Detection of TRIM in Human CD3+ T cells by Flow Cytometry. Human CD3+ T cells from peripheral blood mononuclear cells were stained with Goat Anti-Human TRIM Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4708, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.
Detection of Human TRIM by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells and Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human TRIM Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4708) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for TRIM at approximately 27 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Human TRIM (T cell receptor–interacting molecule) (also trat1; T cell receptor-associated transmembrane adaptor 1, and pp29/30) is a 27‑30 kDa, type III transmembrane protein, that is a member of the transmembrane adaptor protein (TRAP) family. It contains a short, 8 amino acid (aa) extracellular region, a 19 aa transmembrane region, and a 159 aa cytosolic tail. Its cytoplasmic tail contains several tyrosine motifs with the potential to bind to Src-homology 2 (SH2) domains of signaling proteins. TRIM is present in T cells and NK cells. Human TRIM shares 66% aa sequence identity with mouse TRIM.
