Fork head protein homolog 2 - P41813 (FKH2_YEAST)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Transcription factor that regulates the expression of the CLB2 cluster of genes during the G2/M phase of the mitotic cell cycle (PubMed:10959837, PubMed:10894548, PubMed:10894549, PubMed:11562353, PubMed:12702877, PubMed:17283050, PubMed:24504085). The CLB2 cluster of genes includes mitotic regulators such as CLB1, CLB2, CDC5 and CDC20 as well as SWI5 and ACE2, transcription factors required for the subsequent temporal wave of cell cycle regulated gene expression in the M/G1 phase interval (PubMed:10959837, PubMed:10894548, PubMed:11562353). Involved in HMRa silencing (PubMed:10747051). FKH1 and FKH2 associate with the coding regions of active genes and influence, in opposing ways, transcriptional elongation and termination, and coordinate early transcription elongation and pre-mRNA processing (PubMed:12702877). Both FKH1 and FKH2 play a role as regulators of lifespan in collaboration with the anaphase-promoting complex (APC), likely through combined regulation of stress response, genomic stability, and cell cycle regulation (PubMed:22438832). FKH1 and FKH2 function also in controlling yeast cell morphology by preventing preudohyphal growth (PubMed:10747051, PubMed:10894548). Acts as a rate-limiting replication origin activator via its interactin with the origin recognition complex (ORC) (PubMed:22265405, PubMed:26728715). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
