Expression and regulation
- Regulation:
- Regulatory mechanism:
- Additional information:
- Northern blotting during during phosphate limitation showed an intense 0.25 kb skfA-specific transcript, and a weaker 6.5 kb skfA-skfB-skfC-skfE-skfF-skfG-skfH transcript.
- The skfA transcript is stabilized by a stem-loop structure in the skfA-skfB intergenic region. PubMed
- The mRNA is very stable (half-life > 15 min) PubMed
