Immunofluorescence analysis of INSR [pY972] was done on 70% confluent log phase MCF7 cells with insulin treatment (100nM for 5 min). The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with INSR [pY972] Rabbit polyclonal Antibody (44800G) at 2µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing membrane localization. Panel e is untreated MCF7 cells. Panel f shows no primary antibody control. The images were captured at 20X magnification.

Biological actions of insulin and IGF-1 are mediated by their respective cell surface receptor tyrosine kinases that regulate multiple signaling pathways through activation of a series of phosphorylation cascades. The insulin receptor. Insulin/IGF-1 binding to the extracellular domain leads to autophosphorylation of downstream target proteins. These two receptors differ in sequence in regions that confer specificity for the designated ligand as well as in certain intracellular signaling domains, resulting in significant differences in the functional consequences of activation of each receptor. Defects in IR are the cause of various insulin resistance syndromes and IGF-1R defects may cause some forms of growth retardation. Both these signaling cascades are also important for the development of cancer.
