Recombinant full-length human LYN B was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. LYN is a 56kDa tyrosine kinase that is similar to mouse T-lymphocyte-specific tyrosine kinase p56lck, v-yes, v-fgr and v-src and is expressed in a variety of tissues. LYN is expressed preferentially in B cells and can be coimmunoprecipitated with IgM, suggesting that LYN is physically associated with membrane-bound IgM and participates in antigen-mediated signal transduction. Crosslinking of membrane-bound IgM with antibody induces rapid increase in activities of LYN and LYN-associated phosphatidylinositol 3-kinase. Kinase Enzyme System contains: Kinase: LYN B, 10ug (Human, recombinant full-length). MW: ~85kDa. Substrate: SRC substrate (KVEKIGEGTYGVVYK-amide); derived from human p34cdc2 (amino acids 6-20). Other: Reaction Buffer, DTT, MnCl2. LYN B NCBI Database Entry: www.ncbi.nlm.nih.gov/gene/4067/.
