The following points highlight the two categories of non-peptide hormones produced by posterior pituitary. The categories are: 1. Functions of Vasopressin 2. Functions of Oxytocin. Category # 1. Functions of Vasopressin: (1) Antidiuretic effect: In mammals, following a rise in plasma osmolarity, vasopressin or antidiuretic hormone (ADH) binds to V2 receptors on the basolateral plasma membrane of the distal tubules [...]
Membrane Receptor # 1. Receptor Kinase: These membrane receptors contain the effector activity, such as tyrosine or serine kinase activity as an intrinsic part of the structure. The best characterised of these receptors are the protein kinase, as typified by the receptors for insulin, IGF-1, epidermal growth factor (EGF), and platelet- derived growth factor (PDGF) receptors. Each of these [...]
