Loading data... Dynamically generated for selected residues. Nodes can be dragged or clicked. Label: Selection: Name:

Once you see the structure neighbors, you can view the alignment in iCn3D by inputing a list of PDB chain IDs or AlphaFold UniProt IDs below. The PDB chain IDs are the same as the record names such as "1HHO_A". The UniProt ID is the text between "AF-" and "-F1". For example, the UniProt ID for the record name "AF-P69905-F1-model_v4" is "P69905". Chain ID List: BCIF/MMTF ID: PDB ID: Very high (pLDDT > 90) Confident (90 > pLDDT > 70) Low (70 > pLDDT > 50) Very low (pLDDT < 50) AlphaFold Uniprot ID: PAE Map: NCBI Protein Accession: PDB File: Multiple PDB Files: The custom JSON file on residue colors has the following format for proteins("ALA" and "ARG") and nucleotides("G" and "A"): {"ALA":"#C8C8C8", "ARG":"#145AFF", ..., "G":"#008000", "A":"#6080FF", ...} Residue Color File: The custom file for the structure has two columns separated by space or tab: residue number, and score in the range of 0-100. If you click "Apply Custom Color" button, the scores 0, 50 and 100 correspond to the three colors specified below. If you click "Apply Custom Tube", the selected residues will be displayed in a style similar to "B-factor Tube". Custom File: 1. Score to Color: 0: 50: 100: or 2. You can define your own reference numbers in a custom file using Excel, and then export it as a CSV file. An example file is shown below with cells separated by commas. refnum,11,12,,21,22,,10C,11C,20CThe first row defines the reference residue numbers, which could be any strings. The 1st cell could be anything. The rest cells are reference residue numbers (e.g., 11, 21, 10C, etc.) or empty cells. Each chain has a separate row. The first cell of the second row is the chain ID "1TUP_A". The rest cells are the corresponding real residue numbers for reference residue numbers in the first row. For example, the reference numbers for residues 100, 101, and 132 in the chain 1TUP_A are 11, 12, and 22, respectively. The fourth row shows another set of reference numners for the chain "1TUP_C". It could be a chain from a different structure. To select all residues corresponding to the reference numbers, you can simplay replace ":" with "%" in the Specification. For example, "%12" selects the residue 101 in 1TUP_A and the residue 111 in 1TUP_B. ".A%12" has the chain "A" filter and selects the residue 101 in 1TUP_A. Custom File: ID1: ID2: VAST+ based on VAST: VAST+ based on TM-align: All chains will be aligned to the first chain in the comma-separated chain IDs. Each chain ID has the form of PDBID_chain (e.g., 1HHO_A, case sensitive) or UniprotID (e.g., P69905 for AlphaFold structures). Chain IDs: (Note: To align chains in custom PDB files, you could load them in "File > Open File > PDB Files (appendable)" and click "Analysis > Defined Sets". Finally select multiple chains in Defined Sets and click "File > Realign Selection".) All chains will be aligned to the first chain in the comma-separated chain IDs. Each chain ID has the form of PDBID_chain (e.g., 1HHO_A, case sensitive) or UniprotID (e.g., P69905 for AlphaFold structures). Chain IDs: The sequence alignment (followed by structure alignment) is based on residue numbers in the First/Master chain: (Note: To align chains in custom PDB files, you could load them in "File > Open File > PDB Files (appendable)" and click "Analysis > Defined Sets". Finally select multiple chains in Defined Sets and click "File > Realign Selection".) All chains will be aligned to the first chain in the comma-separated chain IDs. Each chain ID has the form of PDBID_chain (e.g., 1HHO_A, case sensitive) or UniprotID (e.g., P69905 for AlphaFold structures). Chain IDs: Each alignment is defined as " | "-separated residue lists in one line. "10-50" means a range of residues from 10 to 50. Option 1: Option 2: All chains will be aligned to the first chain in the comma-separated chain IDs. Each chain ID has the form of PDBID_chain (e.g., 1HHO_A, case sensitive) or UniprotID (e.g., P69905 for AlphaFold structures). Chain IDs: Each alignment is defined as " | "-separated residue lists in one line. "10-50" means a range of residues from 10 to 50. Please specify the mutations with a comma separated mutation list. Each mutation can be specified as "[uppercase PDB ID or AlphaFold UniProt ID]_[Chain Name]_[Residue Number]_[One Letter Mutant Residue]". E.g., the mutation of N501Y in the E chain of PDB 6M0J can be specified as "6M0J_E_501_Y". For AlphaFold structures, the "Chain ID" is "A". If you load a custom structure without PDB or UniProt ID, you can open "Seq. & Annotations" window and find the chain ID such as "stru_A". The part before the underscore is the structure ID, which can be used to specify the mutation such as "stru_A_...". Remember to choose "Show Mutation in: Current Page".

Function | This transporter is involved in sodium-independent, high-affinity transport of large neutral amino acids such as phenylalanine, tyrosine, leucine, arginine and tryptophan and involved in guiding and targeting of LAT1 and LAT2 to the plasma membrane. When associated with SLC7A6 or SLC7A7,it acts as an arginine/glutamine exchanger, following an antiport mechanism for amino acid transport, influencing arginine release in exchange for extracellular amino acids. It plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine. It is required for normal and neoplastic cell growth. When associated with SLC7A5/LAT1, it is also involved in the transport of L-DOPA across the blood-brain barrier, and that of thyroid hormones triiodothyronine (T3) and thyroxine (T4) across the cell membrane in tissues such as placenta. Involved in the uptake of methylmercury (MeHg) when administered as the L-cysteine or D,L-homocysteine complexes, and hence plays a role in metal ion homeostasis and toxicity. When associated with SLC7A5 or SLC7A8,it get involved in the cellular activity of small molecular weight nitrosothiols, via the stereoselective transport of L-nitrosocysteine (L-CNSO) across the transmembrane. Together with ICAM1, it regulates the transport activity LAT2 in polarized intestinal cells, by generating and delivering intracellular signals. When associated with SLC7A5, it plays an important role in transporting L-leucine from the circulating blood to the retina across the inner blood-retinal barrier. When associated with LAPTM4B, it recruits SLC3A2 and SLC7A5 to lysosomes to promote leucine uptake into these organelles and is required for mTORC1 activation. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
