Function of heterochromatin protein 1 during DNA repair

Protoplasma, 2017
This review focuses on the function of heterochromatin protein HP1 in response to DNA damage. We specifically outline the regulatory mechanisms in which HP1 and its interacting partners are involved. HP1 protein subtypes (HP1α, HP1β, and HP1γ) are the main components of constitutive heterochromatin, and HP1α and HP1β in particular are responsible for ...

Analysis of the heterochromatin protein 1 (HP1) interactome in Drosophila.

Journal of Proteomics, 2014
Heterochromatin protein 1 (HP1) was first described in Drosophila melanogaster as a heterochromatin associated protein required for epigenetic gene silencing. Most eukaryotes have at least three HP1 homologs that play differential roles in heterochromatin and euchromatin.

Heterochromatin protein 1 expression is reduced in human thyroid malignancy [PDF]

open access: yesLaboratory Investigation, 2014
Owing to the loss of heterochromatin integrity that occurs during thyroid tumorigenesis, the expression of Heterochromatin Protein 1 isoforms HP1α and HP1β was assessed by immunohistochemistry in 189 thyroid tumors and non-neoplastic tissues. Expression of HP1β was significantly decreased in all thyroid lesions, except in follicular adenomas, when ...

Heterochromatin protein 1 binds transgene arrays

Chromosoma, 1998
Heterochromatin protein 1 (HP1) of Drosophila and its homologs in vertebrates are key components of constitutive heterochromatin. Here we provide cytological evidence for the presence of heterochromatin within a euchromatic chromosome arm by immunolocalization of HP1 to the site of a silenced transgene repeat array.
