MLKLAK Antibody (Center)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - MLKLAK Antibody (Center) AP8068c
    Western blot analysis of anti-MLKLAK-C284 Pab (Cat. #AP8068c) in HepG2 cell line lysate (35ug/lane). MLKLAK-C284(arrow) was detected using the purified Pab. This western blot detected isoform 2 of MLKLAK, the accession number for MLKLAK isoform 1 is Q9NYL2, NP_057737.
  • IHC-P - MLKLAK Antibody (Center) AP8068c
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by AEC 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 ZAK
Synonyms MLTK
Function Stress-activated component of a protein kinase signal transduction cascade. Regulates the JNK and p38 pathways. Pro- apoptotic. Role in regulation of S and G2 cell cycle checkpoint by direct phosphorylation of CHEK2. Isoform 1, but not isoform 2, causes cell shrinkage and disruption of actin stress fibers. Isoform 1 may have role in neoplastic cell transformation and cancer development. Isoform 1, but not isoform 2, phosphorylates histone H3 at 'Ser-28'.
Cellular Location Cytoplasm. Nucleus. Note=Translocates to the nucleus upon ultraviolet B irradiation
Tissue Location Ubiquitously expressed. Isoform 2 is the predominant form in all tissues examined, except for liver, in which isoform 1 is more highly expressed

MLKLAK is a member of the MAPKKK family of signal transduction molecules. It possesses an N-terminal kinase catalytic domain, followed by a leucine zipper motif and a sterile-alpha motif (SAM). This magnesium-binding protein forms homodimers and is located in the cytoplasm. The protein mediates gamma radiation signaling leading to cell cycle arrest and activity of this protein plays a role in cell cycle checkpoint regulation in cells. The protein also has pro-apoptotic activity.
