High impact information on APS4
- A putative TATA box was identified in the promoter of the APS3 and APS4 genes, but no regions of sequence similarity were found among the other promoters [1].
- Combined analysis of an APS4 cDNA and genomic clone revealed that the deduced protein is 469 amino acids and is most homologous to the A. thaliana APS1 subclass [1].
- The APS4 protein exhibits a plastid targeting peptide at its amino terminus that, when fused to green fluorescent protein, was able to target the reporter to chloroplasts [1].
- APS4 mRNA was detected at a similar steady-state level in roots and leaves, and its expression was not induced by sulfur starvation or by O-acetylserine treatment [1].
