HCLS1-associated protein X-1 - O00165 (HAX1_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Recruits the Arp2/3 complex to the cell cortex and regulates reorganization of the cortical actin cytoskeleton via its interaction with KCNC3 and the Arp2/3 complex (PubMed:26997484). Slows down the rate of inactivation of KCNC3 channels (PubMed:26997484). Promotes GNA13-mediated cell migration. Involved in the clathrin-mediated endocytosis pathway. May be involved in internalization of ABC transporters such as ABCB11. May inhibit CASP9 and CASP3. Promotes cell survival. May regulate intracellular calcium pools. UniProt

Subunit Structure
Interacts with ABCB1, ABCB4 and ABCB11 (By similarity). Directly associates with HCLS1/HS1, through binding to its N-terminal region (PubMed:9058808). Interacts with CTTN (By similarity). Interacts with PKD2 (PubMed:10760273). Interacts with GNA13 (PubMed:15339924). Interacts with CASP9 (PubMed:16857965). Interacts with ITGB6 (PubMed:17545607). Interacts with PLN and ATP2A2; these interactions are inhibited by calcium (PubMed:17241641, PubMed:18971376). Interacts with GRB7 (PubMed:20665473). Interacts (via C-terminus) with XIAP/BIRC4 (via BIR 2 domain and BIR 3 domain) and this interaction blocks ubiquitination of XIAP/BIRC4 (PubMed:20171186). Interacts with TPC2 (PubMed:24188827). Interacts with KCNC3 (PubMed:26997484). Interacts with XPO1 (PubMed:23164465). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
