Ski2, Ski3, and Ski8 assemble in a tetramer with 1:1:2 stoichiometry; 370 kDa core complex shows that Ski3 forms an array of 33 tetratricopeptide repeat motifs organized in N-terminal and C-terminal arms. The C-terminal arm of Ski3 and the two Ski8 subunits position the helicase core of Ski2 centrally within the complex, enhancing RNA binding.
Title: The yeast ski complex: crystal structure and RNA channeling to the exosome complex.

Ski3p serves as a scaffold protein with its C terminus interacting with Ski8p.
Title: Domain interactions within the Ski2/3/8 complex and between the Ski complex and Ski7p.

Mapping sequence conservation and hydrophobicities of amino acids on the molecular surface of Ski8p reveals a prominent site on the top surface of the beta propeller, which is most likely involved in mediating interactions of Ski8p with Ski3p and Spo11p
Title: Crystal structure of Ski8p, a WD-repeat protein with dual roles in mRNA metabolism and meiotic recombination.

Ski8p has seven WD repeats, demonstrating that many WD repeats have not yet been identified in sequences and also raises the possibility that the seven-bladed propeller may be the predominant fold for this family of proteins
