Function
Histone demethylase required for G2/M phase cell cycle progression (PubMed:20457893). Specifically demethylates dimethylated 'Lys-36' (H3K36me2) of histone H3, an epigenetic repressive mark, thereby acting as a transcription activator (PubMed:20457893). Regulates expression of CCNA1 (cyclin-A1), leading to regulate cancer cell proliferation (PubMed:20457893). In a complex with coregulator RCCD1, is also able to demethylate trimethylated 'Lys-36' (H3K36me3) of histone H3 (PubMed:24981860). Plays a role in transcriptional repression of satellite repeats, possibly by regulating H3K36 methylation levels in centromeric regions together with RCCD1 (PubMed:24981860). Possibly together with RCCD1, involved in proper mitotic spindle organization and chromosome segregation (PubMed:24981860). Plays a role in regulating alpha-tubulin acetylation and cytoskeletal microtubule stability (PubMed:28455245). Might function as a protein hydroxylase (PubMed:22851697, PubMed:24100311). Under stress conditions that cause a DNA damage response, acts as a histone protease by cleaving the N-terminal tail of histone H3 at the carboxyl side of monomethyl-lysine (Kme1) residues, preferably at monomethylated 'Lys-9' (H3K9me1) (PubMed:28982940). The histone variant H3F3A is the major target for cleavage (PubMed:28982940). UniProt

Subunit Structure
Can form homodimers (via JmjC domain) (PubMed:24100311, PubMed:28982940). Found in a complex with RCCD1 (PubMed:24981860). Interacts (via N-terminus) with RCCD1 (via N-terminus); this interaction stimulates H3K36me3 and H3K36me2 demethylation (PubMed:24981860, PubMed:28455245). Interacts (via JmjC domain) with HIST1H3A (PubMed:28982940). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
