What's a GeneRIF?

Findings show how the structurally related Krr1 and Dim2 can control stepwise ribosome assembly during the 90S-to-pre-40S subunit transition.
Title: Interdependent action of KH domain proteins Krr1 and Dim2 drive the 40S platform assembly.
interaction between Dim2 and Nob1 is essential for optimal growth, and RNA binding experiments show that Dim2 increases Nob1 RNA affinity.
