      Background InformationThymocyte-expressed molecule involved in selection (Themis) is a highly conserved protein that has been shown to serve a key role in regulating T-cell development through TCR signaling, especially through the moderation of phosphorylation and calcium influx. It is also a critical component in the later stages of thymocyte development through the regulation of positive/negative T-cell selection, and is required for integration and maintenance of signals necessary to T-cell lineage commitment and maturation. Themis expression is observed in thymus, spleen, thymocytes between Pre-TCR and checkpoints positive in selectin, and at low levels in mature T-cells.

      Application NotesWestern Blot (Snap i.d.) Analysis: 2 µg/mL from a previous lot detected Themis in 10 µg of mouse thymocyte tissue lysate.

      Flow Cytometry Analysis: A previous lot was used by an independent laboratory in FC. (Vasily Rybakin, PhD., Gascoigne lab, Scripps Research Institute, La Jolla, CA

      Western Blot Analysis: A previous lot of this antibody was used to detect the presence and absence of Themis in Themis KO or WT thymocytes (Fu, G., et al. (2013) Nature. doi: 10.1038/nature12718)

      Immunopreciptiation Analysis: A previous lot of this antibody was used to immunoprecipitate Themis in WT thymocytes but not in Themis KO thymocytes (Fu, G., et al. (2013) Nature. doi: 10.1038/nature12718)

      UniProt SummaryFUNCTION: Plays a central role in late thymocyte development by controlling both positive and negative T-cell selection. Required to sustain and/or integrate signals required for proper lineage commitment and maturation of T-cells. Regulates T-cell development through T-cell antigen receptor (TCR) signaling and in particular through the regulation of calcium influx and phosphorylation of Erk.

      SUBUNIT STRUCTURE: Interacts with PLCG1, ITK and GRB2.

      SUBCELLULAR LOCATION: Cytoplasm. Nucleus

      TISSUE SPECIFICTY: Expressed in the thymus and to a lesser extent in the spleen but not detectable in nonlymphoid tissues. Highly expressed in thymocytes between the pre-T-cell antigen receptor (pre-TCR) and positive-selection checkpoints and expressed at low level in mature T-cells (at protein level).

      INDUCTION: Down-regulated by stimulation through the alpha-beta TCR.

      PTM: Phosphorylated on Tyr residues quickly after TCR stimulation.

      DISRUPTION: phenotype Mice are viable, are born at the expected mendelian frequency and present no gross abnormalities. They however display a blockade in late T-cell development with defects in thymocyte selection. The number of transitional CD4+CD8(int) thymocytes as well as CD4+ or CD8+ single-positive thymocytes is lower. Thymocytes show defective positive selection, resulting in fewer mature thymocytes. Negative selection is also impaired. A greater percentage of T-cells have CD4+CD25+Foxp3+ regulatory and CD62L(lo)CD44(hi) memory phenotypes compared to wild-type T-cells.

      SEQUENCE SIMILARITIES: Belongs to the themis family.
      Molecular Weight~72 kDa observed.
      UniProtKB/Swiss-Prot Q8BGW0 (THMS1_MOUSE) entry describes 5 isoforms produced by alternative splicing: Isoform 1 at 72.780 kDa, Isoform 2 at 69.544 kDa, Isoform 3 at 68.293 kDa, Isoform 4 at 59.082 kDa, and Isoform 5 at 30.040 kDa.
