Using the human melanocortin-2 receptor as a model for analyzing hormone/receptor interactions between a mammalian MC2 receptor and ACTH(1-24)

Abstract

When considering the interactions between the melanocortin peptides (i.e., ACTH, α-MSH, β-MSH, γ-MSH) and the melanocortin receptors (i.e., MC1R, MC2R, MC3R, MC4R, MC5R), it appears that the structure/function relationship between ACTH and MC2R is the most complicated. Human ACTH(1-24) and the human melanocortin-2 receptor provide a useful model system for understanding how ACTH emerged as the sole ligand for the melanocortin-2 receptor of bony vertebrates. This review will discuss how studies utilizing analogs of hACTH(1-24) have revealed two critical amino acid motifs in this ligand (HFRW and KKRRP) which are required for activation of the melanocortin-2 receptor. In addition, observations on the unique activation features of the melanocortin-2 receptor, as revealed from studies on Familial Glucocorticoid Deficiency, will be considered. Finally, the evolutionary implications of the relationship between MC2R and MRAP1 will be discussed.

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.
