|Description||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).|
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

|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.|
