Integrative Modeling in the Age of Machine Learning: A Summary of HADDOCK Strategies in CAPRI Rounds 47–55

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The HADDOCK team participated in CAPRI rounds 47–55 as server, manual predictor, and scorers. Throughout these CAPRI rounds, we used a plethora of computational strategies to predict the structure of protein complexes. Of the 10 targets comprising 24 interfaces, we achieved acceptable or better models for 3 targets in the human category and 1 ...

Biomolecular Interaction Prediction in the Pre‐ and Post‐AlphaFold Era: The 8th CAPRI Evaluation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We report on the 8th CAPRI Evaluation period, capturing the assessment of CAPRI Rounds 47 to 55 (excluding the CASP and COVID‐related Rounds), which have witnessed the transition to AI‐driven prediction tools such as AlphaFold and related alternatives. The prediction Rounds in this evaluation are characterized by a high level of difficulty due

Pairing of homologous chromosomes in C. elegans meiosis requires DEB-1 - an orthologue of mammalian vinculin

Nucleus, 2019
During meiosis, homologous chromosomes undergo a dramatic movement in order to correctly align. This is a critical meiotic event but the molecular properties of this ‘chromosomal dance’ still remainunclear.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice

Andrology, EarlyView.
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Surveillance of cohesin-supported chromosome structure controls meiotic progression

Nature Communications, 2020
Meiosis-specific cohesins and the synaptonemal complex are essential for meiotic chromosome structure and function. Here the authors show that continued surveillance of these chromosome structures controls meiotic progression by regulating CHK-2, a ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Synaptonemal complex components promote centromere pairing in pre-meiotic germ cells. [PDF]

PLoS Genetics, 2013
Mitosis and meiosis are two distinct cell division programs. During mitosis, sister chromatids separate, whereas during the first meiotic division, homologous chromosomes pair and then segregate from each other.

Sycp1 Is Not Required for Subtelomeric DNA Double-Strand Breaks but Is Required for Homologous Alignment in Zebrafish Spermatocytes

Frontiers in Cell and Developmental Biology, 2021
In meiotic prophase I, homologous chromosomes are bound together by the synaptonemal complex, in which two axial elements are connected by transverse filaments and central element proteins.

Variants in ZZS Complex‐Associated Genes TEX11 and M1AP Are Responsible for Male Infertility and Nonobstructive Azoospermia

Andrology, EarlyView.
ABSTRACT Background Nonobstructive azoospermia (NOA) is the most severe form of male infertility, with genetic factors contributing to approximately 30% of cases. However, only a small fraction of all NOA cases can be explained by the current genetic findings.
