High-resolution mapping of chromatin packaging in mouse embryonic stem cells and sperm

Mammalian embryonic stem (ES) cells and sperm exhibit unusual chromatin packaging that plays important roles in cellular function. Here, we extend a recently developed technique, based on deep paired-end sequencing of lightly digested chromatin, to assess footprints of nucleosomes and other DNA-binding proteins genome-wide in murine ES cells and sperm. In ES cells, we recover well-characterized features of chromatin such as promoter nucleosome depletion, and further identify widespread footprint...

Provenance — who produced it, who reused it

Linked to 4 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained

No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.

measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
