  • WB - SPAK Antibody (Center) AP7968c
    Western blot analysis of SPAK (arrow) using rabbit polyclonal SPAK Antibody (A363) (Cat. #AP7968c). 293T cell lysates either nontransfected (Lane 1) or transiently transfected (Lane 2) with the SPAK gene.
  • WB - SPAK Antibody (Center) AP7968c
    Western blot analysis of lysate from HepG2 cell line, using SPAK Antibody (A363)(Cat. #AP7968c). AP7968c was diluted at 1:1000. A goat anti-rabbit IgG H&L(HRP) at 1:10000 dilution was used as the secondary antibody. Lysate at 20ug.
  • WB - SPAK Antibody (Center) AP7968c
    Western blot analysis of lysate from 293 cell line, using SPAK Antibody (A363)(Cat. #AP7968c). AP7968c was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysate at 35ug.
  • WB - SPAK Antibody (Center) AP7968c
    Western blot analysis of anti-SPAK Pab (Cat. #AP7968c) in mouse liver tissue lysate. SPAK (arrow) was detected using purified Pab. Secondary HRP-anti-rabbit was used for signal visualization with chemiluminescence.
  • WB - SPAK Antibody (Center) AP7968c
    SPAK Antibody (A363) (Cat. #AP7968c) western blot analysis in U937 cell line lysates (35ug/lane).This demonstrates the SPAK antibody detected the SPAK protein (arrow).
  • WB - SPAK Antibody (Center) AP7968c
    Western blot analysis of SPAK (arrow) using rabbit polyclonal SPAK Antibody (A363) (Cat. #AP7968c). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected (Lane 2) with the SPAK gene.
  • IHC-P - SPAK Antibody (Center) AP7968c
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Protein Information
Name STK39
Synonyms SPAK
Function May act as a mediator of stress-activated signals. Mediates the inhibiton of SLC4A4, SLC26A6 as well as CFTR activities by the WNK scaffolds, probably through phosphorylation.
Cellular Location Cytoplasm. Nucleus. Note=Nucleus when caspase-cleaved.
Tissue Location Predominantly expressed in brain and pancreas followed by heart, lung, kidney, skeletal muscle, liver, placenta and testis

Background

SPAK is a serine/threonine kinase containing an N-terminal series of proline and alanine repeats (PAPA box), followed by a serine/threonine kinase catalytic domain, a nuclear localization signal, a consensus caspase cleavage recognition motif, and a C-terminal region. Northern blot analysis detects ubiquitous expression, most abundantly in brain and pancreas. SPAK can phosphorylate itself and an exogenous substrate in vitro. SPAK immunoprecipitates from transfected mammalian cells in a complex with another serine/threonine kinase that phosphorylates catalytically inactive SPAK. SPAK activates the p38 MAP kinase pathway in cotransfection assays. Full-length SPAK is expressed in the cytoplasm in transfected cells, while a mutant corresponding to caspase-cleaved STK39 localizes predominantly in the nucleus.
