背景信息

The CD5 (Phospho-Tyr453) antibody is designed to detect the phosphorylated form of CD5 at tyrosine residue 453. a post-translational modification critical for its signaling function. CD5 is a transmembrane glycoprotein expressed on T cells and a subset of B cells (B-1a cells), where it modulates immune responses by regulating T-cell receptor (TCR) and B-cell receptor (BCR) signaling. Phosphorylation at Tyr453 occurs following antigen receptor engagement, mediated by kinases such as Lck or ZAP-70. and facilitates interactions with downstream signaling adaptors like GRB2. This phosphorylation event is associated with CD5's dual role in either dampening or fine-tuning immune activation, depending on cellular context.

Research using the CD5 (Phospho-Tyr453) antibody has elucidated CD5's involvement in autoimmune diseases, lymphoid malignancies (e.g., chronic lymphocytic leukemia), and T-cell-mediated tolerance. The antibody is widely employed in techniques like Western blotting, flow cytometry, and immunofluorescence to study CD5 activation dynamics. Its specificity is validated using phosphorylation-blocking peptides or CD5-deficient cell lines. Understanding CD5 phosphorylation provides insights into immune dysregulation and potential therapeutic strategies targeting its signaling pathways.
