Osipov Y, Posukh O, Kalashnikova D, Antoshina P, Laktionov P, Skrypnik P, et al.
Chromosoma
. 2023 Sep;
132(4):317-328.
PMID: 37700063
Using a new method for bulk preparation of early stage embryos, we have investigated the role played by putative Planococcus citri H3K9 and H4K20 histone methyl transferases (HMTases) in regulating...

Epigenetics Chromatin
. 2018 Apr;
11(1):14.
PMID: 29609617
Background: During Drosophila spermatogenesis, testis-specific meiotic arrest complex (tMAC) and testis-specific TBP-associated factors (tTAF) contribute to activation of hundreds of genes required for meiosis and spermiogenesis. Intriguingly, tMAC is paralogous...

Epigenetics Chromatin
. 2017 Dec;
10(1):56.
PMID: 29191233
Background: In eukaryotes, heterochromatin replicates late in S phase of the cell cycle and contains specific covalent modifications of histones. SuUR mutation found in Drosophila makes heterochromatin replicate earlier than...

Chromosoma
. 2017 Oct;
127(1):85-102.
PMID: 28975408
Histone modifications represent one of the key factors contributing to proper genome regulation. One of histone modifications involved in gene silencing is methylation of H3K9 residue. Present in the chromosomes...

Genes Dev
. 2017 Apr;
31(6):603-616.
PMID: 28404631
Eukaryotic DNA replicates asynchronously, with discrete genomic loci replicating during different stages of S phase. larval tissues undergo endoreplication without cell division, and the latest replicating regions occasionally fail to...

Posukh O, Maksimov D, Skvortsova K, Koryakov D, Belyakin S
Nucleus
. 2015 Jul;
6(4):249-53.
PMID: 26211696
Replication of chromosomes is central to heredity. To become available for replication machinery, DNA invariably needs to dissociate from chromatin proteins. Yet, chromatin landscape must be promptly re-established during or...

Kolesnikova T, Posukh O, Andreyeva E, Bebyakina D, Ivankin A, Zhimulev I
Chromosoma
. 2012 Nov;
122(1-2):55-66.
PMID: 23149855
Drosophila SUUR (Suppressor of UnderReplication) protein was shown to regulate the DNA replication elongation process in endocycling cells. This protein is also known to be the component of silent chromatin...

Genetics
. 2009 Jul;
183(1):119-29.
PMID: 19596903
Different genomic regions replicate at a distinct time during S-phase. The SuUR mutation alters replication timing and the polytenization level of intercalary and pericentric heterochromatin in Drosophila melanogaster salivary gland...
