Fsh alpha subunit
WebTarget Information. The four human glycoprotein hormones chorionic gonadotropin (CG), luteinizing hormone (LH), follicle stimulating hormone (FSH), and thyroid stimulating hormone (TSH) are dimers consisting of alpha and beta subunits that are associated noncovalently. The alpha subunits of these hormones are identical, however, their beta ... WebDetection of endocrine tumours secreting only the free α chains of the glycoprotein hormones (LH, FSH, hCG, TSH) are useful for TSHomas which may produce intact TSH and free alpha subunit. Interpretation: Some neuroendocrine and pituitary tumours secrete little or no intact hormone, but produce the common α subunit of glycoprotein hormones ...

WebThe effect of active immunization against inhibin on the response to superovulatory treatment by porcine FSH (pFSH) was investigated in cattle. Japanese black cows were sc injected with 1 mg of porcine inhibin alpha-subunit fragment (1-26) conjugated with rabbit serum albumin (inhibin-immunized group; n=14) or rabbit serum albumin alone ...
WebMembers of this family consist of an identical alpha subunit and a hormone-specific beta subunit. Alternative splicing results in two transcript variants encoding the same protein. FSH is secreted by gonadotropic cells in the pituitary gland and in conjunction with luteinizing hormone, induces egg and sperm production. WebCorifollitropin alpha. Corifollitropin α is a molecular hybrid obtained by the fusion of human Chorionic Gonadotropin β subunit carboxyl-terminal peptide with human FSH β chain ( Balen et al., 2004 ). The addition of carboxyl-terminal peptide, which has 4 connected oligosaccharidic chains, provides a slower absorption and a longer plasmatic ...
In humans, the gene for the alpha subunit is located at cytogenetic location 6q14.3. It is expressed in two cell types, most notably the basophils of the anterior pituitary. The gene for the FSH beta subunit is located on chromosome 11p13, and is expressed in gonadotropes of the pituitary cells, controlled by GnRH, inhibited by inhibin, and enhanced by activin.

WebThe approximately 20 kDa alpha subunit of human FSH shares 73% and 72% aa sequence identity with the mouse and rat orthologs, respectively. The approximately 21 kDa human FSH beta subunit shares 85% and 82% aa sequence identity with the mouse and rat orthologs, respectively. FSH is produced and secreted by the anterior pituitary gland.
