背景信息

The PERK (Protein kinase R-like endoplasmic reticulum kinase) antibody is a crucial tool for studying the unfolded protein response (UPR) in eukaryotic cells. PERK, encoded by the *EIF2AK3* gene, is a transmembrane serine/threonine kinase located in the endoplasmic reticulum (ER). It acts as a sensor for ER stress, triggered by the accumulation of misfolded proteins. Upon activation, PERK dimerizes and autophosphorylates, initiating downstream signaling to restore proteostasis. This includes phosphorylating eukaryotic initiation factor 2α (eIF2α), which transiently attenuates global protein synthesis while selectively promoting translation of stress-responsive genes like *ATF4*. PERK also modulates oxidative stress and apoptosis pathways. Dysregulation of PERK signaling is linked to diseases such as neurodegenerative disorders, diabetes, and cancer. Antibodies targeting PERK (e.g., detecting total PERK or phosphorylated forms like p-PERK Thr980) are widely used in Western blotting, immunofluorescence, and immunohistochemistry to assess ER stress activation in research models. They help elucidate PERK’s role in cellular adaptation to stress, disease mechanisms, and therapeutic targeting. Validation of these antibodies is critical, as off-target effects can complicate interpretation. Commercial PERK antibodies are typically raised against specific epitopes in human or murine PERK, with cross-reactivity varying across species.
