CC -!- FUNCTION: Required for both chromosome condensation and segregation and
CC for X-chromosome dosage compensation depending on its binding partners
CC (PubMed:8939869, PubMed:8939870, PubMed:19119011, PubMed:2917714,
CC PubMed:19781752). Member of the condensin I complex, a complex required
CC for conversion of interphase chromatin into mitotic-like condense
CC chromosomes and for proper chromosome segregation in mitosis and
CC meiosis (PubMed:19119011, PubMed:19781752). As a member of the
CC condensin I complex, further controls the crossover number and
CC distribution in meiosis by restricting double strand break formation,
CC probably by influencing higher-order chromosome structure
CC (PubMed:19781752, PubMed:18198337). Plays a role in robust cytokinesis
CC upon presence of chromatin obstructions (PubMed:23684975). Also a
CC member of the condensin I-like dosage compensation complex that
CC associates specifically with hermaphrodite X chromosomes to reduce
CC their gene transcription during interphase, possibly through chromatin
CC reorganization (PubMed:19119011, PubMed:8939870, PubMed:2917714,
CC PubMed:19781752). As a member of the dosage compensation complex, also
CC binds to regulatory regions of the autosomal her-1 gene, required for
CC male development, possibly contributing to its repression in
CC hermaphrodites (PubMed:11937488). {ECO:0000269|PubMed:11937488,

CC ECO:0000269|PubMed:8939870}.
CC -!- SUBUNIT: Component of the condensin I complex, which contains the mix-
CC 1/SMC2 and smc-4/SMC4 heterodimer, and three non SMC subunits that
CC probably regulate the complex: dpy-26, capg-1 and dpy-28
CC (PubMed:19119011, PubMed:19781752). Within the complex, interacts with
CC dpy-28, mix-1, smc-4 and capg-1 (PubMed:15557118, PubMed:18198337,
CC PubMed:19781752, PubMed:19119011, PubMed:28301465). Component of the
CC dosage compensation complex, which consists of the condensin I-like
CC components mix-1/SMC2 and dpy-27/SMC4, and the three non SMC subunits
CC dpy-26, capg-1 and dpy-28 (PubMed:19119011, PubMed:19781752). Within
CC the complex, interacts with dpy-27, dpy-28, mix-1 and capg-1
CC (PubMed:8939870, PubMed:15557118, PubMed:18198337, PubMed:19781752,
CC PubMed:19119011, PubMed:9458050, PubMed:28301465). The interaction with
CC dpy-27 is required for dpy-27 protein stability (PubMed:8939870).
CC Interacts with smcl-1 (PubMed:28301465). {ECO:0000269|PubMed:15557118,

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:11937488,
CC ECO:0000269|PubMed:18198337, ECO:0000269|PubMed:8939869}. Chromosome
CC {ECO:0000269|PubMed:11937488, ECO:0000269|PubMed:18198337,
CC ECO:0000269|PubMed:8939869}. Note=During meiosis and mitosis, localizes
CC to condensed chromosomes (PubMed:8939869). In interphase cells,
CC diffusely distributed in nuclei of hermaphrodite embryos prior to the
CC onset of dosage compensation (PubMed:8939869). Localizes to the X
CC chromosome after the 40-cell stage when dosage compensation is
CC initiated in hermaphrodite (XX) but not in male (X0) embryos, where it
CC remains diffusely nuclear (PubMed:8939869, PubMed:18198337).
CC {ECO:0000269|PubMed:18198337, ECO:0000269|PubMed:8939869}.
CC -!- TISSUE SPECIFICITY: Expressed in embryos and in somatic and germline
CC tissues in L4 stage larvae (at protein level).
CC {ECO:0000269|PubMed:8939869}.
CC -!- DISRUPTION PHENOTYPE: Results in larval lethality in XX hermaphrodites;
CC survivors exhibit shorter and stouter body morphology and are egg-
CC laying defective (PubMed:2917714). Male animals are viable
CC (PubMed:2917714). Higher percentage of spontaneous males through X
CC chromosome non-disjunction (PubMed:2917714). Disrupts protein stability
CC of dpy-27 (PubMed:8939870). Disrupts localization of dpy-28 and of
CC capg-1 to the hermaphrodite X-chromosome (PubMed:18198337,
CC PubMed:19119011). RNAi-mediated knockdown results in chromosome
CC segregation defects in mitosis and meiosis (PubMed:19119011). In a sex-
CC 1 mutant background, leads to high embryonic lethality
CC (PubMed:19119011). {ECO:0000269|PubMed:18198337,
