Protein Protein Interfaces
Speaker: Johannes Rudolph, Department of Biochemistry

Protein-protein interactions form the basis for most cellular 
processes,
including events intimately linked to human diseases.  Despite their
importance, our understanding of the molecular details of 
protein-protein
interactions remains poor, lagging far behind that of protein folding 
and
structure.  Descriptors and visual tools that describe protein 
interfaces
are needed to discover the universal rules expected to govern the
specificity and efficiency of protein-protein association.  Recently, 
we
have used tools from computational geometry to define a protein 
interface
surface.  We can define a hierarchy of structures on this interface 
surface.
Primary structure describes adjacencies, either on one side of the 
interface
or across the interface.  Secondary structure describes small recurring
geometric motifs.  Tertiary structure describes the landscape of these
motifs.  Here we describe the visualization of these primary and 
secondary
structures of protein interfaces.
