Microcephalin Is a DNA Damage Response Protein Involved in Regulation of CHK1 and BRCA1

Abstract

Microcephalin (MCPH1) is the first gene identified among at least six loci that contribute to the autosomal recessive disease, primary microcephaly. MCPH1, like NFBD1/MDC1, 53BP1, and BRCA1, encodes a protein with twin carboxyl-terminal BRCT domains (PTCB). Here, we report that Mcph1 forms ionizing radiation-induced foci. Down-regulation of Mcph1, like other PTCBs, by siRNA, impairs ionizing radiation-induced intra-S-phase and G(2)/M checkpoints. Inhibition of the expression of Mcph1 decreases both protein and transcript levels of endogenous Brca1 but not exogenous Brca1. Mcph1 inhibition also decreases both endogenous and heterologous Chk1 transcripts and protein. We conclude that Mcph1 is involved in DNA damage-induced cellular responses, and we propose that regulation of Brca1 and/or Chk1 by Mcph1 may contribute to these cellular responses.

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.
