Co-transcriptional assembly of the small subunit processome. Schematic representation of early events of small subunit assembly in the nucleolus and subsequent maturation resulting in the mature cytoplasmic SSU. A section of the rDNA locus is shown with 5′ ETS and ITS1 colored in yellow and 18S colored in red (5′ domain), green (central domain) and slate (3′ domain). Factors visualized in the assembled SSU processome [30] are shown as schematic outline while transient components are listed and colored according to the rRNA domain they are associated with [19,20]. The SSU processome and its major components are shown in detail below.
