What's a GeneRIF?

It has become apparent in the last decade that the stability or maturation of the PIKK family members depends on a molecular chaperone called the Tel2-Tti1-Tti2 (TTT) complex
Title: Branching the Tel2 pathway for exact fit on phosphatidylinositol 3-kinase-related kinases.
Our findings provide a model in which two different Tel2 pathways promote protein stabilization of Mec1 and Tel1 in budding yeast.
Title: Two separate pathways regulate protein stability of ATM/ATR-related protein kinases Mec1 and Tel1 in budding yeast.
present a structural and biochemical analysis of Hsp90-Tah1-Pih1, Hsp90-Spagh, and Pih1D1-Tel2 complexes that reveal a domain in Pih1D1 specific for binding CK2 phosphorylation sites
Title: Structural basis for phosphorylation-dependent recruitment of Tel2 to Hsp90 by Pih1.
Existence of a novel role for Tel2, namely in transcription, possibly in cooperation with Rvb2 and involving the existence of physical interactions with the Med15/Gal11 Mediator subunit.
Title: Genetic and physical interactions between Tel2 and the Med15 Mediator subunit in Saccharomyces cerevisiae.
these findings demonstrate separation of function explainable by differential binding of Tel2 to its PIKK substrates Tel1 or Tor1/Tor2 and thus a critical contribution of Tel2 to the interface that links various PIKKs to this chaperone complex.
Title: Saccharomyces cerevisiae Tel2 plays roles in TORC signaling and telomere maintenance that can be mutationally separated.
Tel2 can specifically and differentially regulate the function of individual PIKKs.
Title: Mec1 function in the DNA damage response does not require its interaction with Tel2.
Data show that Tel1 and Tel2 interact, and that even when Tel1 protein levels are high, this interaction is specifically required for Tel1 localization to a DNA break and its activation of downstream targets.
Title: Tel2 mediates activation and localization of ATM/Tel1 kinase to a double-strand break.
