General Information

Product name Anti-CD4 Antibody
Short Description Rabbit polyclonal to CD4
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.

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.
Cellular Localization Cell membrane.
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.
