Activity summary

SHC also known as Src homology 2 domain-containing transforming protein or p52Shc is an adaptor protein involved in signal transduction pathways. It has a molecular mass of approximately 52 kDa. SHC contains an SH2 domain which facilitates its binding to tyrosine-phosphorylated activated receptors. This protein is ubiquitously expressed with notable levels in tissues like the brain heart and melanocytes. Its role as a signaling adaptor makes it an important component for cell communication and function.

Biological function summary

The SHC protein transmits signals from cell surface receptors to downstream effectors. It does so by linking activated receptors to the Ras-MAPK signaling cascade. SHC often part of larger protein complexes interacts with proteins such as Grb2 and SOS to relay signals necessary for cell growth and differentiation. This interaction leads to the activation of Ras and subsequent mitogen-activated protein kinase pathways influencing various cellular responses.

Pathways

SHC is a central component of the MAPK/ERK and PI3K/AKT pathways which are important for cell growth and survival. In these pathways SHC mediates signals from receptor tyrosine kinases like the epidermal growth factor receptor (EGFR). By interacting with EGFR and other receptors SHC helps propagate signals essential for cellular proliferation and survival. SHC associates with proteins like Grb2 and SOS linking RTKs to the Ras signaling cascade.

Associated diseases and disorders

SHC has been linked to cancer and cardiovascular diseases. In cancer abnormal SHC-mediated signaling can result from overexpression or mutation leading to unregulated cell proliferation. This abnormal activity often involves interactions with proteins like EGFR and Grb2 which drive oncogenic pathways. Regarding cardiovascular diseases changes in SHC expression or function can contribute to conditions like hypertrophy where SHC-associated pathways influence heart muscle growth and stress responses.
