Potassium voltage-gated channel subfamily H member 1 - Q60603 (KCNH1_MOUSE)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q60603: 3
 
Function
Pore-forming (alpha) subunit of a voltage-gated delayed rectifier potassium channel (PubMed:19671703, PubMed:23975098). Channel properties may be modulated by subunit assembly, but not by cyclic nucleotides (PubMed:19671703). Mediates IK(NI) current in myoblasts (By similarity). Involved in the regulation of cell proliferation and differentiation, as adipogenic and osteogenic differentiation in bone marrow-derived mesenchymal stem cells (MSCs). (data source: UniProt  )
Subunit structure
The potassium channel is probably composed of a homo- or heterotetrameric complex of pore-forming alpha subunits that can associate with modulating beta subunits. Heteromultimer with KCNH5/EAG2. Interacts with ALG10B (By similarity). Interacts with RABEP1 (PubMed:22841712). Interacts (via C-terminus) with CTTN. (data source: UniProt  )
Domain
The cyclic nucleotide-binding domain lacks residues that are essential for nucleotide-binding and cannot bind cyclic nucleotides (PubMed:19671703). Instead, residues from the C-terminal domain (the so-called intrinsic ligand) bind in the cavity that would be expected to bind cyclic nucleotides. Interaction with the C-terminal region hinders interaction with CALM and reduces the affinity for CALM. (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
