Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
Linker for activation of T cells (LAT) is a 36kD transmembrane adapter protein that is tyrosinephosphorylated following T-cell receptor (TCR) stimulation by ZAP-70 and Syk. Four distal tyrosine residues (Y132, Y171, Y191 and Y226 in human LAT) are crucial for its activity and subsequent signaling to downstream molecules. Tyrosine 191 has been shown to play a key role in T cell activation and to mediate Grb2 binding and Gads recruitment, thus mediating SLP-76 binding.
