Detection of Human/Mouse ERK5/BMK1 by Western Blot. Western blot shows lysates of MDA‑MB‑468 human breast cancer cell line, Raji human Burkitt's lymphoma cell line, and Neuro‑2A mouse neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse ERK5/BMK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2848) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for ERK5/BMK1 at approximately 115 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
ERK5/BMK1 in HeLa Human Cell Line. ERK5/BMK1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Goat Anti-Human/Mouse ERK5/BMK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2848) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Extracellular signal-regulated kinase 5 (ERK5), also known as big mitogen-activated protein kinase 1 (BMK1) and MAPK7, is activated by a several mechanisms, including receptor tyrosine kinases, G protein-coupled receptors, and osmotic stress. Like ERK1 and ERK2, ERK5 contains the conserved Thr-Glu-Tyr activation motif in its activation loop. Unlike these ERKs, however, ERK5 contains a unique C-terminal domain that regulates its activation and nuclear translocation. ERK5’s upstream MAPK kinase has been identified as MEK5.
