Phosphorylation regulates association of the transcription factor Pho4 with its import receptor Pse1/Kap121

Article Abstract:

The requirements for import of the transcription factor Pho4 to the cell nucleus in growing yeast in phosphate-rich media have been investigated. Pho4 enters the nuclei via a nonclassical pathway using an importin beta family member, Pse1/Kap121. Phosphorylation regulates association of Pho4 with this import receptor.

From insect eye to vertebrate muscle: redeployment of a regulatory network

Article Abstract:

This article discusses conservation of the embryogenesis signaling systems across species, from invertebrates to vertebrates. Data show that same set of transcriptional regulators involved in invertebrate eye formation are deployed in the vertebrate embryogenesis.
