Germinal-center associated nuclear protein - O60318 (GANP_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores (PubMed:20005110, PubMed:20384790, PubMed:23591820, PubMed:22307388). Through the acetylation of histones, affects the assembly of nucleosomes at immunoglobulin variable region genes and promotes the recruitment and positioning of transcription complex to favor DNA cytosine deaminase AICDA/AID targeting, hence promoting somatic hypermutations (PubMed:23652018).

Subunit Structure
Isoform GANP: Component of the nuclear pore complex (NPC)-associated TREX-2 complex (transcription and export complex 2), composed of at least GANP, 2 copies of ENY2, PCID2, SEM1/DSS1, and either centrin CETN2 or centrin CETN3. The TREX-2 complex also associates with ALYREF/ALY (PubMed:23591820, PubMed:22307388). Interacts with RNA polymerase II subunit POLR2A and with the transcription elongation factor SUPT5H/SPT5 (PubMed:23652018, PubMed:22307388). Interacts (via FG-repeats) with NXF1; this interaction is not mediated by RNA (PubMed:20005110). Isoform GANP interacts with nuclear envelope proteins NUP62, NUP153 and RANBP2/NUP358; interaction with NUP153 is required for full localization at the nuclear pore complex (PubMed:20005110, PubMed:23652018). Interacts with several RNA helicases, including DHX9, DDX21, and DDX39A/DDX39, and with DNA topoisomerase TOP2A (PubMed:23652018). Directly interacts with AICDA/AID (PubMed:20507984). Interacts with the glucocorticoid receptor NR3C1 (PubMed:16914116). Isoform MCM3AP: Interacts with the glucocorticoid receptor NR3C1 (PubMed:16914116). Interacts with MCM3; this interaction leads to MCM3 acetylation (PubMed:9712829, PubMed:11258703, PubMed:12226073). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
