The Shc Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor Shc protein expression profile in cells. The kit can be used for measuring the relative amounts of Shc in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Shc.
Qualitative determination of Shc concentration is achieved by an indirect ELISA format. In essence, Shc is captured by Shc-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:
| 1. | A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values. |
| 2. | Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted. |

| UniProt Protein Function: | SHC1: an adaptor protein containing a SH2 domain and a PID domain within a PH domain-like fold. Couples activated growth factor receptors to signaling pathways. Participates in a signaling cascade initiated by activated KIT and KITLG/SCF. Six human isoforms are produced by alternative promoter usage and alternative splicing. Isoforms p66, p52 and p46 (P29353-1, -2, and -3), produced by alternative initiation, variously regulate growth factor signaling, oncogenesis, intracellular oxidant levels, and apoptosis. Isoforms p46 and p52, once phosphorylated, couple activated receptor tyrosine kinases to Ras via the recruitment of the GRB2/SOS complex, thus initiating the cytoplasmic proliferative Ras signaling cascade in various non-neuronal systems. Isoform p66 does not mediate Ras activation, but associates with mitochondria where it controls intracellular redox status, mitochondrial permeability, life span, and stress-induced apoptosis. p66 acts as a downstream target of the tumor suppressor p53 and is required for the ability of stress-activated p53 to induce elevation of intracellular oxidants, cytochrome c release and apoptosis. P66 deletion in mice decreases the incidence of aging-associated diseases, such as atherosclerosis, and significantly prolongs life span. Participates in signaling downstream of TIE2, the tyrosine kinase receptor for angiopoietin, and plays a role in the regulation of endothelial cell migration and sprouting angiogenesis. Interacts with tyrosine-phosphorylated CD3T, DDR2, LRP1, IRS4, SHP, FLT4, PDGFRB, TIE2, TrkA, -B and -C. Interacts with the NPXY motif of tyrosine-phosphorylated IGF1R and INSR in vitro via the PID domain. p66Shc is known to be activated by the mutant SOD1 associated with familial forms of amyotrophic lateral sclerosis (ALS), causing a decrease in the activity of Rac1 through a redox-sensitive regulation. In case of oxidative conditions, phosphorylation at S36 of isoform p66Shc, leads to mitochondrial accumulation p66 plays a role in mediating mitophagy and determining neuronal cell fate following acute oxygen glucose deprivation. Isoform p46 is localized to the mitochondria matrix. Targeting of isoform p46Shc to mitochondria is mediated by its first 32 amino acids, which behave as a bona fide mitochondrial targeting sequence. Isoform p52Shc and isoform p66Shc, that contain the same sequence but more internally located, display a different subcellular localization. |

| NCBI Summary: | This gene encodes three main isoforms that differ in activities and subcellular location. While all three are adapter proteins in signal transduction pathways, the longest (p66Shc) may be involved in regulating life span and the effects of reactive oxygen species. The other two isoforms, p52Shc and p46Shc, link activated receptor tyrosine kinases to the Ras pathway by recruitment of the GRB2/SOS complex. p66Shc is not involved in Ras activation. Unlike the other two isoforms, p46Shc is targeted to the mitochondrial matrix. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2011] |
