Intracellular hyaluronan-binding protein 4 - Q5JVS0 (HABP4_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

RNA-binding protein that plays a role in the regulation of transcription, pre-mRNA splicing and mRNA translation (PubMed:14699138, PubMed:16455055, PubMed:19523114, PubMed:21771594). Negatively regulates DNA-binding activity of the transcription factor MEF2C in myocardial cells in response to mechanical stress (By similarity). Plays a role in pre-mRNA splicing regulation (PubMed:19523114). Binds (via C-terminus) to poly(U) RNA (PubMed:19523114). Involved in mRNA translation regulation, probably at the initiation step (PubMed:21771594). Seems to play a role in PML-nuclear bodies formation (PubMed:28695742). UniProt

Subunit Structure
Associates with polysomes (PubMed:21771594). Interacts with FMR1 (PubMed:21771594). Interacts with FXR1 and FXR2 (PubMed:21771594). Interacts with CHD3 (via C-terminus) (PubMed:12505151). Interacts (via C-terminus) with RACK1 (PubMed:14699138). Interacts with p53/TP53 (PubMed:16455055). Interacts (via N-terminus) with SRSF9; this interaction is direct (PubMed:19523114). Interacts with SYNCRIP; this interaction is direct (PubMed:19523114). Interacts with MEF2C (via N-terminus); this interaction decreases DNA-binding activity of MEF2C in myocardial cells in response to mechanical stress (PubMed:15862299). Interacts with PRMT1 (via N-terminus) (PubMed:16879614). Interacts with SPIN1 (By similarity). UniProt
The C-terminal region is necessary for nucleus and cytoplasmic localization (PubMed:19523114). The N-terminal region is necessary for nucleus and nuclear bodies localization (PubMed:19523114). Regions containing Arg-Gly-Gly repeats (RGG/RXR-box) may be preferentially methylated by PRMT1 (PubMed:16879614). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
