Description

CD98, also known as 4F2, MDU1 and SLC3A2, is a single-pass type II transmembrane protein belonging to the SLC3A (solute carrier family 3A) transporter family. CD98 is expressed ubiquitously in all tissues with highest levels detected in kidney, placenta and testis and weakest level in thymus. As a common heavy chain, CD98 is required for the function of light chain amino-acid transporters (LAT) in sodium-independent transport of large neutral amino acids such as phenylalanine, tyrosine, leucine, arginine and tryptophan. The transporter exists as a disulfide-linked heterodimer of CD98 with one of several light chains (SLC7A5, SLC7A6, SLCA7A7, SLC7A8, SLC7A10 or SLCA7A11). CD98 plays an important role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine.  CD98 is also involved in the transport of L-DOPA across the blood-brain barrier, and thyroid hormones across the cell membrane in tissues such as placenta. CD98 is located selectively at cell-cell adhesion site.  CD98 constitutively and specifically associates with beta-1 integrins, including alpha-2/beta-1, alpha-3/beta-1, alpha-5/beta-1 and alpha-6/beta-1.  CD98 may help target LAT1 and LAT2 to the plasma membrane and regulate the transport activity.

Product Details

 

Gene Symbol: CD98; 4F2; SLC3A2; MDU1; 4F2HC; 4T2HC; NACAE; CD98HC

 

NCBI Gene ID: 6520

 

Uniprot Entry: P08195

 

Construct Details: Expressed as the combination of a heavy chain (HC) containing VH from anti-human CD98/LAT1 mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-CD98/LAT1 mAb and CL of human kappa light chain.  Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition.

 

Source: Mammalian cells stably expressing anti-CD98/LAT1 heavy chain and light chain (in human IgG1,k format) and growing in chemical-defined media with no animal components. 

 

M.W.: Calculated molecular mass (kDa): 147 (49 kDa for a single HC, 24.5 kDa for a single LC); Estimated by SDS-PAGE under non-reducing condition(kDa): 150

 

Purity: >95% judged by SDS-PAGE under reducing condition (see the gel image above, labeled as DTT "+")

 

Formulation: Supplied at 1.0 mg/ml in sterile PBS pH7.4 without any carrier protein or preservative (the concentration determined by UV absorption with an A280nm of 1.0 for 0.73 mg/ml of IgG and verified by SDS-PAGE and Coomassie blue staining)

 

Endotoxin Level: <0.1 EU per 1 μg of purified recombinant protein determined by the LAL method

 

Biological Activity: Binds CD98 protein (SKU#FCL0352) with high affinity (KD < 10 nM) in a function ELISA.  Recognizes cell surface CD98 and LAT1 complex by flow cytometry, IHC staining and fluorescent microscopy. Blocks CD98/LAT1-mediated amino acid transporter activity.
