'''CSL (Lag-1) bound to DNA with Lin-12 RAM peptide, C2221'''
== Function ==
 
[https://www.uniprot.org/uniprot/LIN12_CAEEL LIN12_CAEEL] Involved in several cell fate decisions that require cell-cell interactions. It is possible that lin-12 encodes a membrane-bound receptor for a signal that enables expression of the ventral uterine precursor cell fate. Activity in cell fate decisions and tumorigenesis is negatively regulated by sel-10.<ref>PMID:3419531</ref> <ref>PMID:3000611</ref>

==Overview==
[[Image:Consurf_key_small.gif|200px|right]]
The Notch pathway is a conserved cell-to-cell signaling mechanism, in which extracellular signals are transduced into transcriptional outputs through the nuclear effector CSL. CSL is converted from a repressor to an activator through the formation of the CSL-NotchIC-Mastermind ternary complex. The RAM domain of NotchIC avidly interacts with CSL; however, its role in assembly of the CSL-NotchIC-Mastermind ternary complex is not understood. Here we provide a comprehensive thermodynamic, structural, and biochemical analysis of the RAM-CSL interaction for components from both mouse and worm. Our binding data shows that RAM and CSL form a high affinity complex in the presence or absence of DNA. Our structural studies reveal a striking distal conformational change in CSL upon RAM binding, which creates a docking site for Mastermind to bind to the complex. Finally, we show that the addition of a RAM peptide in trans facilitates formation of the CSL-NotchIC-Mastermind ternary complex in vitro.
