SNF1LK2 in Human Adipocytes. SNF1LK2 was detected in immersion fixed human adipocytes using 10 µg/mL Goat Anti-Human SNF1LK2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5737) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Detection of Human SNF1LK2 by Western Blot. Western blot shows lysates of human mesenchymal stem cells (MSC) grown in the absence (-) or presence (+) of StemXVivo™ Adipogenic Supplement (Catalog # CCM001). PVDF membrane was probed with 1 µg/mL of Goat Anti-Human SNF1LK2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5737), followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SNF1LK2 at approximately 125 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: SNF1LK2/SIK2

SNF1LK2 (Sucrose non-fermenting 1 like kinase 2) also known as SIK2 (Salt-inducible kinase 2) is a cytoplasmic 125 kDa member of the CAMK Ser/Thr protein kinase family, AMPK subfamily of enzymes. It is expressed in preadipocytes/adipocytes, with levels strongly induced during early differentiation. SNF1LK2 regulates the early phase of insulin signaling by phosphorylating IRS-1 on Ser794. Human SNF1LK2 is 926 amino acids (aa) in length and contains a protein kinase domain (aa 20‑271) with an ATP binding site (Lys49) and a catalytic loop (aa 140‑149), followed by a phosphorylation activation site at Thr175, a UBA (ubiquitin-associated) domain (aa 295‑335) and another PKA-dependent phosphorylation site at Ser587.
