The thyroid hormone receptor (TR) [1] is a type of nuclear receptor that is activated by binding thyroid hormone. [2] TRs act as transcription factors, ultimately affecting the regulation of gene transcription and translation. These receptors also have non-genomic effects that lead to second messenger activation, and corresponding cellular ...
Hemoglobin D has the basic structure and composition of normal adult hemoglobin. It is a globular protein containing prosthetic (non-protein) group called heme. There are four individual peptide chains, namely two α- and two β-subunits, each made of 141 and 146 amino acid residues, respectively.
The structure of Hb A consists of two α-globin chains bound to two β-globin chains to form a tetramer (a protein made up four protein chains). [3] When there is lower than normal production of α-globin , as in Hb H disease, the excess β-globin form β 4 -tetramers, termed Hemoglobin H.

Hemoglobin D was discovered in 1951 with one source stating it was the third variant discovered, [2] and another source claiming it was the fourth. [1] Later in 1962, it was found that five other regional variants of hemoglobin D all had the same chemical structure termed hemoglobin D-Punjab.
