Structural basis of TnsC oligomerization and transposase recruitment in type I-B CRISPR-associated transposons.
CRISPR-associated transposon (CAST) systems employ CRISPR-Cas systems as RNA-directed targeting modules for site-specific transposon DNA insertion. Among them, type I CASTs rely on the coordinated action of the guide RNA-bound Cascade complex and the transposon proteins TniQ, TnsC, and TnsAB. The interaction between th...
