Data Examples
Detection of Human LTK by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human LTK Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4664) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for LTK at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Immunohistochemistry
LTK in Human Brain. LTK was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Sheep Anti-Human LTK Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4664) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hemotoxylin (blue). Specific staining was localized to neurons.

Background: LTK

LTK (Leukocyte tyrosine kinase; also protein tyrosine kinase 1) is a glycoprotein member of the tyrosine protein kinase family, insulin receptor subfamily of proteins. There are multiple isoforms that run between 50 and 100 kDa in SDS-Page. It is reportedly expressed in lymphocytes and cerebral cortex neurons, plus cardiomyocytes where it plays a role in cellular hypertrophy. Mature human LTK is an 848 amino acid (aa) type I transmembrane protein that is embedded in the ER. It contains a 408 aa extracellular domain (aa 17-424) plus a 415 aa cytoplasmic region (aa 450-864). The cytoplasmic region possesses multiple phosphotyrosines that interact with downstream signaling molecules. There is also a protein kinase domain between aa 510-786. LTK apparently undergoes dimer- and trimerization under certain circumstances. There are multiple splice variants for LTK. Two isoforms possess a common deletion of aa 274-334 that may be accompanied by a 27 aa substitution for aa 449-544. Another isoform shows an alternative start site at Met406 accompanied by a 17 aa substitution for Val449, while a fourth isoform contains a 51 aa substitution for aa 171-864. A final 50 kDa isoform shows a 28 aa substitution for aa 449-864. Over aa 17-424, human LTK shares 75% aa identity with mouse LTK.
