The associated variant, rs189296436, is a missense variant inSYCE2(NM_001105578.1:c.265C>T p.His89Tyr) with a minor allele frequency (MAF) of 0.18–1.27% in the study populations (Supplementary Table2). SYCE2 is part of the synaptonemal complex, a protein structure that mediates alignment,...
1.9.5 Four Levels of Protein Structure Proteins have four levels of structure: primary, secondary, tertiary, and quaternary. Primary structure refers to the amino acid sequence of a protein. Secondary structure refers to the conformation of the polypeptide backbone. Examples of secondary structures ar...
Protein structures are not fully flexible; there are physical constraints on polypeptide conformation [7–11]. It is believed that the 3D structure can be reduced to a simpler form while maintaining the intrinsic structural information [12–24]. With the reduced data, a similarity search can beco...

Here, we determined the structure of human DNAM-1 in complex with one of its cognate ligands, Necl-5. DNAM-1 bound Necl-5 in a 1:1 stoichiometry via a docking mode that enabled the interaction between lock and key motifs within their respective D1 domains. The unconventional “collapsed...
Protein function, regulation, and interactions can be learned from their structure [1,2], which motivates development of novel methods for the prediction of the protein structure. These predictions concern various levels and aspects of the protein structure including the tertiary structure [3,4], so...
