Putting a finger on the switch
Open accessAbstract
The transition from fetal to adult beta-like globin expression is a key step in the maturation of the red blood cell lineage. Two new studies show that the KLF1 zinc finger protein uses direct and indirect means to regulate the final switch from fetal to adult globin expression and that monoallelic loss of KLF1 expression leads to persistence of fetal hemoglobin.

KLF1 binds to the promoter of ZBTB7A increasing its expression, and KLF1 also activates the expression of BCL11A.
“Kr üppel-like factor 1 (KLF1) binds to the promoter of ZBTB7A increasing its expression; KLF1 also activates the expression of BCL11A.28,29”
From Fetal hemoglobin in sickle cell anemia (2020) · cites this paper as [29]
The Common ties section reports that KLF1 binds the BCL11A gene and that BCL11A levels rise with KLF1 levels, supporting the BCL11A part of the claim. Our copy does not mention ZBTB7A or say that KLF1 binds its promoter or increases its expression. (LLM, conf=0.89)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
