A	PF17911	Ski2 N-terminal region (Ski2_N)	Ski2 N-terminal region	This region is the N-terminal extended region found in the Ski2 protein. The Ski complex is a conserved multiprotein assembly required for the cytoplasmic functions of the exosome, including RNA turnover, surveillance, and interference [1]. Ski2, Ski ...	This region is the N-terminal extended region found in the Ski2 protein. The Ski complex is a conserved multiprotein assembly required for the cytoplasmic functions of the exosome, including RNA turnover, surveillance, and interference [1]. Ski2, Ski3, and Ski8 assemble in a tetramer with 1:1:2 stoichiometry.	Domain
