  • Experimental Validation Results for CD4 Antibody (YA3557)
    Immunohistochemical analysis of paraffin-embedded mouse spleen tissue using CD4 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

    Immunocytochemistry analysis of HepG2 cells labeling CD4 with CD4 Antibody (YA3557) (HY-P83756) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with CD4 Antibody (YA3557) ((HY-P83756) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L（HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background

  • Function

    Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class II molecule:peptide complex. The antigens presented by class II peptides are derived from extracellular proteins while class I peptides are derived from cytosolic proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class II presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. LCK then initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of T-helper cells. In other cells such as macrophages or NK cells, plays a role in differentiation/activation, cytokine expression and cell migration in a TCR/LCK-independent pathway. Participates in the development of T-helper cells in the thymus and triggers the differentiation of monocytes into functional mature macrophages

  • Subcellular Localization

    Cell membrane; Single-pass type I membrane protein

  • Expression


    Tissue_specificity:Highly expressed in T-helper cells. The presence of CD4 is a hallmark of T-helper cells which are specialized in the activation and growth of cytotoxic T-cells, regulation of B cells, or activation of phagocytes. CD4 is also present in other immune cells such as macrophages, dendritic cells or NK cells
    Positive sample: Mouse spleen tissue lysate, Mouse thymus tissue lysates, mouse splenocytes, mouse spleen tissue, mouse thymus tissue.

  • Isoforms & Post-Translational Modification

    P06332 has 2 isomers: P06332-1: 51297 Da (predicted); P06332-2: 24473 Da (predicted).
    Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts;Phosphorylated by PKC; phosphorylation plays an important role for CD4 internalization

  • Subunit

    Forms disulfide-linked homodimers at the cell surface. Interacts with LCK. Interacts with PTK2/FAK1. Binds to P4HB/PDI. Interacts with IL16; this interaction induces a CD4-dependent signaling in lymphocytes. Interacts (via Ig-like V-type domain) with MHCII alpha chain (via alpha-2 domain) and beta chain (via beta-2 domain); this interaction increases the affinity of TCR for peptide-MHCII. CD4 oligomerization via Ig-like C2-type 2 and 3 domains appears to be required for stable binding to MHCII and adhesion between T cells and APCs
