Immunogène
Bacterially produced recombinant intracellular fragment of human SIT.
Signaling threshold regulating transmembrane adapt,SIT is a 21 kDa transmembrane adaptor protein expressed exclusively in lymphoid organs. It acts either as a positive or as a negative regulatory element in T cell activation and in T cell development. Binding to Grb2 plays a pivotal role in signal transduction. Hubener et al. (2001) determined that the SIT gene contains 5 exons and spans 1.8 kb of genomic DNA. The SIT promoter demonstrated strong transcriptional activity and potential binding sites for both ubiquitous and lymphoid-specific transcription factors.,SIT1
