TCblR/CD320 Protein, Mouse (HEK293, Fc)

The TCblR/CD320 protein is a receptor for cobalamin-saturated transcobalamin (TCbl) that plays a key role in cobalamin uptake and is expressed on the plasma membrane, especially on follicular dendritic cells (FDCs). As a costimulator, TCblR promotes B cell responses, promoting differentiation and proliferation. TCblR/CD320 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived TCblR/CD320 protein, expressed by HEK293 , with C-hFc labeled tag.

TCblR/CD320 Protein, serving as the receptor for transcobalamin saturated with cobalamin (TCbl), assumes a pivotal role in cobalamin uptake. Positioned on the plasma membrane, it is notably expressed on follicular dendritic cells (FDC), facilitating interactions with germinal center B cells. Functioning as a costimulator, TCblR promotes B cell responses to antigenic stimuli, thereby fostering B cell differentiation and proliferation. Particularly influential in the differentiation of germinal center-B (GC-B) cells into memory B-cells and plasma cells (PC), TCblR engages in collaborative interactions with T-cells and follicular dendritic cells (FDC). Its involvement extends to augmenting the proliferation of PC precursors generated by IL-10. The interaction of CD320 with TCN2, mediated through its LDL-receptor class A domains, underscores its significance in cobalamin homeostasis and cellular processes.
