| Abstract |
In Caenorhabditis elegans embryogenesis, phosphorylation events are critical to chromosomal changes. To investigate the dephosphorylation of chromosome behavior, we cloned and characterized the cDNA that encodes C. elegans protein phosphatase type 1 (CeGLC-7 beta), which is composed of 333 amino acids. CeGLC-7 beta possesses a highly conserved amino acid sequence with mammalian and Drosophila protein phosphatase 1. Here, we report on the contribution of CeGLC-7 beta to the dephosphorylation of histone H3 at anaphase. At the embryonic stage, CeGLC-7 beta is associated with the nuclear membrane and chromosomes. The deletion of the Ceglc-7 beta gene and a microinjection of double-stranded RNA produce a disorganized embryogenesis. The Ceglc-7 beta gene mutation causes an abnormal accumulation of phosphorylated histone H3 and delays the mitotic process after anaphase. We propose that CeGLC-7 beta is involved in chromosome dynamics including histone H3 dephosphorylation. |
