Disease relevance of SENP1

 

High impact information on SENP1

  • Both the NLS and the NES are located in the nonhomologous domains of SENP2 and are not conserved among other members of the SENP family [4].
  • Both reciprocal SENP1-MESDC2 (SEME) and MESDC2-SENP1 (MESE) fusion genes are transcribed in tumor-derived cells and their open reading frames encode aberrant proteins [5].
  • Using a PML desumoylation assay, we found that translocation-associated MESE proteins exhibit desumoylation capacities similar to those observed for WT SENP1 [5].
  • Thus, SENP1 could regulate AR-dependent transcription through desumoylation of HDAC1 [6].
  • The action of SENP1 on c-Jun transcription is independent of the sumoylation and phosphorylation status of c-Jun but is critically dependent on the desumoylation activity of SENP1 [7].
 

Chemical compound and disease context of SENP1

 

Biological context of SENP1

 

Anatomical context of SENP1

  • A COS cell expression system was used to demonstrate the activity of SENP1 in vivo [11].
  • In addition, sentrinized PML, a tumor suppressor protein that resides in the nucleus, was selectively affected by SENP1, whereas sentrinized RanGAP1, which is associated with the cytoplasmic fibrils of the nuclear pore complex, remained intact [11].
  • The tagged SUMO-1 was recruited into high molecular mass conjugates in the cell line, and expression of SENP1 promoted loss of these species, including the modified species of PML [12].
 

Associations of SENP1 with chemical compounds

 

Regulatory relationships of SENP1

  • Both ICP0 and SENP1 protease promoted the loss of SUMO-1 from the nucleus, observed both for the endogenous species and the cell line expressing the epitope-tagged SUMO-1 [12].
 

Other interactions of SENP1

  • HDAC1's repressive effect on AR-dependent transcription could be reversed by SENP1 and by deletion of its sumoylation sites [6].
  • Although SENP1 is rather similar in structure to the related protease SENP2, these proteases have different SUMO-processing activities [9].
  • SENP1 upregulation modulates the transcriptional activity of androgen receptors (ARs) and c-Jun, as well as cyclin D1 expression [2].
