Summary
The synaptonemal complex (SC) is crucial for chromosome pairing and genetic exchange during meiosis. Its dysfunction can cause infertility and is linked to cancer development.
Area of Science:
- Cell Biology
- Genetics
- Reproductive Biology
Background:
- The synaptonemal complex (SC) is a meiosis-specific structure essential for homologous chromosome pairing and recombination.
- SC assembly facilitates double-strand break formation, repair, and crossover maturation, critical for accurate genome segregation.
- Dysfunction in SC proteins or meiotic recombination can lead to meiotic arrest and human infertility.
Purpose of the Study:
- To review the significance of the SC and associated proteins in human fertility.
- To explore how genetic variants in these proteins impact meiosis, infertility, and cancer development.
Main Methods:
- Literature review of studies on synaptonemal complex function and associated proteins.
- Analysis of genetic variants affecting meiotic processes.
- Examination of links between meiotic dysfunction and cancer.
Main Results:
- SC proteins are vital for successful meiosis and fertility.
- Defects in SC assembly or function lead to infertility.
- Aberrant expression and genetic variants in SC-associated genes are implicated in cancer.
Conclusions:
- The synaptonemal complex and its associated proteins are critical for male and female fertility.
- Understanding these proteins and their genetic variations offers insights into infertility and potential cancer therapies.

3.3K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

4.6K
Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.

Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of...

3.5K
Condensins are large protein complexes that use ATP to fuel the assembly of chromosomes during mitosis. They transform the tangled, shapeless mass of post-interphase DNA into individualized chromosomes by compacting, organizing, and segregating chromosomal DNA.
The plant and animal cells contain two types of condensin complexes—condensin I and condensin II. Both complexes have five subunits: two SMC (Structural Maintenance of Chromosomes) subunits, a kleisin subunit, and two HEAT-repeat...

10.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

01:49Meiosis I
193.8K
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by...

00:50Anaphase Promoting Complex
2.9K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...
