On the other hand ... The follicle-stimulating hormone receptor or FSH receptor (FSHR) is a transmembrane receptor that interacts with the follicle-stimulating hormone (FSH) ... The transmembrane domain contains two highly conserved cysteine residues that build disulfide bonds to stabilize the receptor structure. A highly … See more The follicle-stimulating hormone receptor or FSH receptor (FSHR) is a transmembrane receptor that interacts with the follicle-stimulating hormone (FSH) and represents a G protein-coupled receptor (GPCR). Its … See more The FSHR consists of 695 amino acids and has a molecular mass of about 76 kDa. Like other GPCRs, the FSH-receptor possesses seven membrane-spanning domains or See more In the ovary, the FSH receptor is necessary for follicular development and expressed on the granulosa cells. In the male, the … See more Some patients with ovarian hyperstimulation syndrome may have mutations in the gene for FSHR, making them more sensitive to gonadotropin stimulation. See more The gene for the FSHR is found on chromosome 2 p21 in humans. The gene sequence of the FSHR consists of about 2,080 nucleotides. See more Upon initial binding to the LRR region of FSHR, FSH reshapes its conformation to form a new pocket. FSHR then inserts its sulfotyrosine from … See more Upregulation Upregulation refers to the increase in the number of receptor sites on the membrane. Estrogen upregulates FSH receptor sites. In turn, FSH stimulates granulosa cells to produce estrogens. This synergistic activity … See more

WebDisulfide bonds are covalent interactions formed between the sulfur atoms of two cysteine residues. As structural bonds in proteins, disulfide bonds stabilize monomeric and multisubunit proteins [1] constituting the only natural covalent link between polypeptide strands. Furthermore, disulfide bonds are involved in enzyme catalysis [2], regulate … WebDisulfide bond plays a very much important role to form the secondary structure of protein. It is basically a covalent type bond. Disulfide bond is formed by the oxidation of sulfyhydryl or thiol group (S-H group), present only in Cysteine amino acid (non essential amino acid). It is also known as S-S bond . Disulfide bond is denoted by R-S-S-R1. hyperama shops
