Chapter 4 β‐Globin Regulation and Long‐Range Interactions

Abstract

Transcriptional activation in higher eukaryotes frequently involves the long-range action of a number of regulatory DNA elements. One of the main questions in transcriptional regulation is how cis-regulatory elements communicate with the promoter of a gene over large distances. There has been a lively debate in recent years whether this communication takes place via a noncontact mechanism (linking, tracking) or via a contact mechanism (looping). The demonstration that the major regulatory element of the beta-globin locus, the locus control region (LCR), is in close proximity to the active beta-globin genes validates the contact model for long-range activation. Here, we will review the beta-globin locus as a model system to study long-range activation, briefly describe the different models for long-range activation, and summarize the recent findings that the LCR of the beta-globin locus is in close proximity to the active promoters. Although it is now firmly established that looping takes place within the beta-globin locus (and other loci), it is not clear how these long-range contacts are established and what the precise role is of the LCR. We will argue that the main action of the LCR takes place at the promoter and open reading frame of the gene itself and we will discuss key rate-limiting steps in transcriptional activation and the possible mechanisms by which they are influenced by the LCR.

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.
