Description:
Comparison was made of the distribution of the insulin receptor sites on adipocyte and liver plasma membranes by using ferritin-insulin. Two-thirds of the occupied insulin receptors on adipocytes occurred in groups of two or more whereas up to two-thirds of the receptors on liver occurred as single receptors. Ferritin-insulin did not cause aggregation of the receptor sites in either tissue. The naturally occurring groups of receptors on adipocyte membranes may play a role in the greater sensitivity of adipocytes to insulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jarett, L -- Schweitzer, J B -- Smith, R M -- AM 20097/AM/NIADDK NIH HHS/ -- T32 AM 07296/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 5;210(4474):1127-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7003710" target="_blank"〉PubMed〈/a〉
