This gene transcribes naturally-occurring mRNAs that are read-through products of the neighboring jumonji domain containing 7 (JMJD7) and phospholipase A2, group IVB (PLA2G4B) genes. These read-through products contain in-frame segments from both genes but a function has yet to be determined for the predicted fusion proteins, which contain a partial JmjC domain and downstream C2 and phospholipase A2 domains. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Sep 2011].
