What's a GeneRIF?

A fragment of Ssp2 that is sufficient to activate Smk1 contains two segments that resemble RNA recognition motifs (RRMs). Mutations in either of these motifs eliminated Ssp2's ability to activate Smk1. In contrast, deletions and insertions within the segment linking the RRM-like motifs only partially reduced the activity of Ssp2.
Title: RNA Recognition-like Motifs Activate a Mitogen-Activated Protein Kinase.
The T residue in Smk1's activation motif is phosphorylated by the cyclin-dependent kinase (CDK)-activating kinase, Cak1.
Title: Activation of the Smk1 mitogen-activated protein kinase by developmentally regulated autophosphorylation.
Ime2 is a key activator of Smk1 signaling.
Title: The Ras/cAMP pathway and the CDK-like kinase Ime2 regulate the MAPK Smk1 and spore morphogenesis in Saccharomyces cerevisiae.
negative regulation of GSC2 by SMK1 is important for spore wall deposition
Title: The Smk1p MAP kinase negatively regulates Gsc2p, a 1,3-beta-glucan synthase, during spore wall morphogenesis in Saccharomyces cerevisiae.

EC 2.7.11.24

Middle sporulation-specific mitogen-activated protein kinase (MAPK); required for prospore membrane development and the production of outer spore wall layers; negatively regulates activity of the glucan synthase subunit Gsc2p; activated by Cak1p-mediated phosphorylation of threonine (T207) in the activation loop during meiosis I followed by Ssp2p-promoted autophosphorylation of tyrosine (T209) during meiosis II
