Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q15036: 4
 
Function
Critical regulator of endosomal recycling of numerous surface proteins, including integrins, signaling receptor and channels (PubMed:15121882, PubMed:15769472). Binds to NPxY sequences in the cytoplasmic tails of target cargos (PubMed:21512128). Associates with retriever and CCC complexes to prevent lysosomal degradation and promote cell surface recycling of numerous cargos such as integrins ITGB1, ITGB5 and their associated alpha subunits (PubMed:28892079, PubMed:22492727). Also required for maintenance of normal cell surface levels of APP and LRP1 (PubMed:16712798, PubMed:19005208). Interacts with membranes containing phosphatidylinositol 3-phosphate (PtdIns(3P)) (PubMed:16712798). UniProt

Subunit Structure
Monomer (PubMed:21512128). Interacts with APP (via cytoplasmic YXNPXY motif) (By similarity). Interacts with KIF1B (By similarity). Interacts with the C-termini of P-selectin, PTC, LDLR, VLDLR, LRP1 and LRP8 (PubMed:11237770, PubMed:14739284, PubMed:15769472, PubMed:19005208). Interacts with KRIT1 (via N-terminus) (PubMed:16712798). Interacts with HRAS (PubMed:21512128). Interacts with ITGB1 and ITGB5 (via NPxY motif) (PubMed:22492727). Interacts with CCDC22, CCDC93, VPS26C and VPS35L; the interaction with VPS26C is direct and associates SNX17 with the retriever and CCC complexes (PubMed:28892079). UniProt
Domain
The PTB-like F3 module within the FERM-like domain mediates cargo recognition via their NPxY sequences, while the F1 module (Ras-associating) is responsible for interaction with membrane-bound HRAS. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
