The Building Blocks of HGH: Amino Acids

Proteins, including HGH, are complex molecules constructed from chains of amino acids. These amino acids act as the fundamental building blocks, and their specific order, or sequence, dictates the protein's three-dimensional structure and, consequently, its biological activity.

Key Structural Features and Variations

The human growth hormone molecule is not a simple linear chain; it folds into a complex three-dimensional structure. This folding is guided by the specific interactions between the individual amino acids. Research has identified conserved and unique amino acid residues within different domains of hGH that are critical for its interaction with the human growth hormone receptor. For instance, several clusters of amino acids, like those designated Gl, G2, G5, and G6, have been proposed to form the binding determinants of the hormone.

While the primary structure of hGH is largely consistent, there can be minor variations. For example, GH Human Recombinant produced in E.Coli typically results in a single, non-glycosylated polypeptide chain containing 191 amino acids. However, some sources indicate a Human Growth Hormone recombinant protein contains 192 amino acids, suggesting potential differences in production methods or isoforms.The protein encoded by this gene is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene itself, GH1; GH-N; GHB5; IGHD2; hGH-N; IGHD1A; IGHD1B, encodes for growth hormone, and variations within this gene can lead to different isoforms or predispositions to certain conditions like Idiopathic Short Stature (IGHD).

It's also important to note that the amino acid sequence can be influenced by translation and post-translational modifications. For instance, the 26 N-terminal amino acids often correspond to a signal peptide, which is essential for facilitating the hormone's secretion from the cell. Some research even points to the existence of less common splice sites, like an alternative 3' splice site for intervening sequence B, which could potentially alter the final protein product.作者：T Kobayashi·1991·被引用次数：22—Bullfrog GH was found to consist of190 amino acid residues.

Significance of the Amino Acid Sequence

The precise amino acid sequence of hGH is directly responsible for its diverse physiological functions. It stimulates the liver and other tissues to secrete insulin-like growth factor 1 (IGF-1), which mediates many of growth hormone's effects, including promoting bone and cartilage growth.An un-tagged recombinant protein corresponding to the aminoacids 27-217 of Human Growth Hormone.
