产品介绍 background:
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].

Function:
Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.

Subunit:
Associates with LCK. Binds to HIV-1 gp120 and to P4HB/PDI and upon HIV-1 binding to the cell membrane, is part of P4HB/PDI-CD4-CXCR4-gp120 complex. Interacts with HIV-1 Envelope polyprotein gp160 and protein Vpu. Interacts with Human Herpes virus 7 capsid proteins. Interacts with PTK2/FAK1; this interaction requires the presence of HIV-1 gp120.

Subcellular Location:
Cell membrane; Single-pass type I membrane protein. Note=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.

Post-translational modifications:
Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.

Similarity:
Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
Contains 1 Ig-like V-type (immunoglobulin-like) domain.

此抗体可识别55KDⅠ型单链穿膜糖蛋白。 CD4分子是存在于大多数辅助/诱导T细胞表面的59kDa的糖蛋白。正常淋巴组织中CD4的表达数量多于CD8，此抗体主要用于标记辅助/诱导T细胞，与CD8单抗联合使用对外周血淋巴细胞分型。 CD4抗原是HLA-II类分子和人类免疫缺陷病毒(HIV)-爱滋病的受体，在35-50%外周血淋巴细胞-辅助和诱导T细胞(Th/Ti)和70-80%人胸腺细胞上表达，在人的单核细胞表面也有低密度的表达。 CD4抗原有膜结合型和可溶性两种形式。Th/Ti可辅助Ig产生和T细胞毒T细胞的作用。
