Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Mediates microtubule-dependent, anterograde transport connecting the Golgi network, endosomes, autophagosomes, lysosomes and plasma membrane, and participates in several cellular processes such as regulation of lysosomal pH, lysosome protein degradation, receptor-mediated endocytosis, autophagy, transport of proteins and lipids from the TGN, apoptosis and synaptic transmission (PubMed:10924275, PubMed:18817525, PubMed:18317235, PubMed:22261744, PubMed:15471887, PubMed:20850431). Facilitates the proteins transport from trans-Golgi network (TGN)-to other membrane compartments such as transport of microdomain-associated proteins to the plasma membrane, IGF2R transport to the lysosome where it regulates the CTSD release leading to regulation of CTSD maturation and thereby APP intracellular processing (PubMed:10924275, PubMed:18817525). Moreover regulates CTSD activity in response to osmotic stress (PubMed:23840424, PubMed:28390177). Also binds galactosylceramide and transports it from the trans Golgi to the rafts, which may have immediate and downstream effects on cell survival by modulating ceramide synthesis (PubMed:18317235). At the plasma memebrane, regulates actin-dependent events including filopodia formation, cell migration, and pinocytosis through ARF1-CDC42 pathway and also the cytoskeleton organization through interaction with MYH10 and fodrin leading to the regulation of the plasma membrane association of Na+, K+ ATPase complex (PubMed:20850431). Regulates synaptic transmission in the amygdala, hippocampus, and cerebellum through regulation of synaptic vesicles density and their proximity to active zones leading to modulation of short-term plasticity and age-dependent anxious behavior, learning and memory (By similarity). Regulates autophagic vacuoles (AVs) maturation by modulating the trafficking between endocytic and autophagolysosomal/lysosomal compartments, which involves vesicle fusion leading to regulation of degradation process (By similarity). Participates also in cellular homeostasis of compounds such as, water, ions, amino acids, proteins and lipids in several tissue namely in brain and kidney through regulation of their transport and synthesis (PubMed:17482562).

Subunit Structure
Homooligomer (By similarity). Interacts with DCTN1, KIF3A, RAB7A and RILP (PubMed:22261744). Interacts with CLN5 (PubMed:19941651, PubMed:14699076). May interact with HOOK1 (PubMed:15471887). Interacts with KCNIP3; this interaction is disrupted by intracellular increase of calcium level (PubMed:17189291). Interacts with TPP1, CLN6 AND CLN8 (PubMed:17237713). Interacts with MYH10; this interaction may play a role in regulation of cytoskeleton organization (PubMed:20850431). Interacts with SBDS (PubMed:20015955). Interacts with sodium/potassium-transporting ATPase complex (via ATP1A1) and fodrin heteromer (via SPTAN1); this interaction regulates their localization at the plasma membrane (Probable). Interacts with HSPA5 (Probable). Interacts (via dileucine motif) with AP3D1 and AP1G1; this interaction facilitates lysosomal targeting (PubMed:15598649). Interacts (via dileucine motif) with AP2A2 (PubMed:15598649). UniProt
Domain
The C-terminal (153-438) mediates KCNIP3 interaction and the cytoprotective activity (PubMed:17189291). the dileucine motif mediates AP1G1 and AP3D1 interaction (PubMed:15598649). 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.
