SYP-4 phosphoproteomics characterization


ABSTRACT: The deletion of the last 114 amino acids of SYP-4 introduced severe defects in crossover regulation during meiosis I in C. elegans. Many processes during meiosis are regulated by post-translational modifications. Therefore, we aimed at identifying putative phosphorylation sites within the last 114 amino acids of SYP-4 by mass spectrometry to later test their functionality.

Crossovers are regulated by a conserved and disordered synaptonemal complex domain.

During meiosis, the number and distribution of crossovers (COs) must be precisely regulated through CO assurance and interference to prevent chromosome missegregation and genomic instability in the progeny. Here we show that this regulation of COs depends on a disordered and conserved domain within the synaptonemal complex (SC). This domain is located at the C-terminus of the central element protein SYP-4 in Caenorhabditis elegans. While not necessary for synapsis, the C-terminus of SYP-4 is cru  ...[more]
