Data Example

Western Blot Detection of Human MAP4K5 by Western Blot. View Larger

Detection of Human MAP4K5 by Western Blot. Western blot shows lysates of 293T human embryonic kidney cell line, HT1080 human fibrosarcoma cell line, and Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human MAP4K5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8007) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for MAP4K5 at approximately 95 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MAP4K5

MAP4K5 (MAP Kinase Kinase Kinase Kinase 5; also known as KHS, MEKKK5, and GCKR) is a 94-96 kDa member of the STE (STErile 20 protein) subfamily, STE Ser/Thr protein kinase family, protein kinase superfamily of enzymes. It is ubiquitously expressed, and serves as an "intermediary" between GPCRs and cytosolic MAP kinases. It also interacts with Crk (CT10 Regulator of Kinase)-related adaptor molecules, facilitating the formation of signaling complexes around Tyr phosphorylated molecules. And finally, it represents an upstream component of a TNFR1 signaling pathway that requires activation of stress-activated protein kinases. Human MAP4K5 is 846 amino acids 9aa) in length. It contains a 258 aa kinase domain (aa 20-277) that is coupled to a 316 aa CNH (citron homology) domain (aa 506-826) which typically binds GTPases. There are two isoform variants. One shows a deletion of both Pro481 and Glu569, while another possesses a substitution of 16 aa for aa 569-846. Over aa 395-484, human MAP4K5 shares 83% aa sequence identity with mouse MAP4K5.
