Abstract |
The genome is highly organized hierarchically by the function
of structural maintenance of chromosomes (SMC) complex
proteins such as condensin and cohesin from bacteria
to humans. Although the roles of SMC complex proteins have
been well characterized, their specialized roles in nuclear processes
remain unclear. Condensin and cohesin have distinct
binding sites and mediate long-range and short-range genomic
associations, respectively, to form cell cycle-specific
genome organization. Condensin can be recruited to highly
expressed genes as well as dispersed repeat genetic elements,
such as Pol III-transcribed genes, LTR retrotransposon, and
rDNA repeat. In particular, mitotic transcription factors Ace2
and Ams2 recruit condensin to their target genes, forming
centromeric clustering during mitosis. Condensin is potentially
involved in various chromosomal processes such as the
mobility of chromosomes, chromosome territories, DNA reannealing,
and transcription factories. The current knowledge
of condensin in fission yeast summarized in this review can
help us understand how condensin mediates genome organization
and participates in chromosomal processes in other
organisms. |
