SH2 domain-containing leukocyte protein of 76kD (SLP-76) is a hematopoietic adapter protein that is important in multiple biochemical signaling pathways and necessary for T cell development and activation 1). ZAP-70 phosphorylates SLP-76 and LAT as a result of TCR ligation. SLP-76 has amino-terminal tyrosine residues followed by a proline rich domain and a carboxy-terminal SH2 domain. Phosphorylation of Tyr113 and Tyr128 result in recruitment of the GEF Vav and the adapter protein Nck (2). TCR ligation also mediates an association between SLP-76 and Itk, which is accomplished in part via the proline rich domain of SLP-76 and the SH3 domain of ITK. Furthermore, the proline rich domain of SLP-76 binds to the SH3 domains of Grb2-like adapter Gads (3-4). In resting cells, SLP-76 is predominantly in the cytosol. Upon TCR ligation, SLP-76 translocates to the plasma membrane and promotes the assembly of a multi-protein signaling complex that includes Vav, Nck, Itk and PLCg1 (1). The expression of SLP-76 is tightly regulated: the protein is detected at very early stages of thymocyte development, increases as thymocyte maturation progresses, and is reduced as cells mature to CD4+ CD8+ double-positive thymocytes (5). Applications: Suitable for use in ELISA, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Immunohistochemistry (Paraffin): 1:100 Citrate/TBST Immunoprecipitation: 1:50 Optimal dilutions to be determined by the researcher.
