CD4 (phospho Ser433) rabbit pAb

CD4 (phospho Ser433) rabbit pAb from ELK Biotechnology

SKU:
ABM109544
Product type
Primary Antibody
TargetCD4
ApplicationsIHC, IF, ELISA
Species / reactivityHuman, Mouse
Expression systemHighly 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.
PurityThe antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.

Product description

CD4 (phospho Ser433) rabbit pAb is a research-use antibody from ELK Biotechnology for studying CD4 in IHC, IF, ELISA workflows with listed reactivity for Human, Mouse. Specifications and supporting documents below should be reviewed when planning the experiment.

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],

Additional antibody information

Specificity Phospho-CD4 (S433) Polyclonal Antibody detects endogenous levels of CD4 protein only when phosphorylated at S433.

Immunogen
The antiserum was produced against synthesized peptide derived from human CD4 around the phosphorylation site of Ser433. AA range:401-450
Cellular localization
Cell membrane ; Single-pass type I membrane protein . Localizes to lipid rafts (PubMed:12517957, PubMed:9168119). 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.

Research target context

CD4CD4 molecule

View target guide

CD4 identifies CD4 molecule in Homo sapiens (Human). This target record connects NCBI Gene 920, UniProtKB P01730 and related ABMIUM catalogue products.

Biological function: CD4 is a cell-surface glycoprotein expressed on helper T cells and additional immune-cell subsets. It acts as a coreceptor for MHC class II during antigen recognition and supports T-cell receptor signalling.
