Sumo1-ylation of human spermatozoa and its relationship with semen quality

6 Oct 2010

Abstract excerpt

Sumoylation is a post-translational modification involved in the regulation of several cell functions. Recent studies suggest its involvement in spermatogenesis, but occurrence and function of SUMO (small ubiquitin-like modifier) in mature spermatozoa remain unknown. We report the occurrence of several SUMO1-conjugated proteins, in a range of 20-85 kDa, in ejaculated spermatozoa. By cytofluorimetric analysis, we...
