Data suggest that osmotic stress induces hyperphosphorylation of mitotic inducer cdr1 for several hours and cells delay division during same time period; this stress-induced hyperphosphorylation requires both cdr1 autophosphorylation and stress-activated protein kinase sty1. (cdr1 = serine/threonine protein kinase cdr1/nim1; sty1 = MAP kinase sty1)

Data suggest that S. pombe 972 expressing a nonphosphorylatable Atf1 variant is more sensitive to oxidative stress because of impaired transcription of subset of stress genes whose expression is controlled by Pap1; in S. pombe 972 expressing phospho-mimicking Atf1 mutant, presence of Sty1 is completely dispensable. (Atf1 = transcription factor Atf1; Sty1 = MAP kinase Sty1; Pap1 = transcription factor Pap1)

The fission yeast stress-activated protein kinase Sty1, a homolog of mammalian p38 MAP kinase, regulates localization of the Cdc42 polarity module.

Threonine-monophosphorylated Sty1 displays a limited biological activity particularly at the transcriptional level.

Data suggests that Sty1 activation promotes Pyp2 phosphorylation to increase the stability of the phosphatase. This MAPK-dependent Pyp2 stabilisation allows cells to attenuate MAPK signalling and resume cell division, once stresses have been dealt with.
