Detection of Human and Mouse ERK4 by Western Blot.
Western blot shows lysates of LNCaP human prostate cancer cell line, Raji human Burkitt's lymphoma cell line, and TS1 mouse helper T cell line. PVDF membrane was probed with 2 µg/mL of Rat Anti-Human/Mouse/Rat ERK4 Monoclonal Antibody (Catalog # MAB3914) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for ERK4 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.
ERK4 in Raji Human Cell Line.
ERK4 was detected in immersion fixed Raji human Burkitt's lymphoma cell line using Rat Anti-Human/Mouse/Rat ERK4 Monoclonal Antibody (Catalog # MAB3914) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Extracellular signal-regulated kinase 4 (ERK4) is a serine/threonine protein kinase also known as mitogen-activated protein kinase 4 (MAPK4), p63MAPK, and ERK3‑related kinase. ERK4 and the structurally similar ERK3 (MAPK6) lack the phosphoacceptor sequence T-X-Y present in other MAPKs. ERK4 complexes with ERK3 to activate MAPK-activated protein kinase 5 (MK5), also known as PRAK.
