Protein Target Info (Source: Uniprot.org)
|Protein Name||Antigen peptide transporter 2|
|Molecular Weight||75664 MW|
|Protein Function||Involved in the transport of antigens from the cytoplasm to the endoplasmic reticulum for association with MHC class I molecules. Also acts as a molecular scaffold for the final stage of MHC class I folding, namely the binding of peptide. Nascent MHC class I molecules associate with TAP via tapasin. Inhibited by the covalent attachment of herpes simplex virus ICP47 protein, which blocks the peptide-binding site of TAP. Inhibited by human cytomegalovirus US6 glycoprotein, which binds to the lumenal side of the TAP complex and inhibits peptide translocation by specifically blocking ATP-binding to TAP1 and prevents the conformational rearrangement of TAP induced by peptide binding. Inhibited by human adenovirus E3-19K glycoprotein, which binds the TAP complex and acts as a tapasin inhibitor, preventing MHC class I/TAP association.|
|Sequence Similarities||Belongs to the ABC transporter superfamily. ABCB family. MHC peptide exporter (TC 3.A.1.209) subfamily.|
|Subcellular Localization||Endoplasmic reticulum membrane; Multi-pass membrane protein. The transmembrane segments seem to form a pore in the membrane.|
|Alternative Names||Antigen peptide transporter 2;APT2;ATP-binding cassette sub-family B member 3;Peptide supply factor 2;Peptide transporter PSF2;PSF-2;Peptide transporter TAP2;Peptide transporter involved in antigen processing 2;Really interesting new gene 11 protein;TAP2;ABCB3, PSF2, RING11, Y1;|

Predicted bind size: 76KD
Observed bind size: 76KD
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
