The protein encoded by this gene contains two RING ring finger motifs. RING finger motifs are present in a variety of functionally distinct proteins and are known to be involved in protein-DNA or protein-protein interactions. This gene was found to be expressed during spermatogenesis, most likely in spermatocytes and/or in spermatids. Several alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jan 2011]
