[5][6] The protein encoded by this gene contains a RING zinc finger, a motif known to be involved in protein-protein interactions.

This protein associates transiently with microtubules, myosin, and titin during muscle sarcomere assembly.

It may act as a transient adaptor and plays a regulatory role in the assembly of sarcomeres.

Four alternatively spliced transcript variants encoding distinct isoforms have been described.
