CD43 (mouse) is a major leukocyte surface sialic acid protein that plays a critical regulatory role in T cell function.It positively affects the activation, proliferation, differentiation, trafficking and migration of T cells, particularly by enhancing migration to lymph nodes through ERM proteins.CD43 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived CD43 protein, expressed by HEK293 , with C-hFc labeled tag.

Mouse

The CD43 protein in mice emerges as the predominant cell surface sialoprotein of leukocytes, wielding a regulatory influence over various T-cell functions crucial to immune responses. CD43 positively regulates T-cell activation, proliferation, differentiation, trafficking, and migration, particularly enhancing T-cell trafficking to lymph nodes through its interaction with ERM proteins (EZR, RDX, and MSN). In addition to negatively regulating Th2 cell differentiation, CD43 steers T-cells towards a Th1 lineage commitment. It plays a pivotal role in inducing the expression of IFN-gamma during T-cell receptor (TCR) activation, affecting both CD4(+) and CD8(+) T-cells, and contributes to T-cell preparation for cytokine sensing and differentiation into effector cells by influencing the expression of cytokine receptors IFNGR and IL4R. Serving as a major E-selectin ligand, CD43 facilitates Th17 cell rolling on activated vasculature and subsequent recruitment during inflammation, mediating Th17 cell adhesion to E-selectin. Moreover, CD43 acts as a T-cell counter-receptor for SIGLEC1 and exhibits a protective role by shielding cells from apoptotic signals, thus promoting cell survival.
