Rabbit Anti-Human CD4 Monoclonal Antibody

• Cat.No.: CABTT-005RH

Specification

• Cat. No.: CABTT-005RH
• ProductOverview: Monoclonal Antibody toCD4; Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
• Antigen Description: This gene encodes a membrane glycoprotein of T lymphocytes that interacts with major histocompatibility complex class II antigenes and is also a receptor for the human immunodeficiency virus. This gene is expressed not only in T lymphocytes, but also in B cells, macrophages, and granulocytes. It is also expressed in specific regions of the brain. The protein functions to initiate or augment the early phase of T-cell activation, and may function as an important mediator of indirect neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcript variants encoding different isoforms have been identified in this gene.
• Clone: FQS7277
• Host animal: Rabbit
• CrossReactivity: Human
• Isotype: IgG1
• Immunogen: Recombinant fragment corresponding to the extracellular domain of Human CD4
• Positive control: Human fetal thymus and Human lymph node lysates, THP-1 cells
• Application: WB; ICC/IF; Flow Cyt
• Sequencesimilarities: Contains 3 Ig-like C2-type (immunoglobulin-like) domains. Contains 1 Ig-like V-type (immunoglobulin-like) domain.
• Post-translationalmodifications: Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
• Cellular localization: Cell membrane. Localizes to lipid rafts. Removed from plasma membrane by HIV-1 Nef protein that increases clathrin-dependent endocytosis of this antigen to target it to lysosomal degradation. Cell surface expression is also down-modulated by HIV-1 Envelope polyprotein gp160 that interacts with, and sequesters CD4 in the endoplasmic reticulum.
