Spermiogenesis represents the process through which haploid male germ cells differentiate from round spermatids into elongated spermatids and eventually the male gametes called spermatozoa. Haploid cell differentiation is unique to male germ cell development and many unique genes/proteins essential for this process have been discovered. SPEM1 is one of these spermiogenesis-essential proteins encoded by a testis-specific gene exclusively expressed in the developing spermatids. Inactivation of Spem1 in mice results in deformed spermatozoa characterized by "head-bent-back" abnormalities with 100% penetrance. Using yeast two-hybrid screening assays, we identified UBQLN1 as one of the SPEM1-interacting partners. UBQLN1 and SPEM1 were colocalized to the manchette of elongating spermatids. Since UBQLN1 functions through binding and directing poly-ubiquitinated proteins to the proteasome for degradation, interactions between UBQLN1 and SPEM1 suggest a role in the regulation of protein ubiquitination during spermiogenesis.
