The melanocortin-2 receptor accessory protein (MRAP) is a type I integral membrane protein that is required for cell surface expression of the melanocortin 2 receptor (MC2R). Mutations in the N-terminal region of this protein are associated with familial glucocorticoid deficiency type II (OMIM#607398).Here we have investigated the expression and biochemical properties of MRAP using polyclonal antibodies to a conserved peptide sequence in the N-terminal r...

Objective: Variability in growth hormone (GH) responsiveness is evident in adult hypopituitary patients receiving recombinant GH (rhGH). Doses vary up to 4-fold for unexplained reasons. Deletion of exon 3 in the GH receptor (d3-GHR) has been linked to an increased response to GH treatment in children, although data are conflicting. We investigated the role of the d3-GHR polymorphism in determining GH responsiveness in adult GH deficient patients.Methods:...
