EH domain-containing protein 1 - Q9H4M9 (EHD1_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
ATP- and membrane-binding protein that controls membrane reorganization/tubulation upon ATP hydrolysis. In vitro causes vesiculation of endocytic membranes (PubMed:24019528). Acts in early endocytic membrane fusion and membrane trafficking of recycling endosomes (PubMed:15020713, PubMed:17233914, PubMed:20801876). Recruited to endosomal membranes upon nerve growth factor stimulation, indirectly regulates neurite outgrowth (By similarity). Plays a role in myoblast fusion (By similarity). Involved in the unidirectional retrograde dendritic transport of endocytosed BACE1 and in efficient sorting of BACE1 to axons implicating a function in neuronal APP processing (By similarity). Plays a role in the formation of the ciliary vesicle (CV), an early step in cilium biogenesis. Proposed to be required for the fusion of distal appendage vesicles (DAVs) to form the CV by recruiting SNARE complex component SNAP29. Is required for recruitment of transition zone proteins CEP290, RPGRIP1L, TMEM67 and B9D2, and of IFT20 following DAV reorganization before Rab8-dependent ciliary membrane extension. Required for the loss of CCP110 form the mother centriole essential for the maturation of the basal body during ciliogenesis (PubMed:25686250). UniProt

Subunit Structure
Homooligomer, and heterooligomer with EHD2, EHD3 and EHD4, ATP-binding is required for heterooligomerization (PubMed:16251358, PubMed:17233914, PubMed:18331452). Interacts (via EH domain) with MICALL1 (via NPF1 motif); the interaction is direct and recruits EHD1 to membranes (PubMed:19864458, PubMed:20106972). Interacts with RAB35; the interaction is indirect through MICALL1 and recruits EHD1 to membranes (By similarity). Interacts (via EH domain) with PACSIN2 (via NPF motifs); regulates localization to tubular recycling endosome membranes (PubMed:23596323). Interacts with PACSIN1 (By similarity). Interacts with RAB8A (PubMed:19864458). Interacts with FER1L5 (via second C2 domain) (By similarity). Interacts with MYOF (By similarity). Interacts with ZFYVE20 (PubMed:15020713). Interacts (via EH domain) with RAB11FIP2 (PubMed:16251358). 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.
