Calcineurin responsive zinc-finger-1 binds to a unique promoter sequence to upregulate neuronal calcium sensor-1, whose interaction with MID-1 increases tolerance to calcium stress in Neurospora crassa.

abstract：:We show that Yersinia pestis and pesticin-sensitive isolates of Y. pseudotuberculosis possess a common 34 kbp DNA region that has all the hallmarks of a pathogenicity island and is inserted into different asparaginyl tRNA genes at different chromosomal locations in each species. This pathogenicity island (YP-HPI) is m...
