Introduction

The thyroid gland is an essential gland found in various vertebrates, and has thyroid follicles (comprised of thyroid epithelia cells), which are supplied by a dense network of blood capillaries. The thyroid tissue’s main function is the biosynthesis and secretion of the thyroid hormone, which is an essential biological molecule existing in either of two forms, T3 and T4. The activity of the thyroid gland is controlled through the neuroendocrine system, which involves the hypothalamus and the secretory actions of the pituitary gland. TSH plays a key role in stimulating the thyroxin-binding globulin (TGB) and the uptake of blood iodine ...

- Heterogeneous nuclear ribonucleoproteins is a protein that comprises of RNA binding proteins. It is a complex made up of RNA & proteins that is characterized by binding of premRNA. This occurs in the nucleus during the transcription and post transcriptional stages of preMRNA. The protein has different roles which include; prevent formation of secondary structures by preventing folding of pre-mRNA, inhibit the interaction with other proteins, usually has a link with the splicing apparatus and transportation of the mRNA away from the nucleus. This type of protein is a multidomain protein with multiple RNA binding proteins. RNA recognition Motif which is the commonest ...
