Polymorphism of the KAP1
.3 and K33 genes in Merino sheep.
To protect host genome from the deleterious effect in somatic tissues, retrotransposons are recognized by factors like KRAB-ZFPs and KAP1
(TRIM28) and completely silenced through DNA methylation, histone methylation/acetylation, and posttranscriptional regulation , except in the brains where they provide genetic variations among neurons .
, also known as TRIM28 (tripartite motif protein 28), acts as a scaffold for a multimolecular complex that silences transcription through the formation of heterochromatin [24, 25].
To monitor ATM activation, we examined the phosphorylation status of three well-characterized ATM targets: ATM autophosphorylation at Ser1981, CHK2 at Thr68, and transcription/chromatin regulator KAP1 at Ser824 (Shiloh and Ziv 2013).
Similarly to parental H460 cells with restored Asc, the shRNA-expressing lines showed no increases in phosphorylation of the ATM targets CHK2 and KAP1 after Cr(VI) exposure (Figure 3A).
(136) It functions together with its cofactor, KRAB-associated protein 1 (KAP1
, also called TRIM28).
In a paper published this week in Science, Isabelle Barde of the EPFL's School of Life Sciences and Frontiers in Genetic Program, and colleagues, describe experiments which show that KRAB-containing zinc finger proteins, working in concert with a cofactor called KAP1, modulate mitophagy in subtle and sophisticated ways.
The researchers found that mice genetically modified to lack KAP1 quickly became anemic because they were unable to make red blood cells.
