Biosynthesis of thyroid hormones

Thyroid hormones are iodinated tyrosine which is an amino acid.   Synthesis of thyroid hormones occurs in multiple steps 

 1. Synthesis of thyroglobulin: Thyroglobulin is synthesised by follicular epithelial cells just like any other protein synthesis by cells and is secreted into the colloid by exocytosis. So this protein is stored in the colloid. 

 2. Trapping and transport of iodide: Iodine is present in circulation as iodide ion. This iodide is taken up into the cytoplasm by NaI- symporter which is a secondary active transporter present on the basolateral membrane of thyrocytes. This Iodide then enters into the colloid via the apical membrane through the Cl-/I- exchanger which is also known as ‘pendrin’ 

 3. Organification: So now we got both iodide and thyroglobulin in the colloid. However, the iodide cannot react with tyrosine residues. For that it should be oxidised to iodine. So this process of oxidation of iodide to iodine and iodination of the tyrosine residues of the thyroglobulin is known as organification.  This occurs in presence of the enzyme thyroid peroxidase present on the apical membrane of thyrocytes.  Many tyrosine residues of thyroglobulin are iodinate either at single site forming monoiodotyrosines i.e MIT or two sites forming diiodotyrosines i.e DIT. 

 4. Coupling reaction: MIT and DIT are not thyroid hormones. It is the coupling or combination of these iodinated tyrosines which produces thyroid hormones. One MIT and one DIT couple to form triiodothyronine i.e. T3 and 2 DITS couple to form Tetraiodothyronine i.e T4 or thyroxine in presence of enzyme thyroid peroxidase. This is known as coupling reaction. 

So basically, thyroid hormones form within the thyroglobulin molecule.

When the gland is stimulated by Thyroid stimulating hormone, all these steps of synthesis of thyroid hormones i.e  synthesis of thyroglobulin, uptake of iodide, organification and coupling reaction are stimulated. 

Also, the follicular cells start taking up the stored iodinated thyroglobulin from the colloid by endocytosis. Intracellularly lysosomes fuse with the phagocytosed thyroglobulin and cleave T3 and T4 from thyroglobulin by proteases which are then released from the basolateral side and enter into the circulation. The separated amino acids are reused to produce thyroglobulin. The MIT and DIT which are not coupled are acted upon by the enzyme ‘deiodinase’ which as its name suggests detaches the iodine from the tyrosine both of which are recycled.

Membrane Transport⁣ ⁣ ⁣ Summary⁣ ⁣ ·         The plasma membrane protects the cell from the external environment as well as permitting the transport of specific substances in or out of the cell.⁣ ⁣ ·         Some substances(solutes) can move across a selectively permeable membrane. This means some substances are capable to pass through (e.g. oxygen, carbon dioxide, etc.)  whilst blocking others (e.g. ions)⁣ ⁣ ·         The plasma membrane has two processes to transport substances across:⁣ ⁣ o   Passive process⁣ ⁣ -          No energy is required (ATP)⁣ -          Simple and facilitated diffusion takes place⁣ ⁣ o    Active process⁣ ⁣ -          ATP is required (directly or indirectly)⁣ -          Primary, secondary or vesicular transport takes place⁣ ⁣ ⁣ Reference⁣ ⁣ ·         Marieb & Hoehn.

G-protein coupled receptors

G protein coupled receptors have an extracellular binding site to which the hormone binds and an intracellular cytoplasmic tail region to which G-proteins may bind.  

G proteins act as a switch and functionally couple the receptor to their target enzymes or ion channels. Switch means there is an inactive state when the hormone is not bound to the receptor and when the hormone binds, there is activation. G-proteins or heterotrimeric GTP binding proteins is a set of 3 proteins, G alpha, G beta and G- gamma which are present as an inactive complex bound to membrane just near the hormone receptor.   

The alpha subunit of G proteins is bound to GDP in inactive state. When the hormone binds to its receptor, receptor interacts with the G proteins and GDP bound to alpha subunit is replaced by GTP, which is now said to be in active state. This replacement of GDP with GTP causes alpha subunit to dissociate from beta and gamma subunits and move and associate with some other proteins causing  either opening/closing of ion channels or they affect the activity of enzymes like adenyl cyclase and phospholipase C. 

G proteins which stimulate adenyl cyclase activity are known as G stimulatory proteins i.e Galpha s. while that which inhibits their activity ate known as inhibitory G proteins i.e Galphai. The G proteins which affect the activity of phospholipase C are known as G q proteins. The effect of the hormone on the cell depends on the type of the receptor it binds for e.g. same hormone in one cell may have a receptor which is linked to stimulatory G proteins while in other cells it may have a receptor which is linked to inhibitory G proteins. By the change in the activity of these enzymes, second messenger systems or we can say signalling pathways are activated. 

 Adenylcyclase-cAMP pathway 

When adenyl cyclase enzyme is activated, it causes the conversion of ATP to cAMP. cAMP in turn cause the activation of cAMP dependent protein kinase A which causes phosphorylation of some proteins/enzymes in the cell. Now these proteins may be involved in biological reactions or these phosphorylated protein inturn activate or inhibit other proteins which are involved in cellular reactions. So ultimately this process affects the function of the cells. In addition, PKA can also increase/decrease the transcription of some genes. Close to these genes, is present a region known as cAMP-responsive element (CRE) region of DNA.  A subunit of PKA moves to the nucleus and phosphorylates another protein, the cAMP-responsive element binding protein (i,e CREB protein) which then binds to CRE and alters transcription of the genes where CRE is present. The set of proteins activated by cAMP varies in different cells. So adenyl cyclase activation  in different cells leads to different actions. However if same adenyl cyclase is activated by different ligands in the same cell, it leads to same actions. So in this pathway, cAMP acts as a second messenger.

Phospholipase C-IP3-DAG-Calmodulin pathway 

 When phospholipase C is activated by Gq proteins, it causes breakdown of the membrane phospholipid phosphatidylinositol 4,5 bi or di phosphate (PIP2) into IP3, i.e inositol triphosphate and Diacyl glycerol (DAG). Ip3 acts on IP3 receptor (IP3R) present on endoplasmic reticulum. This IP3R is itself a ligand gated calcium channel. When IP3 binds, it opens up causing release of calcium ions from ER into the cytososl. The calcium ions in turn bind with calmodulin causing activation/inhibition of calmodulin dependent protein kinases.  

DAG activates protein kinase C which then phosphorylates other proteins just as we saw for adenyl cyclase dependent kinases. So in this case IP3, DAG and calcium are second messengers.
