

Description

Buck & Atchley. 2003: The basic helix-loop-helix (bHLH) family of proteins is a group of functionally diverse transcription factors found in both plants and animals. These proteins evolved early in eukaryotic cells before the split of animals and plants, but appear to function in lsquoplant-specificrsquo or lsquoanimal-specificrsquo processes. In animals bHLH proteins are involved in regulation of a wide variety of essential developmental processes. On the contrary, bHLH proteins have not been extensively studied in plants. Those that have been characterized function in anthocyanin biosynthesis, phytochrome signaling, globulin expression, fruit dehiscence, carpel and epidermal development.

Benchmark against A. thaliana

The Sensitivity and Positive Predictive Value (PPV) were assessed for this family. The data reported by Bailey et al. 2003 for A. thaliana were taken as gold standard.

The gold standard reported 154 members for this family, 122 of which are present in ArabTFDB, giving a PPV of 0.92. Thirty-two additional members not present in ArabTFDB might be false negatives, giving a Sensitivity of 0.80.

This family is also present in:
