An Annotated Catalog of Inverted Repeats of Caenorhabditis elegans Chromosomes III and X, with Observations Concerning Odd/Even Biases and Conserved Motifs

Inverted repeats in promoter region of a gene for heat shock protein hsp104. Note that this locus is rich with many additional inverted repeats of the type highlighted except that they fall below the limits of resolution of the search that stipulated no more than 10% mismatches on the stem. Motifs in this region include numerous GAA boxes and estrogen response elements (ERE) both identified in other heat shock promoters as well as GTGAC and TAGGTCA motifs. Two examples of GAA and ERE are boxed in this figure. The locus resembles the satellite-like configuration reported in other heat shock promoters.
