Immunocytochemistry - Anti-IRS1 (phospho S636 + S639) antibody [25HCLC] (AB277770)

For immunofluorescence analysis, Insulin (200 ng/mL, 10 minutes) treated MCF-7 cells were fixed and permeabilized for detection of endogenous IRSpS636/639 using Anti-IRSpS636/639 Recombinant Rabbit Multiclonal Antibody (ab277770, 2 μ/mL) and labeled with Goat anti-Rabbit IgG (H+L) Secondary Antibody, Alexa Fluor^® 488 conjugate (1/2000). Panel a) shows representative cells that were stained for detection and localization of IRSpS636/639 protein (green), Panel b) is stained for nuclei (blue) with DAPI. Panel c) represents cytoskeletal F-actin staining using Alexa Fluor^® 555 Rhodamine Phalloidin (1/300). Panel d) is a composite image of Panels a, b and c clearly demonstrating cytoplasmic localization of IRSpS636/639. Panel e) shows untreated cells with no signal. Panel f) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Product details

What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:

- The sensitivity of polyclonal antibodies by recognising multiple epitopes
- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

The protein IRS1 also known as Insulin Receptor Substrate 1 is an important player in insulin signaling. It is a docking protein that plays a part in the signaling pathway of insulin and insulin-like growth factor (IGF) contributing to glucose homeostasis. The molecular weight of IRS1 is approximately 180 kDa. Expressed in various tissues including muscle liver and adipose tissue IRS1 facilitates the transmission of signals from activated cell surface receptors to intracellular pathways. Notable for its phosphorylation IRS1 undergoes change in state when interacting with receptor kinases impacting its role in cell signaling.

Biological function summary

IRS1 helps mediate the effects of insulin by acting as a downstream effector in the insulin signaling cascade. IRS1 functions in a complex manner binding with PI3K (phosphoinositide 3-kinase) after phosphorylation at specific tyrosine residues. This interaction is important for further signaling events leading to the regulation of glucose uptake lipid synthesis and gene expression. Besides its role in energy balance IRS1 plays a significant part in cell growth and differentiation driven by its ability to relay signals from the insulin and IGF receptors.

Pathways

IRS1 is heavily involved in the insulin signaling pathway and the PI3K-Akt pathway. Upon phosphorylation IRS1 binds to proteins such as the PI3K initiating a cascade that ultimately activates Akt resulting in anabolic processes within cells. The pathway is essential for regulating basic functions like metabolism growth and survival. IRS1's interaction with other related proteins like IR (insulin receptor) and IGFR (insulin-like growth factor receptor) highlights its integrative role in cellular processes related to energy and growth.

IRS1 is implicated in insulin resistance and type 2 diabetes. Changes in IRS1 phosphorylation patterns can disrupt normal insulin signaling leading to impaired glucose uptake and metabolic dysregulation. The protein's dysfunction is linked to obesity forming a connection through its interactions with other proteins like Akt and mTOR. Aberrant IRS1 activity may contribute to altered cell metabolism and growth promoting conditions like diabetes which highlights the importance of IRS1 in maintaining metabolic health.

Target data

Signaling adapter protein that participates in the signal transduction from two prominent receptor tyrosine kinases, insulin receptor/INSR and insulin-like growth factor I receptor/IGF1R (PubMed : 7541045, PubMed : 33991522, PubMed : 38625937). Plays therefore an important role in development, growth, glucose homeostasis as well as lipid metabolism (PubMed : 19639489). Upon phosphorylation by the insulin receptor, functions as a signaling scaffold that propagates insulin action through binding to SH2 domain-containing proteins including the p85 regulatory subunit of PI3K, NCK1, NCK2, GRB2 or SHP2 (PubMed : 11171109, PubMed : 8265614). Recruitment of GRB2 leads to the activation of the guanine nucleotide exchange factor SOS1 which in turn triggers the Ras/Raf/MEK/MAPK signaling cascade (By similarity). Activation of the PI3K/AKT pathway is responsible for most of insulin metabolic effects in the cell, and the Ras/Raf/MEK/MAPK is involved in the regulation of gene expression and in cooperation with the PI3K pathway regulates cell growth and differentiation. Acts a positive regulator of the Wnt/beta-catenin signaling pathway through suppression of DVL2 autophagy-mediated degradation leading to cell proliferation (PubMed : 24616100).
