Synaptonemal complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.

Summary
Liquid crystalline structure that assembles between homologous chromosomes during meiotic prophase. Required for stabilising chromosome pairing and alignment, and for crossover events and chiasmata formation between homologous chromosome pairs. Mediates the lengthwise alignment of homologous chromsomes within 100 nm of each other witht hread-like axial or lateral elements are paired together by transverse filaments formed by oligomerized ZIP1 proteins. The axial element contains the axis proteins RED1 and HOP1 which appear to require the activity of the meiotic cohesin complex (CPX-1408) for correct assembly. ZIP1 dimers are organized near their N-termini by a complex of proteins including ECM11 and SUMOylated ECM11. ECM11 SUMOylation promotes ZIP1 assembly whilst ZIP1 promotes ECM11 SUMOylation in a positive feedback loop leading to further assembly of ZIP1, loading of ECM11/GMC2 and SUMOylation of ECM11 until the Synaptonemal complex is fully established.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.

DNA metabolic process, DNA recombination, cellular nitrogen compound metabolic process, chromosome organization, chromosome, nuclear chromosome, organelle

Biological Process

Manually curated GO annotations reflect our best understanding of the basic biological process for this protein complex. Manually curated annotations are assigned by curators based on published papers when available, or by curatorial statements if necessary. Curators periodically review all manually curated GO annotations for accuracy and completeness.

Shared Annotations

This diagram displays Gene Ontology terms (green) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). Note: No diagram is shown ("No shared annotations") if there are less than 2 shared GO annotations between this complex and any other complexes.
