Function

[SENP1_HUMAN] Protease that catalyzes two essential functions in the SUMO pathway: processing of full-length SUMO1, SUMO2 and SUMO3 to their mature forms and deconjugation of SUMO1, SUMO2 and SUMO3 from targeted proteins. Deconjugates SUMO1 from HIPK2. Deconjugates SUMO1 from HDAC1, which decreases its transcriptional repression activity.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Metal ions often stabilize intermolecular contacts between macromolecules, thereby promoting crystallization. When interpreting a medium-resolution electron-density map of the catalytic domain of human sentrin-specific protease 1 (SENP1), a strong feature indicative of an ordered divalent cation was noted. This was assigned as Co(2+), an essential component of the crystallization mixture. The ion displays tetrahedral coordination by Glu430 and His640 from one molecule and the corresponding residues from a symmetry-related molecule. Analysis of the data derived from a previous structure of SENP1 suggested that Co(2+) had been overlooked and re-refinement supported this conclusion. High-throughput automated re-refinement protocols also failed to mark the Co(2+) position, supporting the requirement for the incorporation of as much information as possible to enhance the value of such protocols.

The role of Co(2)+ in the crystallization of human SENP1 and comments on the limitations of automated refinement protocols.,Rimsa V, Eadsforth T, Hunter WN Acta Crystallogr Sect F Struct Biol Cryst Commun. 2011 Apr 1;67(Pt 4):442-5. Epub, 2011 Mar 24. PMID:21505236^[5]
