The protein encoded by this gene contains a RING finger motif. The mouse counterpart of this protein has been shown to interact with Rela, the p65 subunit of NF-kappaB (NF-κB), and modulate NF-κB-mediated transcription activity. The mouse protein also binds ubiquitin-conjugating enzymes (E2s) and is a substrate for E2-dependent ubiquitination.[6]
