condensin

[kən′den·sən]
(cell and molecular biology)
The class of proteins that form condensin complexes, which drive the coiling of interphase chromosomes, leading to their condensation prior to mitosis.

Increased number of chromatin bridges in anaphase has been described for condensin II knockout cells as well as condensins I and II depleted cells [39, 40].
In vertebrates, condensins I and II are both composed of the SMC2/4 heterodimer together with distinct additional non-SMC subunits, CAP-G/G2, CAP-D2/D3, and CAPH/H2 [18].

SMC4 which forms a complex with SMC2 in condensin was also pulled down by GST-Nesprin-2-SMC.
As condensin exists in two complexes, condensin I and condensin II [18], we used CAP-H (kleisin [gamma], non-SMC condensin I complex subunit H) and CAP-H2 (kleisin [beta], non-SMC condensin II complex subunit H2) antibodies to probe the GST-Nesprin-2-SMC pulldown and identified CAP-H and CAP-H2 in the precipitate (Figure 3(c)).
Nesprin-2 Knockdown Does Not Affect Condensin Distribution.
In summary, we report a novel interaction partner of Nesprin-2 giant and show that the Nesprin-2 condensin interaction has an impact on mitotic chromosomes.
Alternatively, the interaction between condensin and Nesprin-2 is an indirect one.
Condensins, proteins which play a major role in chromosome condensation and DSB repair during prophase I, are also known to play a role [66].

As the chromosomes condense, REC8 is cleaved on the chromosome arms and the cohesin complex is replaced by the condensin complex.
I will use innovative methods for acute protein inactivation, developed during my postdoctoral studies, to evaluate the role of two key protein complexes involved in mitotic chromosome architecture - Condensins and Cohesins.
