What's a GeneRIF?

The multiple nucleotide-divalent cation binding modes of Saccharomyces cerevisiae CK2alpha indicate a possible co-substrate hydrolysis product (ADP/GDP) release pathway.
Title: The multiple nucleotide-divalent cation binding modes of Saccharomyces cerevisiae CK2α indicate a possible co-substrate hydrolysis product (ADP/GDP) release pathway.
CK2 activity is directly correlated to growth rate and not to the carbon source.
Title: CK2 activity is modulated by growth rate in Saccharomyces cerevisiae.

These data may help to elucidate the role of yeast protein kinase CK2beta/beta' subunits in the regulation of holoenzyme assembly and phosphotransferase activity.
Title: Yeast holoenzyme of protein kinase CK2 requires both beta and beta' regulatory subunits for its activity.
Yeast transcription elongation factor Elf1 has been identified as a new substrate for protein kinase CK2 and coimmunoprecipitation shows that Elf1 interacts with catalytic (alpha and alpha') as well as regulatory (beta and beta') subunits of CK2.
Title: Yeast elf1 factor is phosphorylated and interacts with protein kinase CK2.
