Alternative Name Syk
Background Syk is a member of the family of non-receptor type protein-tyrosine kinases and plays a crucial role in lymphocyte signaling and development. Syk is expressed in all haematopoietic cells and contributes to the signal transduction process by binding to a tyrosine-based activation motif (ITAM) of immune receptors, including Igalpha, TCRzeta, CD3epsilon, FcepsilonRIbeta, and FceRIgamma. Upon receptor activation, Syk binds to phosphorylated ITAMs via its two N-terminal SH2 domains thereby activating Syk and causing tyrosines in Syk to undergo auto-phosphorylation or phosphorylation. These phosphorylated sites can act as binding sites for other signaling molecules or help to regulate enzymatic activity. For example, in mast cells, Syk can activate downstream targets such as phospholipase Cgamma1 and VAV. Studies in Syk-/- mast cells identified defects in both the ERK-MAP and JNK-MAP kinase pathways. Syk migrates as 72 kDa in SDS/PAGE. (Predicted MW from SWISS-PROT is 72 kDa, Accession number P43405).
Research Area Immunology, Innate Immunity, Tyrosine Kinases, Signaling
Application Notes Western Blot: EB1 control lysate [50 µg (1 µg/ml)] is provided as a positive control (store lysate at -20°C).
Additional application: The FITC-conjugated format of clone 4D10 is useful in immunofluorescent staining and flow cytometric analysis.

anti-Spleen tyrosine Kinase (SYK) antibody Western blot analysis of Syk. Lysate from EB1 cells was probed with anti-Syk (clone 4D10) at concentrations of 0.125 (lane 1), 0.063 (lane 2), and 0.031 µg/ml (lane 3). Syk is identified as a band of ~72 kDa.
