Designing a Western blot for SHC1? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.
Open the SHC1 Western Blot GuideFacts about SHC-transforming protein 1.
Isoform p46Shc and isoform p52Shc, once phosphorylated, couple activated receptor tyrosine kinases to Ras via the recruitment of the GRB2/SOS complex and are implicated in the cytoplasmic propagation of mitogenic signals. Isoform p46Shc and isoform p52Shc may thus function as initiators of the Ras signaling cascade in various non-neuronal systems.

Widely expressed. Expressed in neural stem cells but absent in mature neurons.
Cytoplasm.; [Isoform p46Shc]: Mitochondrion matrix. 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.; [Isoform p66Shc]: Mitochondrion. In case of oxidative conditions, phosphorylation at 'Ser-36' of isoform p66Shc, leads to mitochondrial accumulation.
