DOI: 10.1016/j.ygeno.2020.10.006
Abstract: Beta satellite DNA (satDNA), also known as Sau3A sequences, are repetitive DNA sequences reported in human and primate genomes. It is previously thought that beta satDNAs originated in old world monkeys and bursted in great… read more here.

Visualization of the three-dimensional structure of the human centromere in mitotic chromosomes by super-resolution microscopy.
Sign Up to like & getrecommendations! Published in 2023 at "Molecular biology of the cell"
DOI: 10.1091/mbc.e22-08-0332
Abstract: The human centromere comprises large arrays of repetitive alpha-satellite DNA at the primary constriction of mitotic chromosomes. In addition, centromeres are epigenetically specified by the centromere-specific histone H3 variant CENP-A that supports kinetochore assembly to… read more here.

DOI: 10.1093/gbe/evx212
Abstract: Abstract In recent years, a growing body of evidence has recognized the tandem repeat sequences, and specifically satellite DNA, as a functional class of sequences in the genomic “dark matter.” Using an original, complementary, and… read more here.

DOI: 10.1093/molbev/msac162
Abstract: Abstract Centromeres are epigenetically specified by the histone H3 variant CENP-A and typically associated with highly repetitive satellite DNA. We previously discovered natural satellite-free neocentromeres in Equus caballus and Equus asinus. Here, through ChIP-seq with… read more here.

DOI: 10.1111/mec.16484
Abstract: Satellite DNA (satDNA) is a fast‐evolving portion of eukaryotic genomes. The homogeneous and repetitive nature of such satDNA causes problems during the assembly of genomes, and therefore it is still difficult to study it in… read more here.

DOI: 10.1126/sciadv.abp8085
Abstract: Mammalian genomes are a battleground for genetic conflict between repetitive elements and KRAB-zinc finger proteins (KZFPs). We asked whether KZFPs can regulate cell fate by using ZFP819, which targets a satellite DNA array, ZP3AR. ZP3AR… read more here.

DOI: 10.1139/gen-2022-0039
Abstract: Long terminal repeat (LTR) retroelements, including endogenous retroviruses, are one of the origins of satellite DNAs. However, the vast majority of satellite DNAs originating from LTR retroelements consist of parts of the element. In addition,… read more here.
