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. [provided by RefSeq, Aug 2010]
CD4 involved in several pathways and played different roles in them. We selected most pathways CD4 participated on our site, such as Cell adhesion molecules (CAMs), Antigen processing and presentation, Hematopoietic cell lineage, which may be useful for your reference. Also, other proteins which involved in the same pathway with CD4 were listed below. Creative BioMart supplied nearly all the proteins listed, you can search them on our site.
CD4 has several biochemical functions, for example, MHC class II protein binding, coreceptor activity, enzyme binding. Some of the functions are cooperated with other proteins, some of the functions could acted by CD4 itself. We selected most functions CD4 had, and list some proteins which have the same functions with CD4. You can find most of the proteins on our site.
CD4 has direct interactions with proteins and molecules. Those interactions were detected by several methods such as yeast two hybrid, co-IP, pull-down and so on. We selected proteins and molecules interacted with CD4 here. Most of them are supplied by our site. Hope this information will be useful for your research of CD4.
