Fer was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human Fer Monoclonal Antibody (Catalog # MAB7229) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

FER [feline encephalitis virus (FES)-related kinase], also called Tyk3, is a widely expressed 822 amino acid (aa), 94 kDa intracellular non-receptor tyrosine kinase of the FES/FPS family. Human FER contains an FCH (microtubule/cytoskeleton interaction) domain (aa 1‑58), a coiled coil oligomerization region, an SH2 domain (aa 460‑550) and a kinase domain (aa 563‑816). FER is found both in the cytoplasm and the nucleus, and interacts with several transmembrane receptors, cytosolic proteins, and nuclear chromatin. Through its interactions and kinase activity, Tyk3/FER influences synapse formation, cytoskeletal rearrangement, cell survival and cell cycle progression. Within the region used as an immunogen, human Tyk3/FER shares 97% aa sequence identity with mouse Tyk3/FER. Potential human Tyk3/FER isoforms truncated at aa 308 and 478 have been described.
