NCBI Protein Information
IBR domain-containing protein
NCBI Summary
Encodes ARIADNE14 (ARI14), a putative ubiquitin E3 ligase. ARI14 and an inversely transcribed gene KPL generate a sperm-specific natural cis-antisense siRNA pair. In the absence of KPL, ARI14 RNA levels in sperm are increased and fertilization is impaired.

UniProt Comments
Might act as an E3 ubiquitin-protein ligase, or as part of E3 complex, which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes and then transfers it to substrates (PubMed:12446796). Regulates negatively male gametophyte formation and double fertilization (PubMed:20478994).
