Scientific Data Images for Human MST1/STK4 Antibody

Detection of Human MST1/STK4 antibody by Western Blot.

Detection of Human MST1/STK4 by Western Blot.

Western blot shows lysates of human brain tissue, A172 human glioblastoma cell line, Jurkat human acute T cell leukemia cell line, and SH-SY5Y human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human MST1/STK4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4939) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for MST1/STK4 at approximately 55-60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
MST1/STK4 antibody in SH-SY5Y Human Cell Line by Immunocytochemistry (ICC).

MST1/STK4 in SH‑SY5Y Human Cell Line.

MST1/STK4 was detected in immersion fixed SH-SY5Y human neuroblastoma cell line using Goat Anti-Human MST1/STK4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4939) at 10 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.

Background: MST1/STK4

MST1 (mammalian sterile twenty-like 1; also Ser/Thr-protein kinase 4) is a 56 kDa class II GC (germinal center) kinase that contains an STE class catalytic domain. It is ubiquitously expressed, and found in both cytoplasm and nucleus. Human MST1 is 487 amino acids (aa) in length. It contains a Ser/Thr protein kinase domain (aa 30‑281), followed by two caspase cleavage sites (Asp326 and 349), two NLS motifs (aa 361‑370 and 441‑451) and a dimerization domain that spans the C‑terminal 57 amino acids. Upon dimerization, MST1 is activated via autophosphorylation at Thr183. Two MST1 variants exist; one shows a substitution of three Lys for the C‑terminal 85 aa, while a second shows a 27 aa substitution for the C‑terminal 55 amino acids. Over aa 285‑443, human MST1 shows 94% aa identity to mouse MST1.
