Abstract

H4K20 methylation is a broad chromatin modification that has been linked with diverse epigenetic functions. Several enzymes target H4K20 methylation, consistent with distinct mono-, di-, and trimethylation states controlling different biological outputs. To analyze the roles of H4K20 methylation states, we generated conditional null alleles for the two Suv4-20h histone methyltransferase (HMTase) genes in the mouse. Suv4-20h-double-null (dn) mice are perinatally lethal and have lost nearly all H4K20me3 and H4K20me2 states. The genome-wide transition to an H4K20me1 state results in increased sensitivity to damaging stress, since Suv4-20h-dn chromatin is less efficient for DNA double-strand break (DSB) repair and prone to chromosomal aberrations. Notably, Suv4-20h-dn B cells are defective in immunoglobulin class-switch recombination, and Suv4-20h-dn deficiency impairs the stem cell pool of lymphoid progenitors. Thus, conversion to an H4K20me1 state results in compromised chromatin that is insufficient to protect genome integrity and to process a DNA-rearranging differentiation program in the mouse.

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.
