Calcitonin and calcitonin receptors Mini - review
Calcitonin (CT) is a polypeptide hormone with 32 aminoacids syntetized primarily by the thyroid. Several evidences support the existence of nonthyroidal CT like peptide. The CT gene transcript also encodes a distinct peptide known as calcitonin gene related peptide (CGRP) which is a potent vasodilator and responsible for the stimulation of the glomerular filtration rate. In addition, a 37 amino...
متن کامل314 Electrophoretic Mobility and Agglutinability
I t has been recognized since 1954 (1) that the red cells of mice of some strains, notably A, can be specifically agglutinated more readily by anti-H-2 sera than those of others. This difference has been shown to apply to several 1t-2 antigens (2) and has been ascribed to a different cell concentration of antigenic determinants (3). Experience shows, however, that nonspecific agglutinability is...
متن کاملElectrophoretic Mobility Shift Assay (EMSA).
Transcriptional regulation of gene expression is controlled through the binding of sequence-specific DNA-binding proteins (transcription factors) to the regulatory regions of genes. The exact gene expression program of a cell is determined by the spectrum of transcription factors present with the nucleus of a cell. The presence of these factors is dependent upon the cell type being examined and...
متن کاملGlycosylation and Fc receptors.
Immunoglobulins and Fc receptors are critical glycoprotein components of the immune system. Fc receptors bind the Fc (effector) region of antibody molecules and communicate information within the innate and adaptive immune systems. Glycosylation of antibodies, particularly in the Fc region of IgG, has been extensively studied in health and disease. The N-glycans in the identical heavy chains ha...
متن کاملHuman placental calcitonin receptors.
Receptors for the hypocalcaemic hormone, calcitonin (CT), have been identified in a membrane fraction prepared from term human placentae. Binding of 125I-labelled salmon CT (125I-sCT) to the membranes was time- and temperature-dependent, saturable (Bmax. 58 +/- 11 fmol/mg of protein), of high affinity (Kd 80 +/- 21 pM) and poorly reversible. Species-specific CTs and CT analogues competed for 12...
