Scientific Data Images for Human LAT Antibody

Detection of Human LAT by Western Blot.

Western Blot shows lysates of HEL 92.1.7 human erythroleukemic cell line and Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 0.5 µg/ml of Mouse Anti-Human LAT Monoclonal Antibody (Catalog # MAB63341) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). Specific bands were detected for LAT at approximately 36, 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: LAT

LAT (Linker for activation of T cells; also pp36) is a 36-38 kDa type III (no signal sequence; extracellular N-terminus) transmembrane adaptor phosphoprotein. It is expressed on mast cells, NK cells, monocytes (but not macrophages), platelets and T cells. LAT is phosphorylated upon ligation of the TCR, GPVI, and Fc epsilon RI, and serves as an anchor for several SH2-domain containing signaling proteins, including PLCg1, SLP76 and Grb2. Human LAT is 262 amino acids (aa) in length. It contains a four aa extracellular segment with a 235 aa cytoplasmic domain (aa 28-262). Palmitoylation occurs on Cys26 and 29. There are 13 Ser/Thr phosphorylation sites plus five Tyr sites. Multiple potential splice variants are reported. There is an alternative start site 36 aa upstream of the standard site that may be accompanied by a deletion of aa 114-142. There is also a deletion of aa 88-97, and three substitutions: two aa for aa 215-262, 38 aa for aa 55-262, and 50 aa for aa 35-262. Over aa 30-113, human LAT shares 73% aa identity with mouse LAT.
