Harmonin - Q9Y6N9 (USH1C_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9Y6N9: 10
Anchoring/scaffolding protein that is a part of the functional network formed by USH1C, USH1G, CDH23 and MYO7A that mediates mechanotransduction in cochlear hair cells. Required for normal development and maintenance of cochlear hair cell bundles (By similarity). As part of the intermicrovillar adhesion complex/IMAC plays a role in brush border differentiation, controlling microvilli organization and length. Probably plays a central regulatory role in the assembly of the complex, recruiting CDHR2, CDHR5 and MYO7B to the microvilli tips (PubMed:24725409, PubMed:26812018). UniProt

Subunit Structure
Part of the IMAC/intermicrovillar adhesion complex/intermicrovillar tip-link complex composed of ANKS4B, MYO7B, USH1C, CDHR2 and CDHR5 (Probable). Part of a complex composed of USH1C, USH1G and MYO7A (PubMed:21709241). Interacts with F-actin (By similarity). Interacts with USH2A (PubMed:16301216). Interacts with SLC4A7 (PubMed:16301216). Interacts (via PDZ1 domain) with the C-terminus of USHBP1 (PubMed:11311560). Interacts (via N-terminus and PDZ 2 domain) with CDH23 (PubMed:19297620). Interacts with USH1G (PubMed:12588794, PubMed:20142502). Interacts with MYO7B (PubMed:24725409, PubMed:26812017). Interacts with CDHR2 and CDHR5; may mediate their interaction with MYO7B at the microvilli tip (PubMed:24725409, PubMed:26812017). Interacts (via PDZ 1 domain) with ANKS4B (PubMed:26812018, PubMed:26812017). UniProt
The N-terminal region constitutes an independently folded domain that has structural similarity with the CCM2 C-terminus, despite very low sequence similarity. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
