| Description: | CD4 Protein, an integral membrane glycoprotein, plays a pivotal role in immune responses. In T-cells, it serves as a coreceptor for MHC class II molecules, interacting with the T-cell receptor and initiating intracellular signaling pathways. In macrophages and NK cells, CD4 contributes to differentiation, cytokine expression, and cell migration independently of TCR/LCK. Additionally, CD4 is crucial in T-helper cell development, monocyte differentiation, and acts as the primary receptor for HIV-1, down-regulated by HIV-1 Vpu, and Human Herpesvirus 7/HHV-7. CD4 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD4 protein, expressed by HEK293, with C-Avi, C-His labeled tag. The total length of CD4 Protein, Human (Biotinylated, HEK293, His-Avi) is 365 a.a., with molecular weight of 50-60 kDa. |
