Abstract excerpt
Several isoforms of growth hormone (GH) have been identified in humans. There are many reasons for this heterogeneity. At the genetic level, two genes encode GH: GH-N, expressed in the pituitary, and GH-V, expressed in the placenta. At the mRNA level, GH-N undergoes alternative splicing into 20K and 22K isoforms. Post-translationally, 22K GH undergoes modifications, such as acetylation at its amino terminus,...
